Assignment 12

From a news article or internet information, find an example of an organization that is installing an ERP package. If possible get a copy of the over-all project plans and analyze the various activities and compare them with a standard SDLC

Enterprise Resource Planning (ERP) is an integrated business planning which also handles long range development plan. Nowadays, ERP is being use as a business strategy to manage the business and to have an effective plan. The typical flow of ERP is first you have the input then it will be in the work flow which handles money, people, facilities and materials. After this process, it will result to be your goal. The hierarchy of the ERP is business strategy, business model, business process, organization, MIS, and database.

Ideal ERP System

Manufacturing

            This handles manufacturing process and resources work flow and others. It organizes the main flow of the system.

Financials

            This is for the management of payments and other transaction that involve with the cash.

Human Resource

            Human resource will manage the benefits of the employee and employers. This will also handles the primary function of the entire employee like attendance, labor and rules.

Supply chain management

            This will be in charge with the inventory management and other material and product needed. It will also handle transportation and distribution together with the procurement planning.

Customer Relationship Management

             The main function of this is for the marketing strategy of the system. This will manage the service towards the customer.

           

Example of enterprise that implement ERP

Cargill

                “The team and the system has earned the respect and confidence of the users. The Lynx system is providing capabilities to the business beyond what one thought was possible.”

            Cargill provide a centralize ERP application that specifies for the Agricultural business and they improve the functionality and efficiency of the system at the same time, they maintain the cost. Base on the their source, the key benefits can  reduce the annual IT operating cost of 13 to 42 dollars and you will have a centralize project. You will also benefit about the solid and scalable platform for the additional function that you want. The system will also handles risk management and this company is one of the top international food provider which only prove that the system is working and useful.

Barnes and nobles    

Barnes and Nobles is a book store that made it to the top with the use of ERP. One of their strategies is to give 40 percent discount to the specific book to acquire customers. They also use the television to indorse their product which is a big success because until now, people in America still remember the advertisement if they saw it during that time. They also offer CD’s and DVD’s which helps to their popularity and they also make partner with different corporation. They also buy companies to expand their network like sparknote.com which is a leading web aid Webster.

Mercedes Benz

            Mercedes Benz is a well know industry in the whole world because of its product. One key reason for the success of the Mercedes Benz is using Baan’s enterprise resource planning software. It’s an automated data collection and because of the Baan’s ERP, it enables the system to have just-in-time and just-in-sequence parts delivery.

Sun Microsystem

            Sun microsystem is a corporation that sells computer and computer parts. They also sell hardware and software component. This is the first unix work station and they also develop platform like java platform, MySQL and NFS. One of their strategy is to make an open source software and they will use it to indorse their product. By implementing the ERP, they minimize the cost in their facility, improve the accessibility, achieve flexibility like changing its component from present to future which means that its capabilities involves the future specification.

SDLC vs planning with ERD

            Base on what I have learned in the previous assignment about System Development Life Cycle (SDLC), it is only effective for the simple operation and it is not effective if you will use this method for the complex and wide structures.  As what I have observed about the ERD planning strategy of the company listed above, ERD help it by preparing the system to the future. It is flexible enough to adopt specific changes in the system. It is more strategically base planning for the long range planning and it is very effective compare to SDLC. In my opinion, SDLC is for rapid and short range development only and for that, it is not applicable and adoptable for changes in the near future. The structure of SDLC is constant compare to ERD.  In managing the system, ERD help a lot because it is adoptable for the need of the user.

Conclusion

            Not all company will success by the help of ERD but it will make a big difference. Not all the time ERD is applicable and it also has its own advantage and disadvantage like in a practical manner when using ERD which the system involves is temporary or not a candidate for the long range development. Sometimes, SDLC will do the work and vice versa.

SAD assessment 11

Assignment 11

You were tasked by the IC-dean to evaluate the enrollment system of the university, list and briefly describe the characteristics that an analyst (you) examines when choosing or defining deployment environment.

In the University of Southeastern Philippines, one crucial part of the system is the enrollment system. It involves the participation of staff and all the students who want to study in the said university.  The said system is very important especially for the student and I must say that it is the busiest system in enrollment time.

If I a am going to evaluate the enrollment system, my personal knowledge about the system and my observation will not be enough for evaluation and must seek help for friends and people who can contribute idea and observation about the system.

Correctness

            Correctness is very important in the system and the exchange of information’s running in the system must be accurate. Correctness is one characteristic that needs to be visible in the system like the enrollment system. A slight correction in the details input and output may ruin the system. The level of correctness in the enrollment system must be in the prioritized list because the system is build primarily for the student.

            The enrollment system of the university is being built to cater the need of the student. Slight observation about the output of the enrollment system which is in the COR is not that perfect. Sometimes details in the COR is not one hundred percent accurate. The common error is the room and subject time details which is very important to the student of the university. As I observe, the error occur during the encoding and assigning of the room.

Flexibility

            The enrollment must cater the needs of the student in a flexible manner. That means the system will make the students effort to be less difficult. The system must shoulder the needs of the student as much as possible.

           

            In the system, I must say that it is not flexible enough because in the enrollment process, student is always having trouble in the enrollment time. The time which the student is mostly exhausted besides class hour and passing of requirements. The student is sometimes blame because of they are too slow in processing the requirements for the enrollment and I must disagree with this. Even those fast people who can provide the requirement on time is not happy in the system flexibility to ward the student. The system is running slow because of the number of students and the system must be re build in order to solve those delays in the transaction of the system.

Another problem is the adding dropping system which is part of the enrollment system. In my perspective, some subject can be added and process during the enrollment day especially those delay subject. The case is that sometimes, the students are not allow to do that because they need to wait until the adding and dropping schedule will be open. In that case, students are obliged to pay for the adding and dropping for every subject that needs to be added and drop. It is impractical and it didn’t cater the need of the student especially in the case of money which is one of the major problems in this university.

Time

The time is an important factor during the enrollment. Time will determine every process on how fast or slow the system is. In the university, the enrollment system eat allot of time of student especially the freshmen. Their number can be catered by the system and for me, the time to take the transaction to be finish is slow. The slow process of the system is a result of some factor which is the number of enrollee, employee, and facility provided. In the facility area, I can say that it is enough to cater our needs but in the number of employee with respect to the number of the student then it is inappropriate especially in the cashier and registrar. Another thing that I observe during the registrar is the cutting of lines which is I admit that I’m one of those who cut lines during the enrollment. Simple reason is the slow process of the system and the student demands peed.

Facilities

            The facility is another factor that contributes time and performance in the system. The higher the quality of the facility does, the faster the performance will become. In the enrollment system, facility is not that important although it is required because facility accompany the system to work properly. Without facility, the enrollment system will stop running. In this university, maybe additional facility is needed because the population of the school is increasing rapidly.

Structure

            Structure is the architecture of the system and it includes the flow of the system. Structure is also important in evaluating the system because in the structure, you can visualize the function of the system which is necessary when you evaluate.

            The structure of the enrollment system is good except for the registrar section because I think that section have more space for improvement.

Assignment 10

With reference to assignments 8 and 9, what characteristics does an analyst (you) examine when evaluating DFD quality?

            Data flow diagram is a graphical way of representing a data flow in a system. It is an effective way of overviewing a system in a very clear manner. In planning a system, DFD must be presented because by viewing the diagram, you can determine what is missing and what is to be removed in the system flow. In making a DFD, we make sure that the details are correct and every process has been evaluated to insure the quality and integrity of the DFD. In making DFD, we must also follow some guideline to follow and some characteristic that needs to be developed.

            When I evaluate the data flow diagram quality, I evaluated first if the structure is match to the real system. When evaluating the DFD, by just viewing it as a general structure, you can see what it means because DFD is a diagram that explains the context of the system in a simple manner. I can say that it is very understandable when we look at it because DFD especially those context diagrams which is a part one of the DFD is being created for those people who are not so technical in nature. You need be analyzer and a good cretic so that you will know if the DFD is being built for a specific system and not for the foreign structures. In criticizing a DFD, we must be reminded that we need to see the actual structure before criticizing the DFD structure. That must be in the first of your list in evaluating and criticizing DFD.

            In the DFD part, when examining it, you must first know the structure and every details of the diagram. You need to know first the function and limitation of the structure inside the diagram. To know the diagram first is the first step in examining the diagram. The structure is a very important aspect to be examined in the DFD. In the structure, you will know the basic functions inside the diagram and the limitation will be uncovered. You must examine the broadness of the structure and you must determine the range of it. Broadness is talking about how general the structure is and the range is the distance between the general aspects of the diagram to the more specific structure. As I understand the question, I formulated an answer with two points. The first point is the physical characteristic of the DFD and the second is the logical structure of DFD.

            The first point is for the physical characteristic which is talking to the physical attribute of the diagram. When examining diagram, you must understand every symbols inside the diagram. Like the starting state, end state, all those process and other function inside the diagram which has a physical attribute. Physical attribute is what you see in the diagram and what everybody sees even thou they are non-technical people. Physical attribute is the first to be evaluated if I will be the analyst because physical attribute is the syntax of the structure. I can say that it is the syntax because if the symbol is not in the proper position then the diagram fails to serve its purpose because it does not follow what is proper. Like arithmetic function, if your syntax is incorrect then it will give you the wrong answer. In physical attribute syntax will be the first security for the correctness of the diagram. It must be evaluated to proceed in the next process.

            The second point is the logical characteristic of the diagram. When we talk about the logical characteristic, we are pertaining to the logical structure which talks about how we understand the process in the diagram provided. If we are finish evaluating the physical structure, the next security feature is to evaluate the flow of the system, data and every object inside the diagram. The example of a wrong logical structure is when you have a data let say a student data then it will an input data to the admin division which is incorrect in nature. Student is not related to the admin because admin and student data is different. We can say that the correct interpretation of a logical structure is that the subject will be an input of the student which is enrolled to a different course. I must say that evaluating the characteristic of a logical structure of DFD is the difficult par. Logical Characteristic is not visible to the human eye but it will just be visible if you will analyze and understand the physical structure. In this level, the non-technical people will not be effective in this field. In the characteristic, it is more on understanding and not calculating. The said characteristic will be the life of the diagram and the physical structure will be the backbone. The logical will always be the brain of the diagram and we need criticize it carefully because the common problem of an analyst comes from this section.

            The physical and logical characteristic must work together. This two are the one who made the diagram possible. In the human form, the logical characteristic will be the brain and veins or maybe the soul and the physical characteristic will be the bones and muscle. The physical characteristic will hold the structure and prevent it from collapsing and the logical characteristic will be the controller. The two are important and if something wrong with either of the two, the diagram will not work properly. For me, physical characteristic is almost visible for everyone because in this area, you have clear guidelines and you need a less effort and less thinking skill for this one. In the logical characteristic is a different story because you need to have more intellectual property which is the analization, critical thinking, good observation, and other property that require a large portion of the mind.

            The composition of a physical structure is those who are physically very visible in human eyes like the actor, the process, the system. It is noticeable and if there is something wrong, you can figure it out easily. In the logical composition can’t be seen because they just exist inside the physical structure. They seem to be visible because the physical structure allow them to appear like they are present outside the diagram but in the reality, they just exist inside the diagram. In logical structure, you can correct them using the physical structure. You can manipulate them using the physical structure. It is somehow confusing but logical structure is just an imaginary variable for me. For me, it is an object with an object that’s why they are hard to detect because they leave inside the structure.

In examining diagram, you must not always look in the diagram itself because another way to examine a diagram is to examine your characteristic. You also need to examine the one who evaluated and make the diagram to evaluate the diagram itself and the thing that you need to examine is the characteristic of the evaluator which is you, I and them. Your characteristic must not always be in focus about how beautiful and organize a DFD is but you must be focus on how it is related to the system. As a starter analyst, I need to set my mind on the goals of the DFD. This means that I need to focus on what will be the function of the DFD and not how beautiful it is or how organized it will be. I must stick on how it is related and how it describes the object which is the system. Focus is also a good characteristic of an analyst when evaluating DFD because if you are focus enough, you can’t be destructed of how the other sees the diagram. You will not be affected of the comments of your co analyst but you can always use their words. If you are also focus, your decision will be more concrete and accurate hence accuracy is a very important thing that the analyst must have. For me, to be focus is an occurring event and my focus is dependent in every situation. Sometimes, I lose my focus when I am not interested of what I am doing. I also lose my focus if something is destructing my way of thinking like problem that I encountered during class hours or having trouble outside with my friends. I need to get rid of it when someone or something is destructing my way of thinking.

            Another characteristic of an analyst must have when he/she will evaluate diagram is interest. In evaluation, analyst is not effective if they lose interest. If they don’t like the things that they are doing, the percentage of making the evaluation right will be going down. Interest is a powerful characteristic because if you will have lots and lots of interest in your field and the things that you do, you will make it sure that you will do it right. You will never allow yourself to lose focus and you will be happy of what you do. Interest push the analyst to their limitation and surpassing limitation is a key for progression. You will be more effective if you will always do the things above your limitation and is a sign of a good system analyst. Interest will not assure you of making your work done with one hundred percent accurate but it will help you to make your work done with all your best. Interests will always guild the analyst in a right track in evaluating DFD. Doing things without interest is not a characteristic of a good analyst in evaluating the diagram but it will just make the analyst to be like a robot because robots have no emotion and they are always be in their level as the programmer programed them. I do believe that interest must be included in the characteristic of a good analyst because if not, that analyst will not accomplish something or not satisfying the needs of the client. If you will be interested in evaluating the DFD, you will be more observant of every detail in the diagram. You will not be hasty to give your evaluation because as I said, you are interested and interested people will show interest to their work and give an extra effort in evaluating the diagram.

            To be an observant in every details of the diagram is another characteristic of an analyst. This is important in evaluating the diagram because if you will be observant in every details of the diagram, you will discover if something is not right about the DFD structure. An observant characteristic will unlock those unseen error and it will provide the analyst a vision of correctness. Accuracy will not be a hindrance if an observant characteristic will flow inside the attitude of an analyst. A keen mind widens the perception of an analyst in examining the diagram and the wider the vision is, the more effective the diagram will be. Another advantage of a good observant is you will never see the diagram as a general concept or general system hence, you will see a variety of different structure and different interpretation. Seeing a different structure in a diagram will make your evaluation to be more flexible because you will not just evaluate it as a single structure but you will also consider those variety of interpretation that my come up during the evaluation time. If the analyst will observe that the diagram is in general form, by the power of the observant mind, he/she can turn the table and make it to be more specific and accurate in describing the system with the use of the proper diagram.

            Correctness is a characteristic of a person which assures all things in accurate manner. Seeing and evaluating diagrams doesn’t mean that you will just observe the diagram itself.  Before and after the diagram is being implemented, you must check the physical structure of it. To see is to believe and when evaluating a diagram, if the physical structure of the diagram is presented, you need to look at it and evaluate if the diagram provided is the diagram for the structure. In evaluating diagram, you must be correct always in your evaluation because your opinion is a crucial part of making a system. Correctness is a prevention of a further damage that may occur during the development of the system.

SAD ASSESSMENT 8

Journal SAD:Busy schedule + DRSUS

     This month is a busy month for me because of the paper works that is needed to be written. Number one of this is the SAD project and we are sacrificing the weekend just to make projects. Another is in the multi media project which is the Audio Visual Presentation (AVP) of the usep which will be pass on February 3. Today is a holiday because its a Chinese new year and suppose to be that this will be holiday but again, we need to take this day to make recording for our multi media. I am also researching for the Android structure as an assessment for the Operating System Subject which will be pass on January 31 at 5 pm. The thing is that i have a hard time to start it because I'm thinking that the twenty source from the net is not totally reliable. I have a hard time to search for the source because the common thing that i can found is about the coding and the general structure of the Android. Our teacher told us to try the book from the library that she requested but we found nothing when we go there. I need to scan the notes in OS because this Friday, we will have to take the exam. It compose of multiple choice which seems to have no answer(LOL)..Another thing that put my mind into pressure is the project proposal for the CS research. I think a lot of topic but it seems that the topic i formulated was not visible for my skill. I want a topic that i know i can do it and it can be made with in one year. The last issue that makes my mind pre occupied is the issue about the DRSUS.
 
       The senator create a bill which i forgot but the thought is that the 5 university in region X1 will be merge as one. The USEP earn its title for the past decade because of the people behind it. USEP is on of the university that provide a good quality education with affordable price. The purpose of the bill is to resolve the budget issue for the government universities. If this bill will be approve, the name USEP will be history and we    now start from beginning. One thing that i hate most is that the people behind the didn't inform the public especially us students about the benefit of this bill. The officer of the university is trying to contact those people  but according to what i have read in one facebook page that the people behind it is very busy like doing a ribbon cutting. I wonder if they study this bill well and i also wonder is they conduct a SURVEY to the people who will be affected to the bill. I really want to say in the face of those people if did they enroll to the subject like system analysis and design that every move like they did must be study first and they need to survey first before doing something. One thing that make this government a zombie because some people don't have the proper mind to thing and voice to be heard. To all people out there, i want you to know that we suffer not because of those greedy politicians but because of the brilliant voice that remain in silence. Yes, i'm pointing my fingers in your face. Shame. .....

Journal : Yesterday, Today and Tomorrow

      Last Thursday, me, Brian and Kevin went to city hall to send a letter asking for their system analyst and project manager. This is because our facilitator ask us to interview an analyst but the person we have interview didn't qualify for the requirements. After lending the letter to them, they said that they will just call us and after that day(Friday), someone call me that they have already read the letter and we can now conduct an interview. After that i take a bath, they call again and we can go today but after we get there, nothing happen and they said that the analyst is not there right now and we just go back to school. Saturday and Sunday is the day that we make our project and after making the project, we play games to get those stress moment out. Monday, we called to the city hall office and then they told us that the analyst is on medication and today, i called again and its all the same.

    Today, by browsing the net, a thought come into my mind. What if i will create a computer virus? after that i search for the virus and it caught my attention and i think its more interesting if i make one. Just for fun even thou its not a good act but the thing is i just want to learn. I will not do this because i want to heart people or piss people off but my interest push me to do it. I fount some serous virus that will destroy your computer and some funny virus that will restart your people. I just want to demonstrate it to my college friends. Tomorrow, i will try those learning of mine and see if it will work. The reason why i will not make today because im in my PC and it is dangerous .Im so mean T_T.

   

Journal: January 4,5,6 Class Report

     January 4 at 2PM, we started the discussion about the investigating system requirements. In the first reporter,  its very useful for me because it enlighten my mind about the gathering of data. It is useful when we are making our final project. This report is very critical because it tells about the correct approach when gathering data and one material to build a system is you need to have an accurate data gathering in order to make a good system. They also discuss about how to interview and what shall we do to be an effective interviewer when we want to know something about the information of a company. The things that stock inside my head about what the reporter told us is you need to have an eye to eye contact which i failed to do. Starting this time, i will assure that every interview that i will be make, i will try to look the eyes of the person who i am interviewing and try to show some interest. Be early in the meeting and don't let them wait and also, you need to shake his/her hands which i am shy to this.

   

           January 5, the next reporters topic are modeling systems requirements and the traditional approach to requirements. The reporter about modeling system, i really don't absorb the information that much. The traditional approach which i and Brian reported, is an approach in developing a system where you can only see the process and procedure but you cant see how the system does it. Some implementation of traditional approach is the dfd or data flow diagram. In DFD you can see the flow and structure of the system. Basically, by just looking in the diagram, you will know the limitation and the flow of the system. For me, its a simple way in showing the system structure to those people who are not deeply a technical person because its easy to understand.

          The last report is all about the object- Oriented Approach to Requirements and Evaluating alternative approach to requirements. Object oriented approach is a good approach when developing a system. It is more accurate method for me because the user will know every process and execution of the system. I also learn that we need to find alternative approach when developing a system and don't rely on one approach. It is more effective if you will combine those approach for a better output. We are currently developing a system right now and we are planning to use the traditional and small part of an object oriented approach. 

journal: Xmas(2011) and new Year(2012)

       My Christmas is a typical Christmas of a Filipino people. The difference between the last Christmas and new year is that my grandfather and grandmother are having a visit for a very long time here in Davao. I thought that the last time they visit here will be the last time that i will see them but I'm wrong.

      This Christmas, i failed to complete the "Simbang Gabi" tradition that i have consecutively completed for about 5  year straight. In the first day which started at 16, i try to get up and go to church but in the succeeding morning, i never thought that i cant get up because i am exhausted making the assessment in one of my subject. Starting that day, i never get up early and decided that i will complete it next time.

      This New Year, we celebrated it without a fire works. The city government mandated that no firework is allowed for the safety of everyone. To insure that all people in Davao will be caught because of violating the fire cracker ban, The Mayor and Vice mayor will give a reward for those who can point out someone who violate the rules. This rule is annoying from the start and its been 10 years since the mayor started it and we are now enjoying the benefit of fire cracker ban. You are not allow to burn your money anymore and for that, every body is happy.

journal 12/16/11 to 12/23/11

          Decemeber 16 2011 about 10 in the morning, i call the office of Pag-ibig Fund to follow up our approval letter for our final project in the SAD subject. The one who pick up the phone is the secretary of the manager and she said that she will pass me to Sir. Yan-Yan. Sir Yan is the administrator of the System and we had a talk that they can't approve our letter because they don't have the power to show it up to us and if we need to know the system then we need to address it to the main branch which is located in Luzon. Its very  depressing in my part because its a Christmas break and we can't write another letter for another company but then I tried to find another way to adopt that company. I tried to explain my side and i said that we don't need to look your system deeply but our job is just to know the process and know the flow of the system. We just need to study it and develop it to enhance the capabilities of the system. At that moment, sir Yan get my point and he said that they miss interpret the letter and he said that we need to go to their office at monday morning. As we said goodbye and starting from that moment, i know that we can now begin our study to their system and after that, i went to the school and tell my group mates the good news. We are now confident that the letter that we sent is being approve and we are very happy.

december 19 2011, Kevin which is one of the group and i went to the company. Brian, one of the member is not available at that moment because they have a party  and for that, Kevin and I face sir yan yan at his office and he is very nice guy. We discus some matter about the system and he told us the background of the system and its purpose. In short, we had an over view to the system and in a very first time, he tour us to the department and we had a good time. After Sir yan told us the over view of the system, we left the building and we promise to come back tomorrow for another discussion. When we arrive at the school, there is an even that is being organize by the nograles scholar. We participated the program and we had a great day all thou its a little bit stressful but we manage to go home alive.^^. we also tell brian about what happend and told him about what we had discuss in the office of sir yan. We had an agreement that we need to come back tomorrow at 9 o'clock in the morning.

December 20 2011, at about exactly 9 in the morning, Brian arrive at 9:30 in our meeting place and Kevin arrive at 10 am. Wew, labad....After Kevin arrive, we directly go to the building and we introduce Brian to Sir Yan and after that we had a tour again and this time, Sir Yan tour us inside the workers disk. He explain the purpose of every system and he introduce me to the Vice manager because the manager is not available from that moment because she has a tour outside the city and she is in the Manila at the moment. After the discussion, we had a snacks at the top of the building and Sir Yan is the one who brought us Shiopao and Coke. He is very generous and we learned so much from what he share. After that, we tell sir yan that we will come back at the second week of january and then we said goodbye and left. After that visit, kevin and i went to victoria mall for some other business and Brian went home that time. after buying snacks at the mall, we left the mall and go home.

december 21 ,2011 we went to the Digital Interface to interview their system analyst but sad to say that their system analyst is seek and he is not there. The employee just give us the number of their office and she advice us to call before deciding to go to their company. After that, we decide to go to the City hall to find another system analyst but the personnel tell us that she need to have the permission of the school and for that we decided that we need to work this out in school days because our teacher and the dean are not in the school because they are in the vication.

december 23 ,2011 , i call the Digital Interface about the update of the letter that we left about the system analyst and she just told us that he is not present at the moment and maybe we can call again at 27 of december for the update.

Assessment 6

            As what we obviously notice between systems professional John Juan and the department manager Peter Pedro is they don’t agree about each others opinion. When we talk about the position of the two, Peter will have in the higher position but it doesn’t mean that this will always be follow and in the case of John, he is an expert in this field and he knows how to handle the situation more than anybody else.

            If ill be ask on which side I will be between the two, I will be in the side of John because for me, he is the expert in this field and he know something more compare to the manager but its hard to pursue your opinion if the manager didn’t agree about your opinion. The best move they need to make in the first place is they need to analyze on what is the best to do. In my opinion, they need to study first the system to come up for the better approach because as I notice about Peter, he just base his idea in his past experience and for me, even thou you are experience enough in as certain situation, its always be a better idea if there is a study involve.

            First thing to do in this situation is to talk and understand each other because I believe that everything can be solved in a better and calm conversation. Conversation is a very powerful tool to communicate and understand each and as a result, they can come up for a much better idea than before. In the opinion of John, he has a point because he said that first, they need to examine the old system for the possible solution so that they will have a faster and effective solution. If they can enhance the old system, they can minimize the cost of operation and the workers can easily understand the system because the old system which they use in the past operation will just be an enhance version of today’s system. Because of the enhancement of the system, the workers operation speed will just be the same or maybe it will be faster than before because we can’t say that the workers operation speed will slower because we need to understand that its an upgrade version and they will make it better and easy for the worker so there is no room for the slow speed operation but going fast. The negative side of John’s opinion is that you need to study the old system and the worst part is you can’t come up for the better result. If that will happened, this reviewing of document will be a waste of time. I say that this is a waste of time because there is no useful data and output but still in my idea, its better to re-use the system to maximize the use of resources. Observing the workers work will allow the analyst to know the problem because sometimes the problem is not in the system but sometimes its about how the worker handle the system. The good part of observing the worker is to know how they handle system and if you will find out that the problem is the worker then you don’t need to re construct a system but you just need to teach them how to use it but if they cant really handle it because they have the hard time understanding the things in the system then you need to re construct the system again specifically for them to use it correctly and minimize the possible mistake they can make. John also give his word that he will assure to the manager that the previous result will not happened again and for me, if the people will tell you that, its almost a hundred percent sure and it includes their integrity as an analyst. He also assure that they will study the system and a assure to have a better understanding about the working an not working system.

            In the Peter side, he always want a new system compare to the modified system that may have less cost compare to the new system if you build. If Peter will finance the system development then we can consider it but if the company will finance it then it’s another issue. For me, an enhance version is not that bad if it will work like the new system but the good side is you don’t need to spend much compare to the new system but there are also a case that a new system is much better to the old but upgrade one because the cost is higher or the same compare to the new system and if that happened, it’s a practical choice to choose the new system than the upgrade one. That’s why we need to study the system first if we need to upgrade it or to renew it. Analyzing the cost, time, problem and the complexity of the system is the first things to do in order to evaluate and make an accurate move in a certain situation. As I read again and again, I found out that the manager has made up his mind and go for the new system because of what happened in the past.

            If I will choose between the two and if we weight the situation, we can see that John has a point and the idea of John must be follow than the idea of Peter. Let us first see the point why I choose John than Peter.

            First point why I choose John is because john is using his mind and Peter is using his experience. All thou experience is the most important than knowledge but we need to conceder that John is an expert in the system field. Peter is just a manager and comparing the right of the two, John must have the favor because he has the knowledge. In decision making, we need to be knowledgeable to a certain matter to have a better output. Everyone of us have expertise in a different field and if you’re an expert with that field then the chance of making something inside that field will have a greater chance compare to those people who are not expert. Second is that he applies his learning about how to approach the system. He wants to study first the system before doing anything and that’s a good idea. He is not concluding and he is using his head not just for his benefit but he is also thinking about the company and the cost. In every approach of developing a system, I must say that the first to do is to study first to know what to do and to have a better approach because approaching and developing a system must be study first to minimize the error and the problem that may happen. This will insure the success of the development so that the time and money will not be wasted for nothing. It can also minimize the cost because if there is a less error then less maintenance and as a result, you will have less cost. If you will study the system, you can balance the pros and cons of the system and for that, you will cover all the negative side of the system. Studying an old system will also give you an idea and build a much better system. If you cant enhance your old system because of some reason, you can develop a system which is far better than before because you will never do the same mistake again from the past system. Because of studying and analyzing the old system, it give you an idea on how to improve the current system and the old system will be your bases or your data for your new system. I am emphasizing the benefits of analyzing and studying the system first especially the old one because in this method, you don’t need to analyze a new system that much because the old system will give you a better idea on how the things work and how did they make it worst. The third point is about the cost related case about developing a new system or preserving and enhancing an old system. John is an idealistic person and for me, it’s a good attitude especially if you are an analyst and you are ask to build a system. If you notice that sometimes, preserving the system that function properly and enhancing the old one will cause you less compare to the new system. It is not like upgrading your computer by buying another tool that enhance your computer or buying a new and upgraded unit. In the system especially if the system is big and complex, its more practical if upgrade it than getting a new one. Like for the case of Pag-ibig Fund in Davao City which will be the subject of our final project in SAD. The style of their system is they just upgrade it and enhance it because if they will go back to the top, they will spend another time to teach the worker and for that, it’s a time consuming and time for them is very important because every second counts. They have 29 or something branches all over the Philippines and if you will have the new system then all of the branches will suffer the consequence of the new system. Their style is in their branch, they study and enhance the system for further development and if they come up for a new system then they send them to the other branches and deploy them to make the system upgraded. They re-use the system so that the development process will be faster compare to the implementation of a new system. The disadvantage of a new system is they need to have more maintenance compare to the old one. In my own opinion why the new system have more maintenance because they are new and it’s very difficult to perfect not like the old one because they have proven and tested for the past year. In a relation of perfection, there will always cost involve because in order to perfect the system, you need to study and upgrade it and it will be costly in the part of the employer.

            In the last word of Peter, he sounds like he doesn’t want to cooperate. He just wants to do what he wants and doesn’t want to talk to John. This action will develop conflict between the two developers and will never have a good output. Team work is very important and I believe that two head is better than one. If I will judge the moral of the manager, he will not be permanent in this business because there is a roughness in his attitude and it is not right. In that case, he is prioritizing his personal opinion and doesn’t want to listen to others opinion. As an analyst or a manager of the company, you need to listen to other’s opinion because your opinion is not always good comparing to others opinion.

            If John’s opinion will be follow and prioritize, base on my opinion about what will he do about the old system is to find out the useful one. The useful one are those program and system that is not necessary for a change. If you will replace the useful one with another system then it’s a redundant plus it’s a waste of money and time. Even thou the new system will function properly but then the old system which is functioning perfectly will be wasted and the worst part is if the new system will not function properly then you need to fixed it or enhance it to meet the demands. After evaluating the system then maybe if there are no more enhancement and development needed, you can start creating a new system.

            In the assessment five, we are ask to search for a system development method and one of the method that I have learned is the Prototyping method. Prototyping method is a good method which is flexible enough in every system. The style of the prototyping method is building a prototype system and they put the prototype system into test and if the system is somehow perfect then they build a system from the prototype one. It is very fast and effective because in the prototype, they build the system in a rapid manner. It is sometimes called a rapid development which I have learn during our class in the data base system. Rapid development because of the short amount of time in developing the system.

I would like to discus first about the prototyping method for my recommendation for the development process of the system. We need to admit that in every method, there is always a negative part and one negative part of the prototyping method is it has a low security measure because as we all know that it is being develop in a rapid manner and it is tested with trial and error in order to perfect the system. If this method has the negative side, it has a big advantage in terms of time and cost. You can save time if you will have this method because as always saying, it is a rapid development. For me, time is very important because every minute count in the business. Every minute is always equal to profit and we need to give value for it. This method is also a less cost effective because you don’t need a long period of time and if you will have the shorter time to develop the system then it is a cost less system.

For me, this prototyping method is very much effective in terms of quality, time and cost of the system. If John’s idea will be prioritized then I must require that he need to use this method and it is very suitable for the situation. If my idea will be follow, I will use the old system to the prototype system and then I will study the system. When you have a prototype system, it is easy to re develop the system that is very friendly to the worker. As I have known, even if the system is almost perfect but then it failed to do its work because of the workers. The workers are the one who is making mistake and for that, the system fails. If we build a system, we need to think always about the workers on how they react or use the system. Even if your system is almost perfect, this will be useless if the worker will just destroy it. In the other word, human error is evadable but we can always reduce that human error in the system by having them connected to the system and by making them understand and making the system to teach them. Structure is very important like security because structure will help the user to understand what is need to do and what is not. As we go back to the statement of john, he wants to study first the system and separate the usable system from the one who need to upgrade or replace. If that what he want then if you use the prototyping method, you will notice if what the system is needed to improve by the use of old system as a prototype system. You can adjust the system for the workers and it is easy to perfect because they will always test the system until you will be satisfy. This will also determine if the system has needed for the replacement if you will see that the system is not meant for the worker. Systems are created for the worker and to address the problem of the community.

There are different reasons why I choose prototyping method and for me it is very effective. The first reason is about the system can be upgrade and the old system can be upgrade and this is the perfect time for the prototype to do the work. If you have this old system then you need to use prototype to determine if its upgradeable or not. I can say that this method can satisfy the worker and the manager because it will have the quality of a new system or better. When the old system will be using a prototype method, it will match the need of the worker and that’s the important one. Another reason is that this will minimize the time consumption especially when you are in a hurry. This will cover up the time that is being consumed by reviewing the system because reviewing the system which is the idea of John will consume some time and because of this method, you can cover all those time.  After the reason for the time, another reason that I really want to emphasize is the cost. As I have said earlier, Peter is seems like he doesn’t care about the cost compare to John which is concern about it and also an expert in the field of system analysis. If you will use this approach, you will save money because it is not costly compare to another method. It is a good approach especially if you will make a huge system. We need to control the cost that is being use in development because maybe sometimes we need to spend that money in the other side of the system.

If someone will question why I choose this method and why waterfall method which happened today because someone in my classmate ask me about the method then I just answer them that in my opinion, waterfall method is good because it’s simple but its not flexible enough when you use it in different system. The problem is that you don’t know how complex the system is and if you will choose a method then you need to be sure that it can cater the entire possible problem. The waterfall method is only useful if it will be use in the simple system but it is impractical when you use it to a much bigger and complex structure of the system. We need to assume that all system can be a simple or complex one. If you will always focus and will not think about the possible structure then this may be a case that you will fail to do your system. I think also about the possible action that can be made by John which is reviewing the system and for that the method prototyping will do the work for an easy system.

I conclude that we need to understand each other especially if you are being ask to do such thing and we need to have team work every time because two head is better than one. We need to think first before doing something and experience is not always the key to success, we need also to use our brains and lastly, conversation is a powerful tool and we need to make use of it always especially if you have quarrels..

Assessment 5

Consider your school, how do you know that the life cycle was developed specifically for the university. How do we know it meets our needs? 

In every system, there will always have a life cycle and we need to know the life cycle of a system to have a better understanding about what the system is all about. System life cycle is an entire process of a system at the beginning and ending of it and it involve development process and stages.

Every stages of a system life cycle is crucial and important to development and we need to know it in order to have a better understanding to the cycle on how it begins and how do we end the system. System life cycle will determine the flow of the system and in the flow, we can see how the system works and how it will affect us and the system. We need to study and analyze the steps because if we don’t know how the system flows, the system will not be effective for us because system life cycle is needed to be follow and if we didn’t follow it, it will bring problems for you and for your university or company. The system life cycle can be a guide for us in order to have organization and it will tell us what to do and what steps are to be follow.

            In a life cycle, we will know if that cycle is developed specifically for us if this will address all the problems and all the process in it will flow smoothly.

Organization

            We will know if the system life cycle will be suitable for us and for the university if it will make the university to be organized in every aspect and every corner of the university. Organization is very important in every aspect of the system and it will also give the university a smooth process and it will minimize the error and problems that may be created during the deployment of the university. In the beginning of the creation of life cycle of a system in school, we need to include and address the organization of the system. If you will not address the organization of a system or you will not give time to improve the organization of the system then it will not be effective in a long run. If we notice in the school enrollment system, you will notice the organization of it even thou it is not perfect but it can accommodate the students need because it is organize. Every process in enrollment system is being analyze and tested. I can say that it is very effective and I notice that the work and process is being sub divided to accommodate and address the problem. The university has registrar, advising, encoding, and payment process. The reason behind this division is to organize and the system life cycle. I want to make the enrollment system to be an example of a good system that is being organized effectively to address the need of the university.

            The first process is to have the advising process and it is being done in every department. If you will make the advising process in one room or one office, there will be no organization at all because in not all the student is enrolled in one course. The person or group of people that will advice the student will have a confusion because in every student have different problems and that problem is not common for those people who are not working and handling the college. The result of that process will not be effective and will affect the performance of the university. As I notice in every college, not all colleges have the same process in advising like the literature student. They need to have an average of eighty five percent for them to continue studying in that department but compare to the institute of computing, they just need to pass all the subject in the current year level that is being provided by the college curriculum. They don’t need to have an average grade of eighty five percent but they just need to pass it all. In advising, students have their personal concern or problem that only a specific person in the college can answer. After advising, you need to encode your subject to the encoder and the encoding process can be done during the advising process but in my observation, encoding and advising must be done in separate way is to make the adviser to focus to their advisory and to make the adviser’s work as convenient as possible. The more system is being sub divide, the more it will be organized. After advising, you need to have payments to pay for the subject you have enrolled. The payment process is very sensitive because there is money involve. They make it as one of the division of the system to protect the payments of the student. In the casher, all the payment is being process to organize the payment system. If you will have different payment in every college and it will be made in there college, the worst about this structure is that it will create a redundancy process. It is more convenient if the payment will be made as one to organize the system and if this will happened, it will be an impractical way and process the university has made. In this one process of the system, the payment system is made by one division and for that, we can say that this one part of a life cycle is being made specifically for the university because not all university or company has this process and I know someone out there has different structure and approach because that specific approach is being made for there system life cycle. Registrar is the last phase of the enrollment system and this will make you a certified student in the university. If all the process will be done in the registrar, it will be a long process and it is not convenient to us students and for the employee of the school. The life cycle must make the system more convenient to all to call it as a good life cycle and to prove that this system if made especially for the university. Even thou we can’t prevent the delays and the slow process sometimes but its better to have that organize process but not perfect than no organization at all.

Integrity

            In every life cycle, you need to insure all the process liability and integrity of a process. You need to make sure that all the transaction is being validated to have integrity and if there is no integrity in the life cycle in the university then this is just mean that this life cycle that is being develop is not meant for the university. As I understand about integrity, it is always talk about the validity and security of data. Validity is to insure that all the data is correct to eliminate error from the life cycle. If the integrity of the data or information is not valid or corrupted then the system life cycle will not be follow correctly. There is always an instruction and perimeter to be follow in order to have integrity in every system or process. In the side of security, it will protect the data or the process from being contaminated. We need to have security always to insure that everything that we handle are secure so that we can minimize the error that may be created as possible. We can’t rely in every process or cycle that has no integrity because it will ruin the university or company. A corrupt process or system can’t function correctly and for that, the output of all the process is not what we are expecting. You can also implement integrity by having organization to tighten the security. If we make our university as an example of a process that implement integrity, the basic example is the guard and the student wearing their identification card so that the security guard will allow them to enter. In this case, there is Integrity because the security guard asks for the student identification card to certify them to be a student of the university. This will secure that all student entering the university campus is a student from this university. Another example is in the subject advising in the enrollment process of the university. Before encoding of subject, the pre-registration form must be sign by the adviser before it will be encoded. That is a sign of security and validity because this will insure the integrity of the date and the person. If that perimeter is being applied then we can say that this life cycle is being developed especially for the university and on how I observe the process to insure integrity, I know that this is really intended for the university use even thou not all the process in the university is secured and validated like the signing of clearance. I know that some people have an unauthorized signing of clearance which they sign the clearance without permission and the don’t have the authority to do that and the security and perimeter in this area is not yet develop but still it is not always the bases to say that the system life cycle is not intended for the university. We need to consider the general form of the life cycle of the university to validate if it is made especially for the university.

Synchronization

            We can say that the system life cycle is intended for the university if the process is catering the needs of the university. In every university like my school or every company has their own life cycle and every process must be connected to the service that is being provided by the university. For example, you need to enroll in the university but the university doesn’t have the enrollment system. In order to have a university, one requirements is to have a population and if there are no student population in the university then it can’t be called as university anymore and that kind of system is not intended for the university because it doesn’t cater the service and needs of the university. For me, that’s the obvious evidence if that life cycle is not intended for the university because the process and services is not talking to the university needs and services. One characteristic of the life cycle that is being developed for the university is it provides services like in the university enrollment system or human resource system. System must not only for decoration but it must be functional and it caters almost all the problem and requirements of the university. If it will not provide almost all the services of the university then I can assure that this system is not for the USEP.

Instruction/Guide

            To insure that the life cycle is develop for the university if the instruction or guide is match to what the university service and process must have. If the instruction or guide is not match to the university life cycle then it is not intended for the university. The instruction and guide lines must produce a correct output. For example in the university, the life cycle has the instruction about the enrollment system that you need to advice first before encoding. I made the enrollment system which is one part of the life cycle of the skill as an example because it is common to all the university. Instructions are need to be follow and all instruction must match to the specification of the school service. If the instruction will not match to the system of the school service then it implies that this is not meant for the university. If the instruction will not be follow, the possible problem is that during the process, the data will be invalidated and the process will be frozen. If that will happen, there will be no process, development, input and output at all. All the system will be paralyzed and for that the life cycle will not be functional at it will imply that this kind of life cycle is not intended for the university.

Development

            Development is another way to find if the life cycle is intended for the university. Even thou it seems that the life cycle is functioning properly and doing its job but sometimes we need to watch the development and progress of the life cycle of the system. For me, we need to solve a certain problem that may be encounter during the cycle and it is not all about repetition of a process over and over again but there must be a progression involve. The development will measure on how effect the life cycle will be by the amount of development in the life cycle. If there is no development then you can conclude that this life cycle is not meant for this university or company. For that, you need to change the life cycle structure to address the problem in terms of process and service of the university. The life cycle must include development process in order to make it effective and uniquely develop intended for the university.

How to know it meets our needs

            Needs are those important things that we need to have. In the university, the needs of student are those requirements that they need to have in order to pass in a certain subject or it can also be in a form that the student must be enrolled or another example is the requirements to renew the scholarship from Nograles. We need to have that because we are required have it as part of our duty as a student.

 We can tell that it meets our needs by showing us the possibilities that this certain needs are possible to achieve in an organize and simple manner. It must address and fixed our problem as a student and if the system can satisfy the student then I must say that it meets our needs as a student. The only way to know that it address our concern is it must provide solution because the life cycle is not only a process but also a solution to the problems and complains. I want to make the enrollment system as an example again on how did it meets our needs as a part of life cycle. In enrollment system, the school provide an adviser in every college to advice the student in the subject and enrollment matter, they provide encoder to encode our subject that we will be taking, they provide cashier and students account to handle payment, they provide registrar to validate us and register us a certified student of USEP. All this process provides us a way to be able to enroll in the university and for that, it provide and meet our needs to enroll. All those process are instruction that allow us to be a student and validate our presence in the school.

            I conclude that we need to have an effective life cycle because this will be the instruction that will lead us for the success not only for ourselves but also for the university. Without life cycle, there will be no progress and there will be no life at all. I must say that this is the heart beat of the university, company and other organization because this will determine if that certain university or company is alive or not.
