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. .....
