ABSTRACT

We selected a video/Game rental system of the MAX SOFT DVD/CD VIDEO AND GAME CENTER. The manual system that existed to mange the rental system did not meet the user requirements. In our automated system we computerized every bit of the old manual system of borrowing and returning of videos and games. Our computerized system we implemented in the video/game center helped to reduce the wastage of paper and documents. Also it helped to minimize the space required to keep the records giving more space to the business.The system we introduced is user friendly and easy to use so that even a person who has little computer literacy would be able to use the system. This would help the business due to the reason no training will be required to use the system, so that it will not cost anything to train the workers. Also we hope the newly introduced system will increase customer satisfaction, worker satisfaction and profits to the business.

1.0 INTRODUCTION

We chose MAX SOFT DVD/CD VIDEO AND GAME CENTER which is situated in kirulopna,Colombo to implement our system. MAX SOFT DVD/CD VIDEO AND GAME CENTER is a medium type business which was started 2003. We used to go there to rent videos. We chose this business because we already know the manager and the workers very well and we our selfs as customers have undergone the difficulties of the manual system they have. When we went to the store as system analyst we noticed several problems in their current manual system. After observing for several days how workers operate and how customers behave, we interviewed some customers and gave them a questioner to fill out. Computerizing these data we designed a new system fully automated renting system which will increase company efficiency and also customer satisfaction.

1.1Company profile

MAX SOFT DVD/CD VIDEO AND GAME CENTER is DVD/CD renting store that was started by Mr.Hasitha perera in 2003 which is situated in kirulopona, Colombo. When it started only two employees were there to manage the shop. The owner of the shop had several businesses running. These two workers maintained the records and handled the customers. Because of that business had some problems with the records and customers. Currently they are having five workers and still they dont have an automated system running in their system.

1.1.1 Company VisionTo be the leading multimedia partner of Sri Lanka

1.1.2 MissionOur mission is to provide our customers with the best multimedia experience that they can have from a vast variety of entertainment methods uplifting their lifestyle and making their lifestyle more enjoyable.

1.1.3 ScopeThe new system we introduced to the company has the latest computer equipments. By using the latest equipments it will speed up our system and it will help to take an accurate, reliable and timely output. From the new system we are implementing on the company it would handle most of the operations done manually in the present. Our main goals from this system is to reduce customer dissatisfaction, increase the profits of the company and to create a better image of the company.

2.0 Systems Development Methodologies

Why does a system need methodology?

A System methodology is needed to control the process of the performance, and manage. And also by using a system methodology the time and the cost are reduces. Mainly the employer can interact with the staff by if a methodology is used. User is encouraged to involve in meeting the user requirements, and the quality of the work is also improved by using a system methodology.(Nadeera , 2010)

2.1 Use of Methods

There are four different Methods. They are: Prototyping Object- oriented Analysis and Design (OOAD) Rapid Application Development (RAD) Joint Application Development (JAD)

2.2 System Development Life Cycle

The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. (Anon6 2010)

SDLC waterfall model methodology

System Development and Life Cycle (SDLC)About the Function take place in Current System

As in the moment this is the most famous and biggest Video center of this extent, which gives the entire customers an opportunity to easily search and find any film by any main language, and also making it a lot of easier to find different films in categories chosen by age, as there are more than 2000 movies, also range of a huge variety collection of music, MP3, CDs.Work StrengthCurrently there are five helpers involved, - one cashier who is taking care of the accounts, and the proprietor who decide and determines it all, example: who made the group, subject of it, and who choose the members. Others help the customers who want help in finding films. And also they help with the cleaning in the company.Technical StrengthAt the same time they are using two DVD players with monitors and two computers. One is utilized by the accountant/cashier, and one to control but also check the returned CDs and for evidence. Available items They rent out Movie CDs and also they sell VCDs and DVDs. The CD center has a large Varity of English movies compared to Hindi, Sinhala and other language movies. They dont have TV series collections. Techniques Used in current system They use a manual data entry system. They keep a book to store their information and they use Microsoft Excel to keep a data backup in a computer. Existing SystemFirst customer has to talk with the workers to find his required film. Either a worker or the customer himself has to find the film from the shelves. When the customer found his film the customer have to provide his registration number and his NIC to the workers. This is to provide security. Then he has to pay the amount he has to pay for the rent. He has to pay a deposit also so that he cannot commit fraud by not returning the movie. When they are returning the movie the customer have to provide his NIC and the registration number to return the film. The worker has to enter the details of the customer in the book and also in the Excel document. Identifying Problems, Opportunities and Objectives

Problem Identification Status of the rented CDs which were returned are bad. Customers do not have a direct contact with the company. So the shop has difficulties in contacting the customers. A customer does not return the CDs on the due date. New arrivals(films) are not properly ordered and details of those are not entered into the system Data recording method in a book is a very bad way. it is hard to find CDs/DVDs when the customer wants. No specific method to collect fines from the customer No proper secured system for the collected data.

Opportunities If we implement a new system to handle the video renting and selling, its going to be easy to check the availability of a specific CD whether it is available in the stocks or whether that specific CD has been returned out, Via the system it will be easy to check that going through the manual procedure.

Objectives of the new system

People Involved A team is required to implement a new system. This team comprises of group leader, System manager, system developer. The people who are benefited from the system are the employees, employers and the customers.The information that is gathered about the existing system give a clear picture of what is required for the new system and its requirements. In to do one should be in contact with the persons involved in the prevailing system such as the employees, employs and the customer.

3.0 Feasibility studyThis is the first phase of the SDLC model. What is feasibility study?

An analysis of the ability to complete a project successfully, considering about legal, economic, technological, scheduling and other factors. Rather than being optimistic and just start a project, a feasibility study allows finding out the possible negative and positive outcomes of a project before investing too much time and money.

why we use feasibility study?

A feasibility study clearly specifies if a project should be preceded or not. So we used this study to predict that our project has a reasonable chance of success. The members mainly focused on four of the components of feasibility study. They are, Technical feasibility. Schedule feasibility. Operational Feasibility. Economic feasibility.

Feasibility of the current system:-Currently the MAX SOFT DVD/CD VIDEO AND GAME CENTER has a manual system to handle the whole procedure of the shop including money transactions and records about the customers and discs. All the transactions are entered in books by the employees. Unlike in an automated system, this method causes weaknesses in accuracy and efficiency very often.Feasibility of the proposed system.

We produced a fully automated system through Microsoft Access which is parallel to the current procedure of the MAX SOFT DVD/CD VIDEO AND GAME CENTER shop. It is capable of handling the same transactions and recordings reducing the weaknesses that the manual system caused. Because of that employee can easily enter customer details in few seconds. There for all the important data secure. Only few can access and handle the system, if there are issues of customer details or other things only those are responsible. Details which we enter to the system are accurate. Because of the new system it increases customer satisfaction, accuracy, secure and also the employee satisfaction.

3.1 Technical Feasibility

As the current structure did not have an automated system, our main intention was to implement a new system to this company which will enable to increase precision of their work. Initially we focused on the resources which are planned to use as fundamentals of the new automated system. It is important that these resources can be gathered on an affordable price with good quality.

The new system should be widely available. The main target of the new system is to make the work easy and enhance the efficiency of the employees. So it should be basic, easily upgraded and user friendly. The IT literacy is essential in employees because each and every task (money transactions, keeping records on the customers and the available discs, recording and copying the discs, etc.) in the system will be performed by computers.

Next we sleeked for the resources that are already available in the company and the capability of the current employees. There are two computers, including one that needs to be repaired. And most of the employees were capable of handling computers. Others were willing to learn the basics of computing and adjust quickly according to the new system.

Then we focused on the other essential resources that we should buy. It was revealed that we need two more computers, a laser printer, windows xp operating system, an internet connection and a four port router, so that we can connect four computers into the network, mouse, keyboard, virus guard.

3.2 Schedule feasibility

In the beginning of the project, the members should estimate the time period that will be taken to finish the task completely. It is better if each member has their own schedule, including the assigned work in separate steps and the estimated time for each small step. So the members should work according to the plan and always try to be above the schedule. In this way, unexpected delays will not obstruct with finishing the automated system within the proposed time period.

3.3 Operational feasibility

The PIECES framework can help identify operational problems to be solved and their urgency. (Nadeera.2010)

3.3.1 PIECES framework

PerformanceIn the current system workers have to enter entire data manually. Keeping records in books takes a long time and it is hard to ensure about the accuracy. The new program can handle the same transactions that were manually handled before, with more competence, while minimizing the errors because all the details about the customers and discs can be checked very easily in the automated system.

InformationIn the manual system, information such as availability of the discs is entered in books. So when it comes to a transaction, the employees should refer all the books to find out if they can fulfill the customers requirement. The same information can be checked through the automated system in a less time without any errors.

EconomyThe automated system directly helps to improve the economy of MAX SOFT DVD/CD VIDEO AND GAME CENTER shop. The possibility of losing customer with the manual system is higher because many errors can occur in every stage of a transaction. Holding the present customers of the company and attracting more customers can be only done by reducing these errors. Calculating fines and inefficiency in finding the availability of discs are two stages that make major errors that affects a lot on the economy of the company. The proposed automated system calculates everything more accurately and efficiently. This naturally increases the profits of the company. Even though a remarkable capital should be invested for this project, the company can cover up the cost in a very short time because of the good service that is given to the customer. Later on the profit which is gained through the automated system can be used to develop other sections in the company.

ControlIn the present system the data of the company are not secured. But the new system to be implemented by us is consisted of log-in password and username. So only the employee has access to the system. Therefore outsiders are not allowed to log-in to the system. So the security of customer details are ensured as long as the employees work with responsibility.

EfficiencyThe manual system uses only man power. It lacks modern technology. It is proved that using technology is always faster and successful than man power. Writing all the data and transactions in the books takes a lot of time and we cannot count on the accuracy as well. This kind of a procedure cannot cope up with the busy life style of now a days customers. Only a few clicks on the computer screen is required to deal with the new system. So much more amount of transactions can be done within a short period of time. The customers do not have to be kept waiting for long and it increases the customer satisfaction.

ServicesThe current system has many failures in providing information on availability and also being efficient in terms of time. Customers will leave the company because of taking more time to rent a video or return a video. Employees have to go through the record books and have to check the due date and if there is a late payment they have to calculate it manually. Hand receipt will be issued to the customer. With our new automated system employees will take few seconds to finish their work. It will count all the fines automatically and a detail bill will be instantly issued to the customer on demand.3.4 Economic Feasibility

Economic feasibility can be classified as two. They are:2.4.1 Cost Classification Direct/Indirect costs Fixed/ Variable costs Development/Operational costs Tangible/ Intangible costs

2.4.2 Benefit Classification Direct/ Indirect benefits Fixed/ Variable benefits Development/Operational benefits Tangible/ Intangible benefits Positive/ Cost Avoidance benefits(Nadeera. 2010)

Here we point out the necessary requirements to build our new system. Therefore it is our responsible to find out quality materials for the best prices.

Fact finding/Requirement gathering is the second phase in the Systems Development Life Cycle. And it is a crucial factor in a successful project or a system.

Figure 1 Requirement GatheringBefore building our system we had to analyze MAX SOFT DVD/CD VIDEO AND GAME CENTER from A to Z. It is a crucial factor in building a good system. We have to gather information to analyze. We can use various methods to gather information. Mainly we used four methods to gather information on the company.1) Sampling & Investigating2) Interviewing3) Questionnaires4) Observations

4.1 Fact finding techniques

4.1.1 Sampling & Investigating

The Need for Sampling.1) It will help to speed up the data gathering.2) It will Improve effectiveness3) It will help reduce bias - Kendall (2003, p.83)

The advantages and the disadvantages of sampling and Investigating.DisadvantagesAdvantages

More complex, requires greater effort than simple random; strata must be carefully defined (Anon, N/D Ref.002) Highly representative if all subjects participate the ideal(Anon, N/D Ref.002)

Not possible without complete list of population members; potentially uneconomical to achieve; can be disruptive to isolate members from a group; time-scale may be too long, data/sample could change. (Anon, N/D Ref.002)

Possible to select randomly when no single list of population members exists, but local lists do; data collected on groups may avoid introduction of confounding by isolating members(Anon, N/D Ref.002)

Can be highly unrepresentative(Anon, N/D Ref.002) Inexpensive way of ensuring sufficient numbers of a study(Anon, N/D Ref.002)

4.1.2 Interviewing

In a interview there can be two types of questions.I. Open ended questions II. Closed questions

In open ended questions interviewee is free to answer the given questions in any amount of words. There for the interviewee can answer with a peace of mind.In closed questions the interviewee is bound to answer the questions with a limit of words given by the interviewer. (Kendall, 2003)Advantages and the disadvantages of InterviewingDisadvantagesAdvantages

The interviewing can consume loads of time. The interviewee can clear out any doubts regarding the questions by asking out.

The interviews can lead to topics that does not related to the system or the company The interviewee is given the chance to explain his or her answer to the point

It is hard to select the best or the right people for the interview. The interviewer can observe the body language of the interviewee to detect false answers.

The skill of the interviewer is much needed to get the best answers from the interviewee. Interviewer can readapt the question according to the level of knowledge of the interviewee.

Interviewee can verify the answers accordingly to the interviewer. Interviewer can get personal opinions or information about the system from the user.

4.1.3 Questionnaires

Questionnaires are a much cheaper way to gather information from a large number of people who uses the system. (Kendall, 2003)Advantages and the disadvantages of QuestionnairesDisadvantagesAdvantages

People or the users lack of interest to answer questioners. Easiest method to gather data or information from a large number of people

Users can give fake answers without any trouble due to the fact some questioners remain anonymous. This method is cost effective due to the fact less amount of money is wanted to create a questioner and distribute it.

Have to create a questioner that is understandable to the users. This has to be done by a skilful analyst. The users can give their honest opinion about some facts which is about the company due to the reason some questioners remain anonymous.

Questions in the questioner can be misunderstood by some users and it will help to gather harmful data about the system. One can use other communication methods such as internet and email to distribute questioners and collect answers.

This method is less time consuming and questions are pre defined and will stay on the subject.

4.1.4 Observations System analysts use this method to gather sensitive data, by observing the decision maker and his behavior analysts try to gain insight knowledge about what is truly happening in the system.Observation must be structured and systematic if the findings are to be interpretable. (Kendall, 2003)

Advantages and the disadvantages of ObservationsDisadvantagesAdvantages

Observation takes lot of time to gather information Inexpensive compared to other data gathering methods.

People might behave differently when they are being observed. Analysts can directly gather information on how the system works in a wanted place.

Depending on the skills of the analyst gathered information can be differed. Analysts can easily get a better knowledge of the common operations.


After going through the requirement gathering methods we were compelled to make a choice of the above four methods. Observing the company for some time we decided to go ahead with the questioner and interviewing methods. We had several reasons to pick these methods.Our group consisted of three group members. The method Observation needs more than three analysts to gather information. We could have gone ahead with this method and collect lot of valuable information on how the company works. But we were on a tight time schedule due to that reason because observing method take lot of time to gather information. Also we notice that most of the workers and the customers didnt like to be watched. Company manager and the workers were friendly with us the whole time. Because of that reason we agreed on each other to interview the manager and the workers and some customers to get the information needed to build the system. Employees know the current system A to Z and were more than willingly happy to share their knowledge to improve the current system so that they can have much easier time at work. Manager and the workers were keen to let us know what improvements were needed in the system. Since there were only five workers and a one manager we created two different questioners. One was for the employees and the other one was for the customers. Customers were hard to catch, because of that reason we had to go there for five days to get hold of 25 customers. Most of the customers were teenagers and some were students of different schools. Some of the customers were above age 40 and they were not happy to be interviewed. As well as the interviewing method we went ahead with the questioner method. The main reasons we went ahead with this method was customers were happier to give information anonymously. And also it gave us a clear picture of the basic requirements what customers needed with a new system. We created a simple questioner with ten questions and it was distributed among twenty customers. Using the results of both methods we gathered enough information to build the system Questionnaire that was used to gather information can be reviewed in the Appendix area

Analysis of the results of the Questioner

We were able to distribute the questioner among twenty customers. Customers filled the questioner taking their time. After analyzing the answers we were able to recognize a pattern in their answers. We used a bar chart to illustrate the answers of the customers. According to the percentage of the answers we decided what we should consider mainly in building our system.

Figure 2 Bar chart of the answered questionerAfter analyzing the answers we were able to draw the bar chart shown above. In the y axis we showed the number of people who participated in filling the questioner. In X axis we showed the questions. We calculated the percentage using a simple mathematical equation.

Percentage = Number of people who answered No 100 Total number of people

We took each and every question analyzed them accordingly to the number.Q #The Question Analyzed Information

1Were you happy with the old system which was used up to this moment?25% of the customers answered this question agreeing to the fact. 80% of the 25% customers were above the age 40. This insisted the fact that older people was little bit backwards of the idea of using a new computer system. They were happy with old card system that is simple according to their knowledge. So we had to mark the point that the new system we are planning to build should be user-friendly so that the older people could easily understand and use. 75% of the customers said NO the question. We had to gather the reasons of their unhappiness of the old system. Most of the customers pointed out that it takes lot of time to burrow the DVDs/CDs. This was due to the card system existed in the company. Most of the cards were misplaced and there were no order of keeping the cards. Some of the customers said that it takes time to find their desired DVDs/CDs. Also customers told us the workers take more time when they are calculate fines. So we were compelled to find solutions to these problems in our new system we are creating for the company. We designed a new registry system for customers also for the workers. This would able to track the customers and their deposits, fines. Also a system to calculate fines and print a receipt of the customers renting or purchasing that took place.

2Are you happy with the condition of the DVDs/CDs?

70% of the customers said YES to this question. In the current system every time a customer returns a DVD/CD the workers are ordered to look at the DVD/CD to check weather it have any damages. If there is more damages in the DVD/CD when returned the customer are fined. The customers are always advised to check the DVD/CD before they take it out and show it to the workers if there is any damages in it. We were advised by the management to implement this rule in the new system.

3Are you happy with the Management?

90% of the customers said YES to this question. The manager in the company was friendly to the customers and were listening to their complains.

4Are you happy to provide information to be entered into the new system?85% of the customers was happy to provide their information to be entered into the system. Other 15% was not happy to provide their personal information due to the fact of security. We had to mark this point as a important factor. We were asked to secure the system from outsiders. We had to implement a secure login for the workers as well as the customers. Also the workers are to be accessed only the basic information of the customers.

5Would you like to have a secure login and an account for yourself?95% of the customers were happy to have a secure login and an account for them selfs. Most of the customers wanted to check their renting histories and their fines and deposits.

6Are you happy with the efficiency of the current system?Only 20% customers were happy with the companys efficiency. This was major factor we are advised to look into. The problems and solution for this was similar to the fact we gathered in the first question.

7Are you a visa or master card holder?Only 15% of the customers were equipped with visa or master card holders. We were asked by the management to check this factor. The management was planning to go online with their system so that the customers would be able to reserve DVDs/CDs online. Through their visa or master cards they would be able to pay the necessary payments. But from the questioner we saw that only few people are equipped with the cards.

8Is it easy to find the DVDs/CDs you want?40% of the customers agreed that it is easy to find the DVDs/CDs that they wanted. Other 60% of the customers pointed out that the reason that they said NO is because the workers them selfs didnt know where the DVDs/CDs are placed. In our system we had to introduce a numbering system of the DVDs/CDs

9Would you be satisfied if a new system was to be implemented?90% of the customers were happy if a new system was implemented.

10Would you like to receive a printed receipt every time you Purchase/rent DVDs/CDs?100% of the customers liked to have a receipt after they rent or buy a DVDs/CDs. So we had to add a receipt generating sub system to the main system. This is to calculate fines, total and change.

Analysis of the interview that took place We designed two interviews. One for the employees and one for the customers. We interviewed 5 workers and 25 customers.Interview that took place between us and employees Q #QuestionSummery of the Analyzed information

01How does the requested video does are found?First we have to go through the records to find out the shelf where it is kept and then we have to go there and find it. The current employees are used to find the requested videos. But the new employees go through a difficult time to find the videos.

02How do you handle the customers?Customers who give us a list or preferred video names, we help them to find out the videos. Customers who does not have a list have to go through the shelfs and find out what videos they want to watch.

03Whats the most wanted process that needs to be implemented? Employees go through a very difficult time in the process of handling the returned videos. It is hard to calculate fines and check deposits. And also employees find it difficult to inform the customers about the delay.

04What new features do you except from a new system?Workers expects a system that can track available videos, calculate fines, calculate the amount, gather customer information, store the information of rented videos and user friendly interface.

05Suggestions?Employees asked to create a system with a attendance record storage. It will help them to go to management with clear information when requesting holidays.

Q #QuestionSummery of the Analyzed information

01Are you happy with the current system?The customers are not that happy with the current system. They required more efficient service from the employees.

02Are you satisfied by the service provided?Around 70% of the customers are happy with the employees and their working pattern. 30% of the customers required quick service from the employees.

03Is it easy to find the required the video you wanted?Most of the customers exclaimed that it easy to find the required video if the video is arranged in a alphabetical manner. Also they said that employees help them to find the videos they want.

04Why do you come to this shop?Most of the customers told that it is because this shop has all the newest videos and the rental is fair.

According to our fact gathering techniques we came to the conclusion that the customers and some workers are in need of a new system. This new system will help not only the customers but also the company to gain more profits. We listed the components that should be there in the system. The system should include:1. A way to check the DVDs that are not rented and are rented.2. A way keeps customer information and rent details of each of the customers.3. A way to calculate the rentals and the fines.4. Issue a detailed bill to the customer.5. A database which keeps the track of all DVD/CDs the shop will have.

5.4 Assumption

When we are creating the DFDs we had to make some assumptions to draw it. They are:1. When a customer rent the DVD or the CD he/she wants he will get a detailed bill which has the information of the customers as well as the information on the item he/she rented.2. When a customer is renting or buying a CD/DVD he/she will have to provide their personal registration number at the cashier.3. Customers first have to register in the system to rent the DVD/CD from the shop.4. A form with the required information will be given to the customer at the registration.

Critical Evaluation

In our subject SAD (System Analysis & Design) we had to pick a company and find their problems in the current system. Then we had to find solutions to those problems through a new system. By going through this whole process we gained knowledge about the subject. It made the process of understanding the subject easier.We selected a DVD/CD shop to do our system because the environment of the shop is quite familiar to us. Apart from that we selected this shop because we knew the current manager and some of the staff. And also the current system of the shop is manual and had lots of problems. After going through the requirement gathering process we found out that the project will be little bit complicated than we anticipated.We used Microsoft Access as a database management tool for our project. First we created some logical designs from hand and then we tried to create the physical design from Access. In access we found out some components are hard to make. For example we werent able to make the Return Item Form. We had some issues with the macro which is running in our system. We found it bit difficult in making the system function perfectly.Our logical design and the physical design do not match entirely. Its due to the factor we changed our design when we are developing the system in Access because we had to make it look more user friendly. But we made sure that the important factors in our logical design were implemented. And also we tried to meet all the user requirements in our system.We had a hard time managing time to do our project. The time given to complete our project was not enough. In the end we created a system that met the customers requirements. We were having difficulties in the end due to the factor of time. But apart from that we felt that we handled the project well. This project gave us lot of practical experience in the working field. And also this project helped us to understand our subject much better.

On our first meeting we discussed for what we are going to implement out system. Through discussion found that we will be more comfortable if we selected MAX SOFT CD/DVD GAME AND VIDEO CENTER. On the first meeting itself, all the members were present. Earlier we were given of 3 choices to conduct our project on: CD renting and selling management system Customer Management System Car Park Management System So we have decided to implement the system on MAX SOFT CD/DVD GAME AND VIDEO CENTER, CD renting and selling management system. We had a brief discussion as to what we are targeting towards the succession of this system. The next meeting will be held on December 1st 2009. ..Mrs.Nadeera Ahangama.Systems Analysis & Design LecturerWeekly Meeting 2

Contribution to the project

I identified the company background. I studied the various methodologies available I contributed in drawing the DFDs and the data dictionaries for the data flows and the processes of the DFD. I contributed in creating table and Screen Designs for the database I contributed towards the technical feasibility study I identified the problems. I Studied the scope of the current system I contributed to the requirement gathering I contributed to the screen designing and critical evaluation. I also helped in describing the user manual.

Identifying the problemsI identified the problems of the old system and, objectives and opportunities of implemented system. Identifying the scope of the systemAfter studying the proposed system and how it performs I documented the scope of the system.Drawing the DFDs and the data dictionaries I drew the DFDs of level 0 and the context diagram. I also did the data dictionaries for the external entities and the data stores and the processes of the DFD.Technical feasibility part

Through the discussions with company staff we gathered lot of information, from that I gathered information for technical feasibility. So there are some assumptions I made here to gain my skills.

Contribution to the project.Mainly to the,Feasibility Study

Technical Feasibility Schedule Feasibility Operational Feasibility PIECES Framework Economical feasibilityGave my contribution to these areas:- Company back ground Summary of fact finding Level 0 diagram Assumptions Test plans Summary Screen designs Critical evaluation

Feasibility study An analysis of the ability to complete a project successfully, considering about legal, economic, technological, scheduling and other factors. This is the main part of the project. Why Im saying it because, if we want to complete a project successfully we should consider some certain facts. Likewise FEASIBILITY STUDY is shown us how a project should build up. Technical feasibilityProcess of determining whether the organization has the technology resources to develop or purchase, install, and operate the systemFor the technical feasibility I gathered information when we gathered data in the problem identification stage. There are some assumptions that I made targeting of improving our skills rather than making it 100 percent accurate. Schedule FeasibilityA schedule is a list of events that must occur at a specific period of time. When projects are put on a schedule, there is a deadline or desired completion date set.When we do a project timing is a very important thing. Completing a project on due date is very important. As here we completed our project on time

Operational FeasibilityPIECES FrameworkAs I said earlier I made some convenient assumptions to build our project. Therefore I took PIECES framework to describe our proposed system and compare with current system.Economic FeasibilityThis is mainly contributed to identify the cost and the benefits of the system. Through this we can calculate all the expenses we did throughout the year and benefits, from that we can do the ROI calculation.

I mainly contributed to create the data base. This is what we are going to installed as the new system. From this they can do their day today work easily. The data they entered manually can easily do by logging to this new system. Before we create this we had a brief discussion with the manager and employee. So we created this according to their requirements. Creation of the queries, forms and reportsI have created some queries in the database. The queries are:Dormant queryGenre queryMember historyMember nameThese queries were created using access and modified with SQL to meet the requirements of the user.
