ACKNOWLEDGEMENT

4


In the beginning we would like to thank our GOD, the most merciful and beneficent, for

giving us the strength to complete this project with full determination.

My special thanks to my course instructor, Mrs. Ambreen Ahmed, without her help and

guidance we would not have been able to complete the report up to the mark and as well

if it was not for her support in the field of Microsoft acsses i don’t think we would be

able to present the screen shots in a appropriate way.

INTRODUCTION

5


This case study is about a video shop whose name us Sun Video Corporation. It has

expertise in video rental business. Their plan is to have a series of stores scattered

strategically around a metropolitan area. As being expertise in the video rental business

they offer great deal for their customer and provide a competitive edge for their

competitors. In this case we are required to do the work of the system analyst and go

through each process which the system analyst performs.

SCOPE

As all of you know that as the world is advancing the need for new system have increased

in every organization old systems are being replaced by new system, the reason behind

this is that the organization demands excellent quality work more profit to be earned in

short term and to gain more market share as quick as they can and to kick their

competitors out of the market. New system is:

User Friendly

More Efficient

They provide you with the latest security (I.E Fire Wall)

U can use internet proving you with the better speed and quality so you could

send and receive important e-mails

As mentioned above that what the new system does, our prime target is to create a

new and reliable system for Sun Video Corporation as it is offering many facilities to

its customers and it is proving a competitive edge.

OBJECTIVE

6


My objective is to make useful and user friendly system, so that non technical person can

also under stand it. It is easy for the company to use the system, providing the system that

would be designed for the company will consists of high security software (zone alarm

version 9) so that no hacker can break inside the system and stole data and installing

latest version of antivirus (I.E McAfee version 8.0) so the system is virus free and the

data is secured

PRELIMINARY INVESTIGATION

After receiving the request from Sun Video Corporation regarding their system our team

started its work with the very basic step that was searching for the problem by the method

of fact and finding techniques and gather the information regarding the problem that

was faced by the Sun Video Corporation.

FACT FINDING TECHNIQUES

This stage involves Interviews, conclusion, Survey, conclusion problem of the current

system, proposed solution to the problem of the current solution conclusion

Interviews

This was the basic step taken by our team this main reason for conducting interview was

that we would know that what are the problem that the company is currently facing and

how is it affecting their business? Although taking interview is not an easy task but we

manage to do it some how.

Conclusion

As a part of our first step we conducted this session and went to various people like the

managing director the company, the sales manager, the cashier and asked them about the

problem that they were facing, so that the information that they provide us would be later

used on.

Surveys

7


The second step that our group took was going on to surveys of different famous and

large video stores in order to see what is the main reason behind their success in the

market and what type of system are they currently using ad what are the benefits that they

are getting out of it?

Conclusion of Survey

Conducting survey was successes as it gave answer to most of are questions. Are prime

target was achieve we gathered all the relevant information and the irrelevant information

was discarded.

Problems with the current system

1. The problem that was detected and was commonly seen in the answer of

interviews was that all the work was done manually,

2. There were a lot of records being generated on papers, which was very

insecure if any thing happened to the store all the records would be destroyed

and that would provide the company in a great loss,

3. No proper security arrangements every one was accessible to the personal

records of every individual customer.

4. No privacy.

SOLUTION to the problems

After conducting the interviews and surveys it was observed that the company needed a

latest system, in order to improve its quality so there fore we came up with the new

system know as Video Rental System which was to use further to solve all the problems

of the users and the corporation.

Advantages of the system to be introduced

8


By introducing this system the company would be in safe hands due to the latest software

installed in the system which would prevent it from data hacking.

1. All the personal records would have right of privacy, as passwords can be easily

generated with the help of password manager guide which is an 8 user guide, user

friendly software which tells the user how to create a password and to use it.

2. It more reliable, Fast and user friendly.

3. It can generate automatic backup of each customer records. Incase the original

one is deleted the system can provide the user with the back up.

4. It would be sending automatic notifications to the user who have rented videos for

$50.

5. It will contain software which will the user on which shelf on what location is the

particular video which the customer s looking for this will provide them with time

flexibility and the customer would also be satisfied with this service.

6. Introducing this software would facilitate new customer enrolling and renting

movies from Sunny Videos that will make them enjoy high profit.

CONCULSION

9


After performing the necessary steps it was founded that sunny videos manual way of

working was more time consuming and it was not efficient to work with this system

as no privacy right were available. Being the system analyst it was decided that it is

necessary to introduce a new system for Sunny Video which is know as Sunny rental

Video

FEASIBILITY

Feasibility report means to identify the problem and summarizing the complete

objectives. It also creates broad data for the management team that would decide by

looking at the objects whether to move on the new phase or not. There are 4 types of

feasibility report which are mentioned below:

1. Technical

2. Operational

3. Economical

4. Schedule

Technological or Technical feasibility

10


Under this process the (IT) company determines weather the company has technological

resources to compose or purchase the system. Thus we figured the technical feasibility

report; we came to know the system which is proposed to the Sun Cooperation can be

operated easily. The system replace the manually work and transform all the manually

data in to computerize form .which would augment productivity. Training sessions are

required for the employees to educate them to excel to the newly proposed system and to

further understand and use the built in software that are inside the system to prevent their

company from suffering great losses.

Operational feasibility

Operational feasibility helps to crack business problems and provide opportunities to

business .Our system would help users to use the system effortlessly, thus eliminating the

paper work. Through data entry the system would cradle all the records of the customers

and hence the transactions made by sun video can be seen through any interface of sun

video. Through this all the customers record would be maintain properly without fuss. It

would show all the records of payment received, due dates, and pending payments. This

system would be user- friendly which would enable employees to learn and operate the

system fester achieving productive results.

Pieces framework

Pieces stands for Performance, Information, Economy, Control, Efficiency, Services

Pieces has merely 6 points.

Performance

The currant system is not that fast and efficient which waste sundry time in paper work

even after that the transactions of the customers are not recorded properly thus arising

conflicts between management and employees and customers .Thus performance is

effected, through new system the whole thing would be computerized and the task would

be done rapidly hence augmenting performance levels.

Information

11


The system will have its own data base through it the company can look and see all the

transactions of the customers thus having information about all it customers .

Economy

The system would be computerized, user friendly thus it would enhance productivity,

thus making the project economically strong. Perishing manually work thus codifying

and organizing the data of the customers properly. It would reduce the more workers,

thus cutting down the expanses and saving more money.

Control

Top management would have charge to control the system, thus it would decrease

pilfering , providing security . Thus every employee would have limited excess.

Efficiency

The system would be computerizes all over thus it would coup with all sinecures like data

entry, customer information, billing information resulting efficiency among employees

eventually satisfying customers .

Services

Our company would provide augment product or system thus in future if the sun

cooperation needs to have new tools we would provide them. Thus upgrading the system.

Schedule Feasibility.

Is that feasibility under which our company will meet its deadlines, and task to gratify

them? Under it we have set targets to finish what activity on which time.

Task completing dates

12


Feasibility report would be done in 3 days including technical, economical,

operational, schedule.

Pieces framework would be done in 4 days which would include performance,

information, economy, control, efficiency and services.

Investigation of (PI) will be done in 2days

Requirements of users will be done in 2.5 days

Analysis of system needs would be done in 4days

Development and documenting the software would take 8days

Cost benefit analysis would be done in 2days

Payback analysis would be done in 1 day

All the diagrams e.g. pert chart, data flow, level zero diagrams would be done in

5days

Level 1 diagram would be done in 3days

Data store would be made in 1 day

All Entities software would be done in 4 days

Making of screenshots in 2 days

Economical Feasibility

13


Under this feasibility we analysis weather benefits in making the new system are

more then the development cost. Is it profitable to take the task and make it? Will it

going to provide any benefits to the organization.

COST-BENEFIT ANALYSIS

Economic feasibility is performed by doing the cost-benefit analysis, which is the

process of identifying the financial benefits and costs associated with the

development of the project.

The evaluation of our project is being done on the following strategies

PAYBACK ANALYSIS

14


It is the process in which the organization identifies the time period in which the

system would pay back for itself.

The costs in the development of this project and the profits attained are shown below:

EXPLAINATION OF PAYBACK ANALYSIS

This graph was made on Microsoft Excel which helped in analyzing By the looking at the

above payback analysis graph it could be easily concluded that the system would payback

for itself in the 6th year after its development.

RETURN ON INVESTMENT(ROI) ANALYSIS

16


ROI= (Total benefits – Total costs) / Total costs

ROI= (436,500 - 269,500) / 269,500

ROI= 167,000 / 269,500

ROI= 0.61

EXPLAINATION OF ROI

According to the workings of the ROI the organization is getting 61% return on its

investment.

CONCLUSION

After performing different steps of feasibility it was concluded that our software is

feasible and easy to use for the company. Now we decided to move on to the design

phase.

DATA FLOW DIAGRAMS

Data flow is known as a geographical figure of the data. DFD denotes the process which

takes place in a system .it even shows how data evolve around through an information

system.

CONTEXT DIAGRAM

EXPLANATION OF CONTEXT DIAGRAM

18


The diagram says that the customers would interact with the system and it would show

his/her id, it would include whose payments are outstanding, whose payment are done,

whose videos are due. The new customer has to fill the form to avail membership for the

sun video. System would generate reports and management would be accountable to see

the report of the whole report... The accounts department would send cash which would

received by customers.

EXPLANATION OF LEVEL 0 DATA FLOW DIAGRAM

19


This diagram was made by using viso .In this case the when the customer will give there

id, the system would show customer payments, dues, etc. Accounts deportment sends

cash. Customer record shows rental information to compose a report. Which would give

to the management of the sun video. This system have information when the video is

rented then its receipt is made and passed to the customers. Payment which are which are

received from the accounts department is updated in customers records. If the customers

comes to the bonus level those customers’ details are forwarded to the accounts

department which generates motley or yearly schemes or bonus letters for those desire

customers.

LEVEL 0 DATA FLOW DIAGRAM

20


LEVEL 1 DATA FLOW DIAGRAM

21


EXPLANATION OF LEVEL 1 DATA FLOW DIAGRAM

In level 1 Data Flow Diagram, Customer Rental Record which is a data store sends

customer’s yearly details to the Create Yearly Bonus Letter. It advances to Free Coupons

Process which generates free coupons for the customer and both the items bonus letter

and free coupon goes to Create Customer Certificate. These three items that are coupons,

letter and certificate are sent directly to the customer.

DATA DICTONARY

22


Date dictionary is just like a dictionary which contains meanings of words,

Data dictionary is made by the analysis to keep track and record of the

information and thus it could be use further in future if required changes

in the system. Data dictionary contains the meanings of words which are used

in the system and data flow diagrams. It helps to

• Deplete redundancy

• Compose data flow in a constructive manner

• Provide aid on data stored files and save it

• Create deductive data flow processes

the data dictionary for this project is given below
