Dear Students!
In this post you will learn How to make SRS document? for your final project CS619. As we know that the students of BSCS/BSSE/BSIT in 7th/8th Semester and MIT/MSCS in 3rd/4th Semester have to select CS619 Project. This project is a must to get Degree. It carries 6 credit hours. So, here we will guide you about the first step of CS619 Project i.e. Gathering and Analysis Requirements.
PHASE-1 Gathering and Analysis Requirements
In this phase you are required to make SRS Document.
What is SRS?
SRS stands for Software Requirements Specification. It is a detailed
document that tells about how the system is expected to perform. In this
document, following topics are covered:
- Scope of the Project
- Software Requirements
- Functional requirements
- Non-Functional requirements
- Use Case Diagram
- Usage Scenarios
- Adopted Methodology
- Work Plan
Scope of the Project
What is scope?
The scope of the project defines the necessary information required
to start a project. It basically answers to the following questions:
- What are the needs?
- What is your goal?
- How the system will fulfill the user needs?
- Why user should use this system?
For example:
Here is an example of scope of the project:
An online departmental store.

Cash and Carry online Departmental Store
"Cash & Carry is an Online Departmental Store where people will be offered with a wide range of both grocery and non-grocery items to buy online. It offers items to residents located anywhere in Pakistan. This store is being developed to help users to explore their daily, weekly or monthly required items. The payment gateway methods are easypaisa or cash on Delivery.
In this project, our goal is to facilitate the users to buy grocery and non-grocery items at the ease of their home. The users will interact with our store through Website. Cash & Carry Online Store System is built in the form of Web Application which includes User registration/login system, search system, information flow charts, administration module, payment gateways etc. When the user makes a transaction and purchases an item from this store, he/she will receive items at his/her doorstep along with an invoice.
Moreover, this system acts as power up approach for people. And also, time saving. As some people like working women/men and old age persons might not be able to go out due to some reasons like tiredness, illness or time constraint. So, Cash & Carry Online Departmental Store plays a significant Role in the life of people whether it’s a man, a woman, a student, or an elderly."
💡 Tip: Don't need to add history and philosophy. Just write the
specific content only in your own words.
Software Requirements
Here you will write the functional and non-functional requirements in detail.
Functional Requirements:
For example:
This example is related to the above mentioned sample project.
The user interface will be simple enough to navigate easily. It will contain only two broad main categories Grocery and Non-grocery items on the home page with other tools like search, add to cart, login/signup buttons, FAQ and information flow charts links etc.
Registration
The customers can register themselves into our system and then login to place order. Registration is mandatory to buy and pay for the items.
💡 Tip: You should write all the required functionalities of your
project. There may be more than these like: Search, Order Track, Save
Selection etc.
Non-Functional Requirements:
For example:
This example is related to the above mentioned sample project.
Usability
The usability is a key factor to facilitate the user. The system must provide a user-friendly environment to its customers. To interact with the user, system should give a proper list of categories for the user to search their required items.
Security
To ensure that the user’s information is safe, the system should protect the user’s data. It must refrain the hackers to unauthorized access. The system must use specific standards to secure it from malware attacks and unauthorized access.

💡 Tip: You should write all the required non-functionalities of your
project. There may be more than these like: Accuracy, Reliability, Performance
etc.
Use Case Diagram
What is Use Case?
A Unified Modeling Language which represents the
interaction between the user
and the system. It shows the relationship that exists between the system and
the user. The user/actor is involved in different use cases like: login,
registration, search, add to cart etc.
For example:
Here is an example Use case diagram of the departmental store
Usage Scenarios
What are usage scenarios?
They describe the events/actions that occur when the user interacts with the
system. They show the real world example that how the people or users interact
with the system, What actions do they perform?, What are the conditions?, What
will be the exceptions if the action does not meet the desired conditions?
So here in this section you are required to write the usage scenarios of all
cases in the table format which explains:
- Use Case title
- Use Case Id
- Actions Description
- Alternative Path
- Pre-conditions
- Author
- Exceptions
- Post-conditions
You are supposed to provide usage scenario for each use case present in your
use case diagram. So basically it explains each use case in detail.
For example:
Here is a sample of Usage Scenario from the Online Departmental Store Project.
Use Case Title |
Register |
Use Case Id |
UC 1.1 |
Actions |
A registration Page will open |
Description: A user can register themselves
by providing his/her information like: Name, Username, Email, Phone Number,
Address, and Password. |
|
Alternative Path: The user must register to place an order and
add items to cart. |
|
Pre-conditions: The system should provide a
proper form for user to fill their required information. |
|
Author |
Exceptions |
Unregistered User |
If the user leaves
any field empty or inputs wrong email/phone number or the inserted password
does not match the requirements then user registration will not take place. |
Post Conditions: A success message should be
displayed on successful registration. |
🖉 Note: This is only one scenario from the use case diagram. You have to write scenarios for each use case present in the Use case Diagram.
Adopted Methodology
Here you will write in detail about which Software Development Lifecycle SDLC Model you adopted for this project. In short you will write about Waterfall Model and Spiral Model with diagrams. And then you will write VU Process Model which is a combination of Waterfall Model and Spiral Model proposed by Virtual University of Pakistan.
Waterfall Model
What is waterfall model?
Spiral Model
The spiral model is a SDLC risk-driven method. It combines the iterative models with elements of Waterfall model. The model works well for large projects. In this model each next stage is link to the previous so commutation flow can go in both directions and if changes come then they can easily be adjusted. This guarantees that there is no conflict with the previous requirements.
VU Process Model
VU process model is called hybrid approach of website development. It is the combination of both waterfall and spiral model. This model is easy to understand. It is proposed by Virtual University of Pakistan. This model will maximize the quality of the website and reduce the risk because waterfall avoid overlapping which makes it easy to understand and spiral uses for critical projects. We need both functionalities for our project so that’s why we use VU process model because it’s a combination of both spiral and waterfall process Models.
What is Spiral Model?
The spiral model is a SDLC risk-driven method. It combines the iterative models with elements of Waterfall model. The model works well for large projects. In this model each next stage is link to the previous so commutation flow can go in both directions and if changes come then they can easily be adjusted. This guarantees that there is no conflict with the previous requirements.

Work Plan
Here you will provide Gantt chart of your final project.
What is Gantt Chart?
It is a type of horizontal bar chart which tells the timeline of the project. It shows the starting and finishing time of your project phases. See below to get an idea.
For example:
We hope you understood these concept clearly. Feel free to ask any question.
