Software Requirement Specification (SRS) Template – Start Writing SRS For Your Project

Add a comment October 4th, 2007 SachinKRaj

What is SRS?
A SRS is basically an organization’s understanding (in writing) of a customer or potential client’s system requirements and dependencies at a particular point of time (usually) prior to any actual design or development work. It’s a two-way insurance policy that assures that both the client and the organization understand each other’s requirements from every perspective at a given point of time.

Benefits of a Good SRS

Establish the basis for agreement between the customers and the suppliers on what the software product is to do.

Reduce the development effort.

Provide a basis for estimating costs and schedules.

Provide a baseline for validation and verification.

Serve as a basis for enhancement.

What should the SRS address to?

Functionality: What is the software supposed to do?

External Interfaces: How does the software interact with people, the system’s hardware, other hardware, and other software?

Performance: What is the speed, availability, response time, recovery time of various software functions, etc.?

Attributes: What are the portability, correctness, maintainability, security, etc. considerations?

Design constraints imposed on an implementation. Are there any required standards in effect, implementation language, policies for database integrity, resource limits, operating environment(s) etc.?

What are the characteristics of a good SRS?
A SRS should be:

Correct

Unambiguous

Complete

Consistent

Ranked for importance and/or stability

Verifiable

Modifiable

Traceable

Difference between System Specification and Software Specification:
Very often we find that companies don’t understand the difference between System Specification and Software Specification. Important issues are not defined up front and Mechanical, Electronic and Software designers do not really know what their requirements are.

The following is a high level list of requirements that should be addressed in a System Specification:

Define the functions of the system

Define the Hardware/Software Functional Partitioning

Define the Performance Specification

Define the Hardware/Software Performance Partitioning

Define Safety Requirements

Define the User Interface (A good user’s manual is often an overlooked part of the System specification. Many of our customers haven’t even considered that this is the right time to write the user’s manual)

Provide Installation Drawings/Instructions

Provide Interface Control Drawings (ICD’s, External I/O)

I have a small question. Is there any difference between the following three terms:
1. Software Requirement Specification
2. System Requirement Specification
3. Business Requirement Specification
December 31st, 2009 at 14:54 | #2

SachinKRaj

Yes Omkar, there are differences between these terms. Let me describe you in brief:
- Business Requirement Specification (BRS) describes what are the required business achievements, goals. It expresses the broad outcomes, business processes in a standardized way the business requires rather than specific functions the system may perform. The BRS is used to capture current and future needs of an organization. Business Analysts use this to captures WHAT is required. Software Developers then take these requirements and determine HOW these needs are to be met with the help of SRS.
- Software Requirements Specification describes the behavior of the software to be developed. It often includes a set of use cases that describe the interactions between the users and the software.
- System Requirements Specification describes all data, functional and behavioral requirements of the software under production or development. In other words, it describes what the system process or product must do in order to fulfill the Business Requirements.
  
  System specifications captures the System’s characteristics, partitions and functions, environment, diagnostics, data and reports, security, control points, vulnerabilities, and safeguards.
I read few definitions and tried to show you the exact difference between these terms. I hope the above description helps you to understand all these three terms easily.

Thanks a lot. Can you provide me the templates for the same? I have another question regarding Use Cases:

Consider the following scenario:

Regional Manager can list the employees for all the branches in his region. A branch Manager can list the employees only for his branch. How can i model this scenario? Should I take 2 separate use cases or only one?

Thanks a lot for sharing this topic here
We Addon Solutions also following Business Requirement Specification (BRS), Software Requirements Specification, System Requirements Specification and more technical documents when we go to execute any project. Without these documents you can not make 100% success, scalable project Its good method to follow also SDLC methods

SachinKRaj

Thanks mayur for sharing your thoughts. Yes you are right, SDLC is the basic back bone of all these technical concepts and terms.

You can use the template provided in this article. It is a generic template, you may or may not need all the terms provided in the SRS, but it is a good practice if you follow it.
