System Requirements Specification (SRS) is one of the most important documents you need to create if you plan on developing a software product. This document is an outline of what you need and expect your product to do. A good SRS is a reference point for everyone involved in the project, from stakeholders to coders, designers, and testers. The more detailed SRS you create, the fewer misunderstandings and delays you will face at the development stage.


Can you skip creating an SRS?

Startups are often chasing impossible deadlines and don't have time to waste on preparation. That's why they think that it is possible to produce a quality software product without creating a system requirements specification. Before you follow in their steps, consider the benefits of a good SRS:

How do you create an SRS?

Completing a system requirements specification may seem like a huge and troublesome task, however, there are ways to make it easier on yourself. Look up standard templates available in abundance online. Choose the one that seems closer to your needs and modify it as you go.

The most important source of information on writing an SRS is an ISO/IEC/IEEE 29148. This standard was adopted in 2011 and superseded an older IEEE 830-1998. Here are some guidelines from the newer standard to help you start your SRS:

What does a good requirement look like?

To help you speed the process of writing an SRS along, we have compiled a list of characteristics every set of requirements should possess. After jotting down every requirement, use this checklist to make sure you get the most out of your SRS. So, your requirements should be:

  • <medium>Complete.<medium> The SRS you create should contain all the information developers might need to complete the project.
  • <medium>Explicit.<medium> Your needs should be easy to understand and phrased in a way that will not lead to misunderstandings.
  • <medium>Measurable. <medium>Every requirement should contain measurable conditions and constraints to be easily validated and verified.
  • <medium>Consistent. <medium>The same standard terminology should be applied throughout the SRS to avoid misunderstandings.
  • <medium>Free of implementation constraints. <medium> Requirements should explain what you need without placing unnecessary restrictions upon the developers and designers. Let the professionals do their work, and the finished result will be better than you could hope.
  • <medium>Consistent.<medium> All requirement should be in agreement with each other, free of conflicts.
  • <medium>Viable.<medium> Requirements should not require major technological breakthroughs and should fit within the basic system constraints including timeline, cost, and risk.

The more precise your requirements are, the better developers will understand your needs. Here is a subtle trick to make most of your SRS. Avoid these terms at all cost:
