The very essence of the software requirements specification

Software Requirements Specification (SRS) very often forms a structured document form that captures all requirements of the clients’ future software. It’s common for software houses to make that document long, comprehensive and overwhelming. How not to get lost in all those technical terms and descriptions? What should every client know before the start of design creation and basic development phase?

It helps clients to assess the completeness of provided information and track any project enhancements.

What topics should the Software Requirements Specification cover?

Please notice that both – solid document and workshop summation – are good SRS examples. Before every project launch, software house team should ask clients those questions:

  • How would you describe the scope of work in detail?
  • Are you able to pinpoint the most important features for your project? It could be helpful for software designers. (i.e. navigation aids, website architecture, lead magnets)
  • Could you tell us something more about your new website/web or mobile application use cases (primary and secondary)?
  • Have you ever thought about further enhancements which could be necessary for your project in the future?

Those questions are only exemplary. There is no one and only software requirements specification template. Software requirements differ from the project. But in fact, and as a matter of principle, software requirement specification should cover:

Overall Description

  • this section contains the general view of the project and the environment where it will be used, describes the expected user audience and constraints, assumptions and dependencies which can be identified. The most important are: product perspective, product functions, user classes and characteristics, operating environment, design and implementation constraints, assumptions and dependencies.

Requirements (functional and nonfunctional) 

  • such as: user interfaces, software interfaces, communications interfaces, performance and safety requirements. Information from this section should elaborate how the system is going to interact with external components.

Use case scenarios

  • are the most important things when it comes to software creation. There is no better way to explain the idea hidden behind the project. Every client should know how his software should work and how he would like to make money on it. It is essential to provide such information as: business triggers (events that may cause the first interaction with the software), basic flow (the ideal user journey when everything goes right) and alternate flows.
