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:
- Complete. The SRS you create should contain all the information developers might need to complete the project.
- Explicit. Your needs should be easy to understand and phrased in a way that will not lead to misunderstandings.
- Measurable. Every requirement should contain measurable conditions and constraints to be easily validated and verified.
- Consistent. The same standard terminology should be applied throughout the SRS to avoid misunderstandings.
- Free of implementation constraints. 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.
- Consistent. All requirement should be in agreement with each other, free of conflicts.
- Viable. 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:
Wrong: The system shall be the best among similar products.
Right: The system shall implement feature_1, feature_2, and feature_3.
Wrong: The software interface shall be user-friendly.
Right: The software shall be installed in less than 1 minute.
Wrong: The project shall be completed in a minimal possible amount of time.
Right: The project shall be completed within 2 months.
Wrong: The application design shall be better than that of the main competitors.
Right: The application design shall contain three main colors.
Wrong: The system shall employ material design, if possible.
Right: The system shall employ material design.
Now you know how to create a good system requirements specification for your project. Use these guidelines and standard samples to save time and resources while creating your SRS.
