Best Practices for Developing and Writing Requirements

• All requirements must be testable and can fail when testing in a predictable way to prove implementation is correct. o Make sure each requirement is complete. A requirement can reference other requirements if there are dependencies.
  • Avoid duplicate requirements
  • Avoid contradictory requirements
  • It is preferred to write the requirement statement in positive terms. It is easier to prove a system can do something or has a characteristic than to prove it can’t or doesn’t.
  • Use your cross-functional team to review requirements for testability. They will help you identify conflicting requirements within your documentation.
• Requirements should be quantifiable and repeatable. Try to avoid qualitative requirements that add subjective decision making during implementation and verification.

Summary

The PRD serves as a contract between the Marketing and Engineering groups to ensure the company is creating and delivering the right product to their customers. Ensuring that all the requirements are identified can take time to analyze and develop; however, this effort is well spent providing clear design specifications to the engineers on what to develop and to the V&V engineers on what to test.
