When the gathered requirements are complete, accurate, reliable, feasible and testable, the requirements can be termed as a good or perfect requirement. As a Business Analyst, there are quite a few methods or guidelines to validate a requirement to ensure that the requirement is good or perfect. Few of these methods are mentioned below –
