Prevention better than cure – get requirements right first time
Conclusion: Unless the attributes of user stories (agile) or high-level requirements (waterfall) are succinct and testable, business systems specifications will lack rigour and could compromise the system’s integrity. To ensure these attributes, i. e. succinct and testable, are present, the stories and high-level requirements should be peer reviewed to identify content that is unclear or just expressing an unrealistic ‘want/wish’ list.
It is important the stories or high-level requirements contain sufficient context to enable systems requirements, i. e. functional and non-functional, to be developed because unless they do it will be difficult to prioritise them based on business drivers.
Similarly, the results of user acceptance testing should be peer reviewed to ensure the agreed requirements have been met and the output is verifiable.
