7 a) May state what (reactions, behaviours, or services) the system should not do. b) services the system should provide, c) how the system should react to particular inputs, and d) how the system should behave in particular situations. Functional Requirement
9 § Independent – loosely coupled with one another § Negotiable – Stories are what and why , not how ( 99% ). § Valuable – for the customer! § Estimatable – Effort/Cost of design, build, and test. § Small (sized appropriately) § Testable – pass or fail INVEST in good requirements
10 § Can someone do this and integrate it later into the main project? § Do we all understand what this is? § Is this important for the customer? § Can we estimate the cost of this (complexity, LOC, effort, or time)? § Is this appropriate for a Sprint (period of time)? § Do we know how to test it and prove it is complete? INVEST in good requirements
