A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirement Document &quot;PRD&quot;.<br /> <br /> Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system level, on the module level and on the level of technical details.<br /> <br /> == See also ==<br /> <br /> * [[Benchmarking]]<br /> * [[Bit specification (disambiguation)]]<br /> * [[Design specification]]<br /> * [[Diagnostic design specification]]<br /> * [[Product design specification]]<br /> * [[Software Requirements Specification]]<br /> * [[Software development process]]<br /> * [[Specification (technical standard)]]<br /> * [[Verification and Validation (software)]]<br /> <br /> == External links ==<br /> <br /> * [https://en.wikipedia.org/wiki/Functional_specification Functional specification] @ Wikipedia.org <br /> <br /> [[Category:Software engineering]]</div>
