Requirement Specifications

The requirements specification is a document that clearly and precisely defines the customer’s logical requirements (or needs) in such a way that it is possible to test the finished system to verify that those needs have actually been met. The point is to ensure that the customer’s needs are correctly defined before time, money, and resources are wasted working on the wrong solution. Typically, writing a formal requirements specification is the final step in the analysis phase of the system development life cycle.
