Business and Integration Requirements Document (BIRD)
This document specifies the functional (e.g., activities performed and outputs produced) as well as nonfunctional (e.g., performance and security) features of the system to be developed or acquired. The requirements document is a key resource for systems development, user involvement and project management.
The requirements document is created early in the system life cycle and is subject to formal/informal reviews by the clients, systems developers, project managers and testers throughout the life cycle. It forms the basis for ongoing development and testing of the system to meet the requirements of the client. It thus supplies sufficient information to the client to establish a solid foundation for subsequent assessment and approval. It also provides the development/acquisition team with a basis for on-going management and testing.
