Purpose: The primary purpose of the Requirements Definition document is to develop a basis of mutual understanding between the business users and the project team about the requirements for the project. The result of this understanding is an approved Requirements Specification that becomes the initial baseline for product design. Also referred to as a Requirements Definition, this document becomes a reference for determining whether the completed product performs as intended. All system requirements, (e.g., software, hardware, performance, functional, infrastructure, etc.) should be included.
This stage involves analysis of the business processes and needs, as well as translation of those processes and needs into formal requirements. This subsequently allows for the planning of the testing activities that validate the performance of the product.
