Requirements Specification
Requirements specification is the step where requirements are documented and delivered to stakeholders. This process includes comprehensive documentation of requirements in sufficient detail to enable system design, development and test activities to proceed. In addition, the requirements specification should be easy to update. It is an essential piece for transparency and communication with both the team members and stakeholders. Requirements can then be traced back to this document throughout the project lifecycle.
