Requirements Documents are formal written documents that outline, in detail, the technical and logical requirements of a project. This document is written during Steps 1 and 2 of the SDLC. The intended audience of a requirements document includes anyone involved in the project who needs a deep technical understanding. This document is often used as the primary outline of a project for the technical team, as the source of task assignments, and as the working document for team members.
There are various requirements documents, each structured differently to serve the needs of different projects such as consumer products or services, marketing campaigns, and projects that fit a business’s specific needs. For the sake of focus, we will explore one type of requirements document here, the Software Requirements Specification (SRS), keeping in mind that this is one of many types that may be encountered.
