What is the purpose of a System’s Requirements Document?

The purpose of a System’s Requirements Document is to specify the requirements for development and performance. This document serves as a comprehensive guide for what the system must achieve in terms of functionality, performance, and constraints. It establishes clear expectations and criteria against which the system can be designed, developed, and tested. By detailing both the functional requirements (what the system should do) and non-functional requirements (how the system should perform), the document ensures that all stakeholders have a mutual understanding of the system's capabilities and limitations. This clarity is crucial for successful project execution, as it helps prevent scope creep and misunderstandings during development. The System’s Requirements Document acts as a foundational reference throughout the systems acquisition process, directly influencing design decisions and ultimately contributing to the successful completion of the project.
