Which of the following is a detailed description of the requirements for a system?

The requirements specification is a comprehensive document that outlines the detailed needs and expectations for a system. This document serves as a critical reference point for developers, project managers, and stakeholders throughout the project lifecycle. It includes functional requirements, which define what the system should do, as well as non-functional requirements, such as performance, usability, and security.

A well-constructed requirements specification ensures that all parties have a clear understanding of what is needed and helps to avoid misunderstandings or scope creep as the project progresses. It acts as a foundational document for subsequent phases of development, including design, implementation, testing, and validation. By clearly detailing the system requirements, it facilitates effective communication among team members and stakeholders, ultimately leading to a more successful project outcome.

In contrast, the project plan typically outlines the timeline, resources, and activities for a project but does not specifically detail system requirements. Technical documentation addresses aspects related to the technical implementation of the system but may not include comprehensive requirements. The project charter defines the project's objectives and stakeholders but lacks the detail necessary to describe system requirements thoroughly.
