What is the primary output of the requirements analysis phase?

The primary output of the requirements analysis phase is a requirements specification document. This document serves as a detailed description of the requirements identified during the analysis phase. It consolidates all the information regarding what stakeholders need from the system, product, or project, ensuring that all requirements are documented clearly and unambiguously. This specification is critical for guiding project teams in development and ensuring that the final deliverable meets the intended needs of the business and its stakeholders.

The requirements specification document encapsulates both functional and non-functional requirements, providing a comprehensive reference for designers, developers, and testers throughout the project lifecycle. By having a well-defined requirements specification, it enhances communication among stakeholders and minimizes the risk of misunderstandings, further ensuring the success of the project.

The other options, while important outputs within various project phases, do not specifically stem from the requirements analysis phase. A project charter generally focuses on establishing the project's objectives and scope rather than detailing requirements. A risk management plan is aimed at identifying and mitigating risks throughout the project, and a business benefits analysis evaluates the potential advantages of a project but does not define specific requirements.
