In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.[2]
Requirements analysis is critical to the success or failure of a systems or software project.[3] The requirements should be documented, actionable, measurable, testable,[4] traceable,[4] related to identified business needs or opportunities, and defined to a level of detail sufficient for system design.

It is widely acknowledged within the software industry that software engineering projects are critically vulnerable when these activities are performed poorly.
