([Wikipedia](https://en.wikipedia.org/wiki/Requirements_engineering)) <!-- REAL-GENERATIVE-MEDIA:END --> > Summary stub · part of Systems Engineering · [Wikipedia source](https://en.wikipedia.org/wiki/Requirements_engineering) ## Summary Requirements engineering is the process of defining, documenting, and maintaining the requirements that a [[System|system]], product, or software must satisfy. It spans elicitation from stakeholders, analysis and negotiation of competing needs, specification in clear and verifiable form, validation, and ongoing change management. Good requirements are unambiguous, traceable, testable, and prioritized, providing the baseline against which design and verification are judged. The activity is a recognized cornerstone of both software and systems engineering. ## Key points - Elicits, analyzes, specifies, validates, and manages requirements - Aims for unambiguous, traceable, and testable statements of need - Negotiates competing stakeholder priorities and constraints - Provides the baseline for design and for verification and validation - A shared cornerstone of software and systems engineering ## Relation to Systems Engineering Requirements engineering is a foundational systems-[[Engineering|engineering]] activity, since requirements define the problem the whole system must solve and anchor verification throughout the lifecycle. ## Sources - [Requirements engineering — Wikipedia](https://en.wikipedia.org/wiki/Requirements_engineering) Back to Systems Engineering --- <!-- SEMIOTIC-PROFILE:START --> ## Semiotic profile > *The semiotic universals this article invokes, machine-derived from the crossref — **unverified** (born so).
