Organizations decide how teams will analyze, document, validate, and govern changes to requirements, working within Agile, V-model, or other processes.
The ultimate aim is to deliver a product or service that satisfies the requirements agreed to so that requirements engineering naturally flows into the design and manufacture or implementation.
Sound requirements management is a foundational discipline for product, systems, and software engineering teams. Organizations with mature requirements management practices:
Build products that better meet market needs, achieving competitive advantage
Reduce rework from missed or poor-quality requirements, shortening product cycles
Create a more accurate, shared product vision more quickly, speeding product delivery
Enhance reuse, reducing development costs
Requirements management is dedicated to eliciting, analyzing, and documenting business, user, and market needs. Project management is a more generalized discipline that can be applied to a broad range of deliverables, not limited to requirements.
Common requirements management challenges include:
Common requirements categories include:
User stories are a requirements elicitation technique used by Agile teams that captures needs and wants from the user's point of view, typically using first-person “I need, I see” narration. User stories are an excellent way to build an understanding of the user's world and empathize with their challenges. Epics organize multiple user stories under a common theme.
