Knowra Requirements engineering Requirements engineering Requirements engineering is the systematic process of eliciting, analyzing, specifying, validating, and managing a system’s needs and constraints throughout its development.
Requirements elicitation : The process of discovering stakeholders’ needs, expectations, and constraints for a system. It begins the process by gathering the raw needs that requirements engineering must clarify.
Stakeholder : A person, group, or organization that can affect, be affected by, or has an interest in a system. Stakeholders supply needs, impose constraints, and judge whether requirements serve their interests.
Agile software development : An iterative approach to software development that emphasizes frequent delivery, feedback, and adaptation. Its evolving backlogs and short feedback cycles contrast with treating requirements as a fixed, early specification.
Systems engineering : An interdisciplinary approach to designing, integrating, and managing complex systems across their life cycles. Requirements engineering is one activity within this broader discipline.
Requirements analysis : The examination of proposed requirements for feasibility, consistency, completeness, and priority. It resolves conflicts and tests whether elicited needs can form a coherent specification.
System requirement : A documented condition or capability that a system must satisfy to meet a need or obligation. It is the central unit that requirements engineering discovers, specifies, and manages.
Product backlog : An ordered, evolving list of work items for a product, maintained by the product owner. In Scrum, it provides a practical, continuously revised home for product requirements.
Business analysis : The practice of identifying business needs and recommending solutions that deliver value to stakeholders. It overlaps in discovering needs but also evaluates organizational change and solution options.
Requirements specification : The documented description of a system’s required functions, qualities, interfaces, and constraints. It records the agreed requirements in a form developers and stakeholders can inspect.
Functional requirement : A requirement that states a behavior or service a system must provide. It expresses what the system is expected to do.
