Követelménykiértékelés

Követelménykiértékelés, often translated as requirements evaluation or assessment, is a crucial activity in software development and project management. It involves systematically examining, verifying, and validating the requirements of a system or project. The primary goal is to ensure that the gathered requirements are complete, consistent, unambiguous, feasible, and accurately reflect the needs and expectations of stakeholders.

This process typically takes place after requirements have been elicited and documented. It aims to identify and rectify any potential issues early in the development lifecycle, which can significantly reduce the cost and effort associated with fixing errors later on. Common evaluation techniques include reviews, inspections, walkthroughs, prototyping, and formal analysis methods.

During a requirements review, for example, a team of experts scrutinizes the requirements document for clarity, correctness, and completeness. They might ask questions, identify contradictions, or suggest improvements. Inspections are more formal and structured, often involving predefined checklists and roles. Walkthroughs involve the author of the requirements explaining them to a group of peers. Prototyping allows stakeholders to interact with a preliminary version of the system, providing feedback on whether the requirements are being met. Formal analysis uses mathematical or logical methods to verify the properties of the requirements.

Effective requirements evaluation helps to build confidence in the project's direction and ensures that the final product will meet its intended purpose and satisfy user needs. It is an iterative process, and feedback from the evaluation may lead to revisions of the requirements, followed by further evaluation.
