What is the process of agreement on the accuracy and completeness of requirements called?

The process of agreement on the accuracy and completeness of requirements is known as requirements validation. This process involves verifying that the documented requirements reflect the needs and expectations of stakeholders and confirming that they are indeed correct and complete.

During requirements validation, stakeholders, including clients, users, and project team members, review the requirements to ensure they align with the project's goals and objectives. The aim is to ensure that any potential misunderstandings or discrepancies are identified and addressed prior to moving forward into design and implementation phases. This reduces the risk of costly changes later on in the project lifecycle, enhancing overall project success.

In contrast, the other processes mentioned serve different purposes. Requirements analysis focuses on examining the requirements to understand their implications and feasibility. Requirements management involves tracking and controlling changes to the requirements throughout the project. Requirements elicitation is the process of gathering the requirements from stakeholders and is typically done at the beginning of a project to understand what should be delivered. Each of these has its place in the overall lifecycle of requirements, but only requirements validation directly deals with confirming their accuracy and completeness.
