A Performance Requirement is a specific criterion that outlines the expected level of performance for a product, service, or system. It serves as a benchmark to evaluate whether the item meets the necessary standards for functionality, efficiency, and quality. These requirements are crucial in various fields, including engineering, software development, and manufacturing, ensuring that the end result fulfills user needs and regulatory standards. In the context of project management, performance requirements help teams set clear goals and expectations. They guide the design and development process, allowing stakeholders to assess progress and make informed decisions. By establishing measurable outcomes, performance requirements facilitate accountability and continuous improvement throughout the project lifecycle.
