👉 Criterion engineering is a systematic approach used in the design and development of complex systems, particularly in fields like software engineering and product management, to identify, define, and prioritize the key performance criteria that are most critical for success. It involves a structured process of analyzing stakeholder needs, market demands, and technical constraints to establish measurable goals and success metrics. This method helps in aligning the development process with business objectives, ensuring that the final product or system meets the desired quality standards and user expectations. By focusing on these crucial criteria, engineers can make informed decisions, optimize resource allocation, and enhance the overall effectiveness and efficiency of the development lifecycle.
