The term that refers to a set of metrics used to assess the performance of a solution or requirement is Key Performance Indicators (KPI). KPIs are specific, measurable values that demonstrate how effectively an organization is achieving key business objectives. By focusing on quantifiable metrics, KPIs allow stakeholders to evaluate the success of a particular solution or requirement against predefined performance targets. They provide a clear way to measure progress, identify areas needing improvement, and make informed decisions based on data.

In the context of requirements analysis and design definition, KPIs are essential because they help ensure that the final solution aligns with business goals and delivers the intended value. They also facilitate communication among stakeholders by establishing a common understanding of success criteria and performance expectations.
