"KPI" stands for Key Performance Indicator in business performance measurement. KPIs are measurable values that demonstrate how effectively an organization is achieving its key business objectives. They provide insight into performance trends and help in decision-making processes. Organizations use KPIs to set targets, monitor progress, and align their activities with strategic goals. Effective KPIs are specific, measurable, attainable, relevant, and time-bound, enabling businesses to track success and identify areas for improvement.
