Which of these are examples of business metrics or Key Performance Indicators commonly referred to as KPI’s?

Key Performance Indicators (KPIs) and business metrics quantify process performance, efficiency, quality, and operational resource usage. Cycle Time measures throughput speed and efficiency, Defects measure process output quality and error rate, Number of Units Reworked measures waste and non-value-added activity rate, and Labor Hours measure resource effort and operational input. Because all listed items represent standard operational metrics and KPIs used in Lean Six Sigma to monitor and evaluate overall process health, option E is the correct answer.

A: Cycle Time is a key efficiency metric, but options B, C, and D are also valid business metrics/KPIs.

B: Defects measure process failure rate and quality performance, but options A, C, and D are also valid business metrics/KPIs.

C: Number of Units Reworked measures process waste, but options A, B, and D are also valid business metrics/KPIs.

D: Labor Hours measure resource input and cost, but options A, B, and C are also valid business metrics/KPIs.
