Which KPI is used to measure whether orders are served within the promised time?

• A. Order accuracy
• B. Yield/waste
• C. On-time service
• D. Food cost percentage

Answer: (C)

On-time service focuses on delivering orders by the promised time. This KPI measures the percentage of orders that are served within the expected window, letting the kitchen gauge speed, pacing, and reliability in fulfilling commitments to customers. It directly reflects whether service timing is meeting expectations, which is critical for satisfaction and turnover. Other metrics like order accuracy check if the correct items are sent, yield/waste looks at how efficiently food is prepared with minimal waste, and food cost percentage tracks cost control, not timing. So, the best choice for assessing whether orders are served within the promised time is on-time service.
