Which KPI represents the speed of improving system capacity after SOP changes?

• A. Compliance rate
• B. Time-to-capacity improvements
• C. Deviation rate
• D. Training completion rate

Answer: (B)

The main idea is tracking how quickly capacity increases after changes to the SOP. Time-to-capacity improvements measures the duration from deploying the SOP changes to reaching a defined capacity target, so it directly reflects the speed of improvement. This makes it the most appropriate KPI for gauging how fast the system adapts and expands its capacity after changes.

Other options don’t capture speed. Compliance rate tells you what fraction of processes followed the SOP, not how fast capacity grows. Deviation rate looks at how much practice diverges from the SOP, again not about velocity of capacity gains. Training completion rate indicates whether people finished training, not how quickly the system’s capacity improves after those changes.
