Metrics are vital to assess whether a process improvement initiative is delivering its intended benefits. The right metrics depend on the goals of the initiative—cost reduction, speed, quality, etc.
Cycle Time:
Time taken to complete a task or process from start to finish.
Shorter cycle times indicate increased efficiency.
Error Rate or Defect Rate:
Number of errors per unit of output.
A key measure of quality.
Throughput:
Volume of output produced within a given time frame.
Cost per Transaction:
Measures cost efficiency in repetitive processes.
Customer Satisfaction (CSAT/NPS):
Captures the impact of internal changes on external experiences.
Employee Productivity:
Tracks output per employee before and after changes.
First Pass Yield (FPY):
Measures the percentage of work completed without rework.
Using a combination of leading and lagging indicators provides a comprehensive view of improvement outcomes.
