Sustain metrics often include:

• A. Project ROI only
• B. Color of desks
• C. Process adherence rate
• D. Shoe size of workers

Answer: (C)

Sustain metrics measure whether improvements stay in place by looking at ongoing performance and whether the new process is being followed. The best answer is process adherence rate because it directly shows if people are consistently following the defined standard work and improved workflow, which is essential to preserving the gains over time. When adherence stays high, the benefits—like reduced waste, stable quality, and shorter cycle times—are likely to persist. Other options don’t reflect ongoing process performance: ROI is a financial measure that doesn’t guarantee daily process health, and attributes like the color of desks or shoe sizes have no relation to how the process is executed.
