What percentage faster is the cycle time for 6QAs vs non-6QA accounts?

• A. 10%
• B. 20%
• C. 30%
• D. 40%

Answer: (C)

Measuring how much faster a process is compared to another comes down to the relative reduction in time. To find the percentage faster, use the formula: (old cycle time − new cycle time) ÷ old cycle time × 100%. If the 6QAs make the cycle time 70% of the non-6QA baseline, then the reduction is (1 − 0.70) × 100% = 30%. For example, with an original cycle time of 10 minutes, the 6QA cycle time would be 7 minutes, which is 3 minutes faster—that's 30% of the original 10 minutes. So 30% is the correct way to express the improvement. The other percentages would correspond to different amounts of time saved (e.g., 10% means a 10% reduction, 40% means a 60% of the original time, etc.).
