Question

Quizplus · Accepted Answer

Design specification limits are the bounds within which a product or process must perform to meet customer needs. These limits should be wider than the control limits, which are used to monitor and control a process over time. By having wider design specification limits, there is more flexibility in the process and a greater chance of meeting customer needs. However, control limits are narrower and focused on minimizing variability within a process for consistent performance.
