Use PDSA to design a small, measurable test for a plant-floor process change.
Small tests protect the plant from expensive certainty. The teach PDSA stands for Plan, Do, Study, Act. The power is not the letters; it is the discipline of learning before scaling. Plan states the problem, the theory, the predicted result, the measure, and the safe test boundary. Do runs the change small enough that failure teaches without damaging the plant. Study compares actual results with the prediction, including side effects such as cycle time, queue length, or operator confusion. Act decides whether to adopt, adapt, abandon, or test again. The mechanism is controlled learning under real conditions. In plant management,…
