Imagine driving down the interstate at full speed—when you can see only 2% of the road.
Nerve-wracking? Nightmare-inducing? Sure. But manufacturing companies of every size and in every industry hinge product quality, customer satisfaction, and ultimately profitability on only about 2% of the available quality data. No wonder quality managers are losing sleep.
When faced with most problems dealing with processes, products, or service, quality professionals typically implement two types of remedial actions which were handed down to us by experts like Dr. Joseph M. Juran, Dr. Frank Gryna, et al. “Control of nonconforming product” and “root cause analysis with corrective action” are two separate and essential processes.
Quality at the source (QATS) has been used well before lean manufacturing became so popular. Many people in the quality function have applied the principles especially at critical work areas to detect nonconforming items and prevent them from moving forward in the process.
