I have spent numerous years working in and with all aspects of quality. During my earliest time in industry solving problems was more of a singular focus, but over the years the focus has become more of a team effort.
It’s safe to say that all quality practitioners are familiar with the control charting terms “common cause” and “special cause” variation. However, how many have really thought about their interpretations and associated action plans which could also add to variation?
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.
It shouldn’t come as a surprise, but even after all these years the ISO9001 quality management system (QMS) requirements still come under attack and mostly from those in the quality profession. I recently read another super critical appraisal of ISO9001 from someone who commented they were on the “front lines.” I’m not sure what front lines they’ve been on, but it’s obviously not the same ones I’ve been on.
Do you feel confused with all the polls, etc., being thrown about these days? Don't feel bad, as not many really understand polls, but we can usually say the same for surveys or consensus. Heck, even marketing experts get them wrong a lot of times.
