All organizations are involved in process improvement today. The body of knowledge is expansive. One requires an understanding of Lean, Six Sigma, Theory of Constraints, Data Science, Systems Thinking and Process Modelling to be thorough. Sometimes, it's wise to bring in a seasoned coach to support your projects.
A coach is someone who shows you how to improve your game.
I've been fortunate to work with a few food manufacturers working to resolve long-standing Quality problems. My background in applied statistics meant that I was able to contribute a lot to understanding process behaviour through existing data. In one case, we resolved a very costly problem using clue generating methods that identified the root of the problem. These are uncommon, but powerful methods in problem solving.
Manufacturers typically take lots of measurements and have large amounts of data. This data often contains insights into process behaviour.
Medical device manufacturers are subject to the most stringent Quality requirements and Good Manufacturing Practices. I've worked with some very smart people in this industry on designing complex experiments and we've discovered insights that were not known beforehand.
My career evolved through Quality Management and I have lead the implementation of several Quality Management Systems including ISO 9001, ISO 17025 and ISO 13485. If you are implementing a QMS, I can help.
