(2023-05-11) Chin Process Behaviour Charts More Than You Need To Know

Cedric Chin: Process Behaviour Charts: More Than You Need To Know. This week’s Commoncog post is for members only; next week’s post will be free. Process Behaviour Charts: More Than You Need To Know (members only) — We last talked about process behaviour charts in Part Two of the Becoming Data Driven in Business Series.

This week’s essay is a deep dive into the process behaviour chart.

At the end of this week’s essay, I write that I don’t really know why this technique isn’t more popular. Amazon itself does not use XmR charts (Weekly Business Review) — or at least not widely (though Bryar and Carr mentions them in Working Backwards). They get to an understanding of variation through other means.

there are some crazy real world case studies in Donald Wheeler’s Making Sense of Data that go far beyond manufacturing.

Why Don’t We Change? — Eric Nehrlich is an executive coach, and he told me last week that my ‘will’ problems in Judo are actually quite well known in coaching

Lessons Not Worth Learning — Will Larson, with something poignant and beautiful: My point is not that these lessons are wrong, they certainly are not wrong in many cases. That said, I think you should choose the beliefs that help you live a meaningful, ethical life.
