Hello, all:
I think I'm finally getting a little momentum on this book project. Here's Chapter 4, Identifying Causes. As always, I greatly value any feedback and criticism you might have.
Talk to you soon,

Ajit and Charlie--
1) Cause and Effect Diagrams (aka Fishbone Diagrams) are not mentioned at all. I have never found a great deal of value in these, so I just skipped over any mention of them. They're very popular tools, though, and my guess is that some people might be disappointed that they're not addressed.
2) There's no mention of common cause variation versus special cause variation. I would have launched into a explanation of the central limit theorum and control charts, and it seemed to un-focus the chapter. So I left it out.
3) The use of data is described and encouraged, but it isn't the overriding focus of the chapter. For a chapter on problem causes, this could bug some people.
