Bill Dettmer has recently published The Logical Thinking Process - A systems approach to complex problem solving which is a significant update to his earlier text, "Goldratt's Theory of Constraints: A Systems Approach to Continuous Improvement" (GTOC).
I've learned a lot from Bill's books over the last decade so I'm delighted that he has agreed to answer a few questions here on the tocthinkers.com blog. I'll post the first three questions shortly and more will follow. If you got any questions you'd like to ask Bill then please send them on to me and I'll post them to the blog if they seem appropriate.
