Here's what Prof. Henry Mintzberg writes in his paper "Developing Theory about the Development of Theory:"
“My work is loaded with diagrams, seeking to express every which way how the ideas I am trying to make come together. Aristotle said ‘The soul...never thinks without a picture.’ I try to help my soul think. [...]
These diagrams really help me a great deal: I can see it all at a glance, even if outside my head. But not always into other heads. I have been puzzled to find that some people are puzzled by these diagrams. They don’t think in such terms, nor are they even able to see it in the work of others. Even many of my own doctoral students, sometimes including the best, when urged by me to express their ideas in diagrammatic form, have not gotten past a 2x2 matrix or two. Maybe this has to do with my education as a mechanical engineer — probably the only thing left of that — or at least my predisposition to do that kind of education, because I like to see things altogether, at a single glance, to quote a famous composer.”
My book "Spointra and the Secret of Business Success," as well as the related initiative BizBigPic, is quite heavy on the graphic side. However, this blog and BizBigPic, which uses a blog technological platform, are perfectly suited for discussions. So, if you have any questions, please don't hesitate to start a discussion.
