I was introduced to Statistical Thinking in October, 1988 when I attended Heero Hacquebord's course on "Statistical Thinking for Leaders". I went into the course thinking that I already knew everything I needed to know about SPC. I came out of the course with a whole new perspective on statistics, looking upon SPC and other statistical applications more as a way of thinking about processes so we can learn how to improve them. I also found that I could never again be satisfied with looking at numbers without graphical analysis.
