I am happy to report that I can now call myself a certified Lean Six Sigma Black Belt. While I consider this a worthwhile achievement, some friends and colleagues have questioned why I was spending time, effort and money on “just getting a piece of paper” that doesn’t mean much in the world of sales [...] A while back, SEO guru Glenn Crocker and I were talking about how visual analytics can help with search engine optimization. Getting useful SEO information usually requires crunching data for thousands of links, so it’s quite useful to have something that takes us from a quick overview to the interesting details. To illustrate how visual analytics [...] On April 19th, 2010, IATA, the chief trade group representing airlines, issued a press release which states in part: “IATA criticized Europe’s unique methodology of closing airspace based on theoretical modeling of the ash cloud. ‘This means that governments have not taken their responsibility to make clear decisions based on facts …’ said [Giovanni] Bisignani [...] Today’s shrinking resources may tempt us into rushing things along, yet we need to be careful when relying on graphics to make decisions.

In those situations we first need to determine what information the data contains and what it can and cannot tell us. We need to ask questions of the data and determine whether it makes sense, [...] In order to make profitable decisions, we need good information. Whether we base our decisions on sales, customer perceptions or the number of widgets we shipped last month, our information comes from some system that collects and measures relevant data for us. In my Six Sigma Black Belt class we recently discussed the challenges of developing [...] One can reasonably argue that processes don’t produce results, people do. In and of itself a process does nothing. It takes people to engage in a process – for better or for worse – to produce something. On the other hand are quality pioneers like Edwards Deming who says: “Eighty-five percent of the reasons [...] |
