A Macro That Writes Macros
Brad MorrowIf you are like me, you may find yourself writing a fair number of MS Excel macros to automate repeatable tasks.

Cartoons as Tools
Craig PlainPart 1 Looking at the team I saw their eyes were glazing over. I hate that.

Candidate Selection: Motivate the Best People to Choose Six Sigma
Michael CarverIt is an old dilemma. Should we select our Black Belt candidates based on prior performance in unrelated jobs or should we allow people to self-select for Black Belt roles based upon motivation and aptitude? Unfortunately, the answer is clearly, “It depends.” There are advantages to each approach and each approach has specific perils. When…
How Much Training Is Needed to Create Good Black Belts?
One would think that with the levels of standardization and process efficiency we drive in Lean Six Sigma that there would be consensus on how much training a certified Black Belt should receive.

Cold Beer
Erik ChristensenI have to admit this is one of my favorite subjects – beer! Recently I toured the Ellis Island Casino and Brewery in Las Vegas.
