To explain the concepts of hypothesis testing (null and alternative hypothesis statements), I use an example of James Bond. His famous line is "shaken, not stirred" when ordering a martini. In a hypothesis test, we would set the null (default) hypothesis to say that he cannot tell the difference. The alternative hypothesis would be proven if there was data showing he could tell the difference (better than guessing or chance). Hope this helps you understand the concept of hypothesis testing a lit...

In one of my recent Lean classes, I discuss the difference between planning kaizen events and working kaizen events. Planning events end up with a 90-day implemenatation plan. Working events end up with 80% completion of actions by the end of the event, with 30 days to complete the remaining 20% of the actions. I try and encourage more working sessions, but planning is sometimes really important to decide where to focus the working sessions in the future. To better understand this podcast, watch...

Traditionally, the multiplication of Severity, Occurrence and Detection was used to calculate a Risk Priority Number (RPN). Any number over a certain RPN threshold required action to reduce the risk.
