Whats the difference between Lean Six Sigma and other problem solving methods?
There are any number of ways to solve problems, some work better than others, however.The trial and error problem solving method, sadly still in use, is the equivalent of groping in the dark, with little or no data, little or no method and often little or no idea. The result, quite predictably is little or no improvement’.The Just do it’ method, where the problem solver is encouraged to jump straight into process changes, can be effective if the problem and root cause are understood and the person doing it knows what they are doing but the method lacks rigour and repeatability.More advanced methods such as CEDAC (Cause and Effect with the Addition of Cards) or 8D (Eight Disciplines) are more structured. These methodologies utilise simple and often subjective tools such as the Fishbone Diagrams and Pareto analysis, however, and lack statistical rigour. 8D for example is a useful method to employ when reacting to customer problems.Lean Six Sigma uses the DMAIC process of Define, Measure,
