I've recently read a book about Six Sigma. It seems that this approach is very much oriented towards customers and providing customer value. This means that the quality related to the customer value is the main focus of Six Sigma.
Another important observation is that the following parts are similar to the approach of ours:
- the flow diagrams
- the CTQ and the need for control/monitoring
- the use of Run-charts and Pareto Diagrams.
An open issue is how exactly we can make sure that our approach is compliant with Six Sigma. That is the subject for the next paper.
