Six Sigma is much more than just a way of thinking about process improvement, and the DMAIC framework. There are a large number of tools which can help you on your projects, to get the analysis and improvements that your company needs.
These are a series of tasks to follow to make up a whole project:
- DMAIC – the main process improvement framework
- Design for Six Sigma (DFSS, DMADV) – a version of DMAIC for if a complete process rewrite from scratch is needed
Plan before action!
These are used to look at how the process operates now
- SIPOC / COPIS – process overview showing clearly the inputs and outputs, giving a quick summary
- Swimlane Diagrams – good for mapping linear (simple) processes between several departments
- Value Stream Maps – all actions from start to finish in the process
Useful for turning raw data into usable information and prioritizing issues.
- Pareto Analysis – statistically you can tackle most of a problem with a very small fraction of the time of
- Failure Modes and Effects Analysis (FMEA)
- 5S / CANDO – A Lean framework for keeping a workplace efficient
- Poka Yoke – You can easily remove issues by making them impossible to make or immediately obvious when they occur
If you don’t want to keep looking at Six Sigma lookup tables, you can change between DPMO (proportion of operations that end in error) and sigma level in excel:
I’m adding new tools all the time so if you want a specific one check back later or mention it in the comments.
