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
- 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
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:
