But is this statement really true? Does starting a Six Sigma initiative automatically mean you’ll have an effective Quality management system? Definitely not. The downside of this methodology is that there are currently no “standards”, nor an “official” certifying institution. There is no external body that checks whether everyone walks the talk.
Six Sigma is more than starting a few projects, training some Belts and educating some business leaders about what it all means. The Six Sigma criteria depend on the business implementing this approach.
The Criteria
Phase 1: Enthusiasm & Awareness

This phase also includes the first Black Belt/Green Belt trainings. If the projects only focus on manufacturing areas, the company will limit themselves to the playground of traditional Quality improvement initiatives. Instead, it makes sense to think cross functionally and recognize improvement opportunities in all key business processes.
Phase 2: Seeking Results
Phase 3: Implementing Measures
Phase 4: Implementing Six Sigma As BAU
Six Sigma In The Bloodstream
Consequentially, you will know when Six Sigma is in the bloodstream of your organisation, when it will no longer be necessary to talk incessantly about it. Then, it will be part of the culture. This is probably one of the major differences between earlier improvement efforts such as TQ and Six Sigma. There will be no need to get startled by the call of the ISO 9000 auditor asking for the date of the re-certification. Six Sigma is a different mindset. There will rather be a kind of a regular internal evaluation by the leadership team assessing the status of their own management system – comparable with EFQ assessment.
- Incorporating customer requirements into business processes,
- Integrating business management skills into each element of the organisation effectively,
- Analysing causes of process and output variation with statistical and non-statistical tools systematically,
- Instilling people with the ability to get involved, and initiate, their own improvement projects cross-functional and company-wide,
- Tracking performance honestly over time.
