Six sigma standards

The International Organization for Standardization has developed two standards on the 6 Sigma concept:

ISO 13053-1:2011 Quantitative methods in process improvement. Six Sigma Part 1: DMAIC methodology. This standard unifies the application of the 6 sigma concept and provides recommendations on the application of the DMAIC methodology during the implementation of six sigma projects. Also, this standard defines the procedure for managing 6 sigma projects, sets requirements for project participants, their roles and training requirements.

The standard applies only to projects for improve existing processes. This standard is not suitable for designing new processes (or redesigning), because the DMADV methodology (DFSS) has been developed in the 6 sigma concept for these purposes. The ISO 13053-1:2011 standard can be applied to organizations of any scope.

ISO 13053-2:2011 Quantitative methods in process improvement. Six Sigma Part 2: Tools and techniques - This standard represents the composition of 6 sigma tools and methods used at each stage of the DMAIC methodology. Also, the standard provides a summary of methods and tools.
