ISO 17258:2015 describes a methodology for establishing the level of quality, performance, and productivity of processes, products, and services according to Six Sigma principles. It is applicable to all sectors (industries, services, administration, etc.) and to all types of organizations, whether it is already involved in an improvement programme such as Six Sigma, Lean, or not. In particular, it can be used to initiate a Six Sigma programme by providing a selection of improvement projects.
NOTE. The focus of this methodology is on criteria, measures, measurement process, and comparison process. The results can then be used to identify good practices of benchmarking.
