Auditing & Strategy.


The ISO 18404:2015 International Standard defines the competencies for the attainment of specific levels of competency with regards to Six Sigma, Lean, and “Lean & Six Sigma” in individuals, e.g. Black Belt, Green Belt and Lean practitioners and their organizations. Yellow Belt is not included in this International Standard. This International Standard excludes Design for Six Sigma.

If your organization has started the journey in “Lean & Six Sigma” and would like to gain knowledge through a gap analysis or a formal audit against the standard criteria then call us today.

There has been much debate on the nature of Six Sigma and Lean, their commonality and their differences. Professionals have argued over the content, overlap, application, supremacy and purpose of the two approaches, or a combination of the two approaches, many under the umbrella title of “Lean Six Sigma”. Six Sigma and Lean have a commonality of field of application, i.e. process improvement; the use of such tools can be integrated very nicely with quality management systems, such as ISO 9001 and ISO 13485 to help with their improvement strategy.

This International Standard therefore sets out the separate competency requirements for Six Sigma and Lean implementation; it also sets out a combined competency framework for “Lean & Six Sigma”. In so doing, it focuses on the competencies (skills and abilities) to deliver benefits to an organization rather than defining the specific educational level required for each role.
