Six Sigma ISO standards (ISO 13053, part 1 and 2) :

The documents :

  1. Quantitative methods in process improvement - Six Sigma - Part 1 : DMAIC method
  2. Quantitative methods in process improvement - Six Sigma - Part 2 : Tools and techniques

have been updated from the numerous comments (More than 200) received during the DIS voting procedure. Countries such as United States, United Kingdom, Germany, Japan, Mexico, Czech Republic, France, China, India...have contributed to those comments.

These documents are to become ISO standards in a near futur.

These two documents are going for FDIS ballot.

Response Surface Methodology (RSM) :

The document was renamed by "Selected illustration of Response Surface methodology - Part 1 : Central Composite Designs". It is to become an ISO Technical Report (TR). 

Some issues shall be solved with:

  • reformulating the objectives of the experiment (identify factors, shape of response, optimize...),
  • detailing how to handle the independance of factors (what to do when 2 factors are not independant ?).

Selected illustration of Contingency tables :

This new subject is to drive to the publication of an ISO/TR (ISO/TR 16705) on Table of Contingency.
