Six Sigma

Today most European countries find themselves still struggling within the storm of financial and social crisis. Nevertheless, it is quite amazing how many tools and methodologies were available before and after, that could help avoid the sequences of

  • Bad Management,
  • No Control,
  • and missing  Systemic Corrective Procedures.

Six Sigma is one of the most known and proven Business Management Strategies.
Six Sigma isa Business Performance Methodology, widely adapted and used, by most successful companies and organizations.
Six Sigma has been already used to improve results within companies/organizations, regarding quantity and quality of products and services.
Its purpose is to eliminate defect products, identify problems in current processes and procedures,
and apply the changes necessary to improve the quantitative and qualitative outcome.

With Six Sigma, finally, there should be no room for error or failure. Six Sigma is, almost perfect products and services.

A given process, should deviate from perfection, the less possible.
By the Six Sigma concept, since one can measure process failure and product defects, in a quantitative and qualitative way, then it is possible to eliminate them.
For Six Sigma Quality, there should be less than 3,4 defects/million, or a 99.99966% overall success. This means that non-acceptable results, results that do not meet required specifications should be completely eliminated.

Six Sigma is also a parallel to DMADV and DMAIC methodologies


  • DMAIC:         Define, Measure, Analyze, Improve, Control
  • DMADV:        Define, Measure, Analyze, Design, Verify

Six Sigma concepts include:

  • Quality:                is Critical
  • Defect:                 Bad products are unacceptable, since clients require quality
  • Capability:          whatever is delivered by business processes
  • Variation:            Customer specific results
  • Operations:        Consistency and predictable results as an outcome of that improve anything that customers observe and demand

Six Sigma has been conceived and used by Motorola in 1986. It became widely known after used as a business strategy from General Electric in 1995.  
Now Six Sigma is used world - wide in many different business areas and industries.
The term Six Sigma can be found from the German Mathematician Carl Frederick Gauss -1777 to 1855-.
Carl Frederick Gauss published “Theoria Motus Corporum Arithmeticae” in 1809 where he introduced the concept of the bell curve.

The Symbol of Six Sigma is found in 1920, where Walter Shewhart showed  three sigma, as the point where processes require corrections.

The inspiration of Six Sigma, comes from quality improvement methodologies, TQM, zero defects methodologies that have been initially captured and applied 70 years ago, by superb minds like Juran, Deming, Shewhart, Taguchg and Ishikawa.   Finally,

Six Sigma in nothing else than extreme cost savings, effectiveness and accuracy.
