Six Sigma certification is a confirmation of an individual's capabilities with respect to specific competencies. Just like any other quality certification, it does not indicate that an individual is capable of unlimited process improvement, just that s/he has completed the necessary requirements from the company granting the certification.
For instance, millions of people have applied for, tested and been granted a driver's license in the India. It certifies that a person has passed the minimum guidelines and requirements for driving. The individual must pass both a written and hands-on driving test in order to 'certify'. Not all individuals in the India, however, have the same proficiency in driving - even though they may have passed the tests and been granted a driver's license. The same is true for Six Sigma certification. Certification alone does not summarize the worth of a true quality professional.
