Six Sigma Practice Exam
Six Sigma refers to techniques and tools which are used for process
improvement to reduce defects and variability in business processes. It
uses statistical methods to identify inefficiencies and improve
processes quality level and performance. It aims to achieve a defect
rate of less than 3.4 DPMO (defects per million opportunities), thus
having a high quality level and consistency in products or services. Six
Sigma uses DMAIC (Define, Measure, Analyze, Improve, Control)
methodology which is structured to implement Six sigma in all stages of a
process.
Certification in Six Sigma attests to your skills
and knowledge in applying Six Sigma principles and methodologies to
improve business processes. This certification assess you in DMAIC,
statistical tools and techniques, process mapping , quality tools, and
lean six sigma.
Why is Six Sigma certification important?
