Six Sigma Process

Six Sigma is a rigorous team problem solving methodology based on statistical analysis of data. Six Sigma, often associated with DMAIC, is successful by precisely defining the problem, measuring its occurrence and effects, analysis of data to determine root causes and improving the process so the problem never comes back.

DEFINE - define project scope and goals, gain knowledge about the process and the client
MEASURE - gather information about current process performance
ANALYZE - identify root causes of the problem and confirm them with data
IMPROVE - develop, verify and implement solutions that will eliminate or reduce the effects of root causes
CONTROL - maintain improvement by standardizing work methods and processes

The name Six Sigma comes from the Greek alphabet and is used by mathematicians to describe a standard deviation. A process, whether it is fabrication of widgets or bank money transfer, operates on a Six Sigma level if the distribution of its results falls within 6 standard deviations on each side of the average. Such process, according to statistics, on average produces only 3.4 defects per million opportunities. For a customer, it means that the product or service is realistically free of defects. 



Every potential project must fulfill three conditions:

  1. There is a gap between current and desired process performance
  2. The root cause of the problem is not clearly understood
  3. The solution is not predetermined nor is the optimal solution known
