Many organizations are coupling these initiatives by looking at Six Sigma. Six Sigma techniques are an important tool in promoting process improvement.

The name, Six Sigma, is taken from the approach's statistical roots. If a product or process has a six sigma level of consistency, then it is experiencing only 3.4 defects per million. In other words, six sigma products and processes are 99.99966% consistent. In order to reach these results, Six Sigma efforts pursue the following five objectives:
  • Define the problem area in objective terms
  • Measure the performance of products and processes
  • Analyze the problems to identify root causes
  • Improve the results by redesigning processes and reducing variation
  • Control the processes to ensure the improvements are permanent
