Six Sigma Improvement

Project Detail

Six Sigma Improvement and Design for Six Sigma improve process effectiveness by reducing defects:

  • Thoroughly understand the process and the customer requirements;
  • Analyze data to identify root causes of defects (failure to meet a customer’s need);
  • Identify breakthrough solutions to reach a goal of near-perfection.

Six Sigma DMAIC fits best when:

  • Problem or gap in performance exists
  • Root cause(s) are unknown/unsure
  • “Band-aids” are unacceptable
  • Customer needs and requirements unclear

Six Sigma DMAIC Steps:

  • Define: understand the problem, process, & customer
  • Measure: quantify how well the process meets customer needs
  • Analyze: identify and confirm root causes of the problem
  • Improve: fix the problem
  • Control: monitor the process to ensure the problem stays fixed

Design for Six Sigma fits best when:

  • Process or product is new (does not exist); or
  • The problem is so bad that old process needs to be discarded
  • Customer requirements need to be well-defined
  • Resources are available for a detailed effort

Design for Six Sigma Steps:

  • Define: understand the problem, vision/goal, & customer
  • Measure: identify and quantify customer requirements
  • Analyze: thoroughly describe the design requirements
  • Design: create a “fully capable” process or product
  • Verify: ensure that the process will remain capable in the future
