The six sigma way, we will use and refer to a five-phase improvement cycle that has become increasingly common in six sigma organizations. Six sigma is based on DMAIC Model. Processes in Six Sigma are documented, communicated measured and refined on an ongoing basis. Boundary less collaboration, featuring cooperation, between internal groups and with customers, suppliers, and supply chain partners.

Define phase

  • Identify the problem
  • Define Requirement
  • Define goal / change vision
  • Set Goals
  • Clarity scope & customer requirements

Measure phase

  • Validate problem / process
  • Measure performance to requirements
  • Refine problem / goal
  • Gather process efficiency data
  • Measure key steps / input   


Analysis phase

  • Identify Best practices
  • Develop Causal hypotheses
  • Assess process design
  • Validate hypothesis
  • Identify Vital few Root causes   
  • Refine requirements


Improve phase

  • Develop Ideas to remove root cause
  • Design new process
  • Test solutions
  • Implement new process structure,What is a meaning of Six Sigma's DMAIC Model? Articles systems
  • Standard solution measure results


Control phase

  • Correct problem as need

Six Essential Features of Six Sigma:

  • A genuine focus on the customer, backed by an attitude that puts the customers' need first, as well as by systems and strategies that serve to tie in the business to the "Voice of the Customer".
  • Data and fact driven management, with effective measurement systems that track both results and outcomes (Ys) and Process, input, and other predictive factors (Xs).
  • Process focus, management, and improvements, as an engine for growth and success. Processes in Six Sigma are documented, communicated measured and refined on an ongoing basis.
  • Proactive Management, involving habits and practices that anticipate problems and changes, apply facts and data, and question assumptions about goals and " how we do things".
  • Boundary less collaboration, featuring cooperation, between internal groups and with customers, suppliers, and supply chain partners.
  • A drive for perfection and yet a tolerance for failure that gives people in a Six sigma organization the freedom to test new approaches even while managing risks and learning from mistakes, thereby "raising the bar" of performance and customer satisfaction.
