Quality management, TQM, Process Reengineering, Six Sigma, Lean Six Sigma. All of them belong to ONE thing. What is it?

These are the systematic process or tool which control the deviation in the process and ensure the quality work.

They are all components of " Continuous Improvement " or " Journey to Excellence "
