Before we get into the principles, let’s have a brief of Lean Six Sigma;

“Lean Six Sigma is a fact-based, data-compelled idea of upgrading that values fault prevention over fault detection. It pushes customer satisfaction and bottom-line results by decreasing difference, waste, and cycle time while promoting the use of work regulation and flow, thus creating a competitive lead. It applies wherever variation and waste exist, and every worker should be involved.”

Lean Six Sigma is an influential, proven technique for improving business productivity. Concisely, here are the key principles of Lean Six Sigma business transformation:

  • Be customer-centric.
  • Identify and comprehend how the work gets done (the value stream).
  • Manage, improve and smooth the progression flow.
  • Eradicate Non-Value-Added steps and waste.
  • Manage by fact and reduce variation.
  • Involve and prepare the people in the process.
  • Accept improvement activity in an orderly way.


The principle of Lean Six Sigma helps to improve the efficiency and quality of the process.
