Lean Six Sigma

What is Lean Six Sigma?

Lean Six Sigma

Lean Six Sigma is the combination of two process improvement methodologies: Lean and Six Sigma.


Known best from its use at Toyota, Lean is the reduction of waste in any process in order to maximize profit and reduce costs. 
The goal of Lean is to improve and control process.

Six Sigma

Brought to the forefront by General Electric, Six Sigma is used to find and eliminate process variation.
Six Sigma steps are known as DMAIC:

  • Define the problem
  • Measure through data collection
  • Analyze the process
  • Improve the process
  • Control the process

Combining Lean and Six Sigma

Lean is such a good fit with Six Sigma that it is now taught through the various levels of Six Sigma certification, including Green Belt and Black Belt. Lean Six Sigma is the approach used by Selsius™ trainers and consultants when assisting our clients with continuous improvement work.
