Lean Six Sigma combines two well-known approaches to the practice of continuous improvement. 

The 'Lean' component of Lean Six Sigma focuses mainly on the elimination of waste and non-value-added activities in a process. By eliminating waste, Lean helps to reduce process leadtimes, inventories and ultimately costs.

The 'Six Sigma' component focuses more on the elimination of variation in a process. Many quality problems and defects are rooted in unstable processes or processes with excessive variation. By tackling variation, the Six Sigma methodology helps to resolve complex quality problems, reduce defects and improve process capability. Statistically, a process operating at Six Sigma level is one that generates only 3.4 defects per million opportunities.  

 Focus of Lean Six Sigma

Lean Six Sigma combines the effect and power of two key strategies:-
	•	The focus of Lean is to reduce lead time and control costs
	•	The focus of Six Sigma is to improve quality and reduce costs.

A Value Based Approach

The Lean Six Sigma continuous improvement process is a value-based approach. Improvement opportunities are identified by carefully listening to the voices of our customers, employees and processes. These opportunities are screened through using value-based criteria, prioritized and finally assigned to project teams led by trained experts. These experts are referred to as Black Belts or Green Belts. Under the leadership of the Black Belt or Green Belt, these teams applies a rigorous D-M-A-I-C problem-solving approach to come up with breakthrough solutions.
