Why lean six sigma?

[Sudharsan D]

Why lean concept and six sigma concept clubbed together?

 

[Vishwadeep Khatri]

Hi Sudharshan,

 

Traditionally, Lean tools were more popular in waste elimination and thereby reducing Lead Time (or turnaround time) while Six Sigma was associated with defects or variation reduction. It was observed that most processes need accuracy as well as speed. It made perfect business sense to blend the two toolkits so that trained professionals get exposed to both and do not achieve one objective at the expense of the other.
