It’s a set of tools to help us work in a better, faster and effective way.

Sigma is measured by defects per million opportunities.

By using six sigma, we try to reduce defects in a product, defective products, variance of any process outcomes and so on.

using tools of six sigma, we try to improvise the existing processes in terms of resources, returns and risk.

Also we try to find out issues for which we do not know the original or root cause. Or in many cases we may not even be aware of the exact problem!
