WHAT IS LEAN SIX SIGMA?

Lean Six Sigma is a continuous improvement methodology that focuses on decreasing

lead time by reducing waste and variation. The reduction of lead time results in lower

operating costs, higher quality, and increased customer satisfaction.

Lean Six Sigma combines Six Sigma methodology and lean methodology that can be

applied in all types of organizations.

In addition, the reduction of variation makes a more predictable process, which yields

fewer defects and enables you to make more accurate forecasts.

By utilizing Lean and Six Sigma together, you can achieve more than what you could by

using one alone. This approach provides a wider array of improvement tools for you to

draw from and increases the probability for success.

The following table gives a quick comparison between Lean and Six Sigma, note that

the last element is common to both Lean and Six Sigma. They both require a change in

leadership and employee mindset to become a successful and sustainable program.
