What is Lean Six Sigma

Lean originated at Toyota in the ’40s and Six Sigma originated at Motorola in the ’80s. Although they’ve been taught as separate methods for many years, the line has dimmed and it’s now common to see Lean & Six Sigma teachings combined in order to produce the best of both areas.

Lean Six Sigma is a combination of two popular Continuous Improvement methods—Lean and Six Sigma—that take any organization towards operational excellence.

Although Lean and Six Sigma are different processes, they are complementary and share many similarities that allow them to flow together seamlessly.

Lean uses the PDCA—Plan-Do-Check-Act/Adjust—method and tools like 8 Wastes and 5S to achieve continuous improvement.

Six Sigma uses the DMAIC— Define-Measure-Analyze-Improve-Control—method and tools like Control Charts and risk management tools like Failure Modes & Effects Analysis (FMEA) to achieve continuous improvement.

To successfully implement Lean Six Sigma, a combination of tools from both lean manufacturing and Six Sigma must be used. Some of these tools include kaizen, value-stream mapping, line balancing, and visual management.
