How are Lean and Six Sigma different?
• One way to explain the difference is to compare Leans approach of inch-deep, mile-wide to Six Sigmas approach of inch-wide, mile-deep. • Lean and Six Sigma are most effective and complementary when applied together to produce both incremental and breakthrough results. Lean focuses on eliminating non-value added activity and process steps: eliminate unneeded steps and inventory to reduce flow times and inventory turns. Six Sigma focuses on reducing variation from value-added process steps remaining: increase process capability and yield.
