Lean Manufacturing Implementation Program What is Lean Six Sigma? Lean is an approach that seeks to improve flow in the value stream and eliminate waste. Six Sigma uses a powerful framework (DMAIC) and statistical tools to uncover root causes to understand and reduce variation. A combination of both provides a structured improvement approach and effective tools to solve problems. This creates rapid transformational improvement at lower cost. The root of both Lean and Six Sigma reach back to the time when the greatest pressure for quality and speed were on manufacturing. Lean rose as a method for optimizing automotive manufacturing; Six Sigma evolved as a quality initiative to eliminate defects by reducing variation in processes in the semiconductor industry. It is not surprising that the earliest adopters of Lean Six Sigma arose in the service support functions of manufacturing organizations like GE Capital, Caterpillar Finance, and Lockheed Martin. Lean Six Sigma for services is a business improvement methodologythat maximizes shareholder value by achieving the fastest rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. The fusion of Lean and Six Sigma improvement methods is required because:
Ironically, Six Sigma and Lean have often been regarded as rival initiatives. Lean enthusiasts note that Six Sigma pays little attention to anything related to speed and flow, while Six Sigma supporters point out that Lean fails to address key concepts like customer needs and variation. Both sides are right. Yet these arguments are more often used to advocate choosing one over the other, rather than to support the more logical conclusion that we blend Lean and Six Sigma.
Lean:
The two methodologies interact and reinforce one another, such that percentage gains in Return on Investment Capital (ROIC%) are much faster if Lean and Six Sigma are implemented together.
