Lean (Lean Manufacturing)

  • “How does someone become Lean certified?”

  • “Which is more preferred… Lean Green Belt or a Lean Black Belt?”

  • “Where might I go to get some free Lean training?”

  • “Is Lean Six Sigma Certification the same as Six Sigma Certification?”

  • “Can I complete my Lean training online?”

These are some of the many questions we receive and respond to each day at Lean Six Sigma Coach.  Continuous flow, just in time (JIT), value streams, push versus pull, kaizen, and muda (aka “waste”)… If you are familiar with any of the preceding terms, then chances are you have already been exposed to Lean or Lean Manufacturing.

What is Lean?

The Lean Enterprise Institute offers a great definition for Lean:  “The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources.

By focusing on key concepts such as continuous flow and the elimination of any waste in processes, Lean and associated principles, tools, and methods enables organizations to assess their current state value streams, from customer demand to demand fulfillment, and design and implement future state value stream that can be best described as transformative change and improvement.

Lean also describes an organizational culture, from boardroom to front line operations, where everyone not only understands the principles of Lean but also participate in promoting Lean Thinking and engaging in continuous improvement, including “kaizen”… change for the better.
