Training "Lean : keys to Good Lean and traps of Bad Lean" (in French)

All manufacturers are "already doing Lean" and in the vast majority of cases, the results are disappointing, both financially and in the actual practices of the tools and principles, i.e. the "philosophy" or Lean culture. Yet the company that « invented » Lean – Toyota Motor Company – continues to outperform its competitors all over the world. For instance, in France, the Toyota Motor Manufacturing France (TMMF) car assembly plant continues to be profitable and growing thereby demonstrating the power of « good Lean ». The purpose of this training is to enable companies who are disappointed with their Lean program to understand the reasons for its failure, and to be able to identify the keys to "good Lean" and how  to avoid the pitfalls of "bad Lean". Lean is not and should not be a fashion; the leaner a company is, the better.

To understand the key success factors of Toyota, Marris Consulting has the honour of welcoming Reynald Debaut-Henocque, ex-Senior Vice President of Manufacturing of Toyota Motor Manufacturing France to co-host this session. He has experienced first-hand the development of Toyota’s manufacturing in France since 1999. He will explain the Toyota way or “good Lean” during two thirds of this one-day session. Philip Marris will complete the picture by presenting the “bad Lean” practises that he has observed based on his over 30 years experience in over 250 companies.

The goal of this training session: to help organisations improve their performance by understanding both “good Lean” and “bad Lean” so that they can adjust, build or rebuild their Lean efforts and get closer to the results obtained by Toyota.

How to launch, continue, revive or accelerate ones Lean initiative?
