Hi Peter,As you know, I am from Asia having werkod in China, The Philippines, Singapore, and Taiwan. In these regions possesing such an advanced skill as Lean Six Sigma is a great asset, and I have witnessed or heard many companies implementing a strategy to train a first batch of employees and hoping to use them to train others. Unfortunately, most people immediately advertise themselves to consulting companies or even set up a company to provide consultancy service once they have reach certification. Those that stayed on, well they did not have the integrity to impart to the next batch 100% of what they learnt.I am not challenging your advice to companies to implement such skill training in batches, I am only advicing that companies must also implement checks and balances.Wish you all the best in your new book.
