“The toughest and most basic challenge for companies that want to learn from Toyota is how to create an aligned organization of individuals who each have the DNA of the organization and are continually learning together to add value to the customer. It seems that whatever the starting point of discussions of lean transformation, we end up talking about culture. Perhaps this is an indication that culture is at the root of everything I have been discussing.”
