After reading Chapter 6 on Lean Systems, one obvious take away is that a huge component of successful Lean implementation is teamwork. A case could be made that Lean systems work better in some cultures than in others, depending how that culture values the collective. In essence, it comes down to Teamwork vs. Autonomy. For example, you could make a statement that Toyota is very good at Lean systems because Japanese culture traditionally values the collective over the individual. Think about a culture that you are familiar with and give your opinion on if you think that a Lean System would fair well there and why. A culture could be from a company, school, city, state, country, region, etc.
