As Lean consultants, our approach to Lean in manufacturing revolves around developing a leadership team, managers, supervisors, etc. that drive the Lean implementation with new leadership systems. Once the leaders of the organization are driving Lean, the culture will naturally begin to change. The leaders must drive and support a shift into a problem solving culture. Only once a problem solving culture has begun to evolve can the Lean tools and processes be put to their full use and create astounding results.
