Volkswagen builds its expensive Phaeton model in a factory with glass walls and hardwood floors by people in white gloves with parts delivered by robotic cart. All very high tech, but notice the number of times WIP and finished goods are handled and stored. They are proud of using a university to design the conveyor system, but I think they would have a more flexible, less expensive system (with more employee buy-in) if they had had someone facilitate the ideas of their own employees.
