My company's Lean Training consists of about an hour of Lean overview and then two 3 hour sessions of applying Lean.
The hands-on consisted of three sessions where a bogus company was set up with suppliers and customers. The company made Lego PCBs. Each partcipant was given a job. Some were suppliers, some were customers, others had specific roles in the manufacturing process, like material handler and final inspector. We were given a specific period of time to produce product to customer orders.
In the first session, the pre-ordained process (set up by the trainer) is inefficient and the participants work like crazy but are unable to meet customer needs. At the end of the first session, participants score themselves on on-time delivery, product quality, through-put time, number of employees and square footage used.
In the next session, the participants (same jobs) were allowed to set something up on their own. Predictably they fixed many of the inefficiences and scored better.
In the last session, the trainer set up an optimal Lean operation, using many of the principles taught in the 1 hour classroom lecture, and it always yields the best results.
People enjoy the class and go back to their work with a new view of their work flow. It's very hands-on, with lots of energy.
