In Lean Production training and education, simulators are often used. These can take the form of for instance desktop games, computer simulations, or full-scale simulators. Most evidence of training transfer from the training environment to the work situation is anecdotal, and as such is assessment of training transfer a research gap. Experiences from training sessions in Karlstad Lean Factory^® are presented, including a combination with computer simulation. A unified model for learning and improvement work is presented. Some suggestions for future work include investigating synergy with Smart Manufacturing and/or innovative product realization.
