The Big Lean Simulation Library

The Big Lean Simulation Library was created specifically to give Lean Six Sigma instructors an easy way to quickly demonstrate complex concepts to their students. The simulations are small and take between approximately 5 to 30 minutes to show. Each focuses on just a few concepts so you can show them interspersed throughout the class or all at once. They have different motifs (manufacturing, healthcare, back office work, etc.) so you could present different sets of simulations depending on your audience.
