Lean Workout

Also known as a Kaizen event, it is an extended meeting (often lasting 1 to 5 days) that focuses on improving processes using Lean tools and concepts. It usually includes all stakeholders that are critical to the process being improved. The goal of the workout is to design an improved process with either it fully implemented or at least a defined implementation plan.
