The Lean assessment for a factory, warehouse, or facility is a structured, in-depth evaluation of its operations aimed at identifying waste, improving efficiency, and maximizing customer value. The process begins with a review of current workflows to establish a clear understanding of the existing “current” state. The key to this approach are the Gemba walks—physically going to the place where work happens—to directly observe processes, distinguish between value-added and non-value-added activities, and engage frontline team members for meaningful insights and collaboration.
