Lean is the biggest con game in the history of manufacturing. Everyone runs with this notion of a tool kit and boom they will be efficient. Really! Here is the kit; 5S (Elaborate cleaning process to shadow box everything), JIT (drive inventory to unsustainable operational levels), Kan-ban (manual paper or bins exchange of inventory to control inventory), and the infamous Kaizen teams (grouping of non-expert experience people waisting time with endless meetings), Visual line balancing and controls (I want begin to tell how much of a cluster-F you will be with that tool). Many companies have modified Lean to make it work since it does not work.If Lean and TPS is so great then why has Toyota abandon Lean for, once again, the American manufacturing process, precisely Ford motors process again? It was Toyota that sought Ford motor's process in the first place.
