Far too often, "Lean Sigma" training is basically regular Six Sigma training (a rigorous and oft-helpful statistical methodology) with just a handful of superficial Lean tools.
Lean is more than a bunch of tools. Lean is a philosophy and a management system.
When the Lean component of "Lean Sigma" training is limited to 5S, the types of waste, value stream maps, and spaghetti diagrams... that's very superficial.
Where is the talk of culture? Where is the discussion about leading differently? This is not Lean, it's just tools.
