Aim for "Effectiveness" in Your Gemba Walks, Not "Effi

This is an elaboration on something I originally posted on LinkedIn. I saw somebody touting an approach that would guarantee "maximum efficiency for your management gemba walks." Ah, the efficiency trap. Is efficiency really the goal here? Efficiency is usually defined as outputs divided by inputs. Visiting more departments more quickly would increase "efficiency." Shouldn't the goal there be "maximum effectiveness?"
