The concept of a Gemba walk comes from TPS, the Toyota Production System. Simplistically, the Japanese word Gemba refers to the site or the workplace. A Gemba walk involves a leader going to the workplace for accurate information rather than sitting in an office or conference room making changes without knowing what is happening in the real world.
I think it's pretty hard to argue that there's a shortage of content when it comes to OpEx. In fact, I recently ran an Amazon book search on the topic and found close to 1,400 distinct titles. When you consider all of the websites and LinkedIn groups dedicated to OpEx, the amount of material available quickly becomes hard to comprehend.
OpEx is not a black box. In reality, it’s often an open floor plan with low-rise cubicle walls and everything visible. This is good. We don’t want to have our clients toss a problem to us and turn their backs to focus on what is really important to them while we solve the problem in a dark corner. We are looking for a shared partnership for operational excellence programs.
