There are times when we cannot comprehend an obvious problem that is right in front of the eye. There are also times when the same set of data is interpreted differently by two sets of people. Lean practitioners conclude that it is because our brain is not into reality.
Although occasions of brain not being in reality is necessary for survival, it is certainly not considered to be a quality, when the organization faces a convoluted risk. The fact is that our brain is certainly not evolving as fast the world around us. Which is why our conventional beliefs, sometimes, come in the way of taking the best decisions.
PDCA (Plan-Do-Check-Act) is an established method that helps overcome this issue. PDCA inculcates the culture of gaining agreement on the plausible explanation that what we think is right. For a current value stream map or even for a future state map, Lean experts preach the principle of ‘respect for people’.
