Who is the thinker in this photo? How might he be helpful to us?
a: H. Edwards Deming
Deming, an American engineer and mathematician, is generally regarded as the founding thought leader of Quality, Total Quality Management, Lean, Six Sigma and associated notions of change and strategy. He was instrumental in Japan's "Economic Miracle" of the 1950s and 60s. His work with math/stats in measuring business processes and human behavior has been monumentally impactful (good and bad) in the history of management.
Good: breaking behavior down to measurable activities which can be tracked and -- in theory -- improved
Bad: the cold effect on culture and human interaction; the notion that human experience can be reduced to measurable bits that reassemble to form a coherent body, IE a critique of reductionism
https://en.wikipedia.org/wiki/ReductionismTo his credit, he attempted to combine rational use of numbers AND a respect of culture and psychology. We may argue that rational oriented managers have overused his discussion of stats and metrics while discarding elements of culture and leadership they felt too unwieldy. Be careful with numbers; an over-reliance on them creates the conditions for "it's just business" type of ethics in decision-making, as if the numbers are more important than the people who create them.
Personal tangent if interested: Deming's ideas greatly impact the way the US fights wars. This was perhaps most visible during the Vietnam experience. James McNamara, then Secretary of Defense, was well known to view the war through stats: number of enemy killed, bombs dropped, etc. In military circles, the modern notion that one can "win" a conflict by measured destruction of the enemy comes from him. In my military life, we study this constantly; I am not sure it's the best way to understand the extremely (perhaps most) complex human phenomenon that is war.
