The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.
The McNamara fallacy, named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.
The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.
Most organizations use some version of an innovation funnel to bring ideas to life. It starts with lots of ideas at the front end and then launches whatever survives all the way to the back end.
Yet this Darwinian process of bringing ideas to life doesn’t necessarily lead to survival of the fittest ideas. If we’re not careful, the innovation funnel leads to survival of the safest ideas.
Organizations are good at spotting risks. In an effort to improve success rates, organizations tend to put sharper teeth in the funnel.
As ideas run the organizational gauntlet, they can get pruned, sheared, shaped, and watered down beyond recognition. On the way, they can lose the essence of the idea. They may lose their point of difference and reason for being.
