Business has only two functions — marketing and innovation. - Peter Drucker

The three most charismatic leaders in this century inflicted more suffering on the human race than almost any trio in history: Hitler, Stalin, and Mao. What matters is not the leader's charisma. What matters is the leader's mission.

DuPont, for 130 years, had confined itself to making munitions and explosives. In the mid-1920s it then organized its first research efforts in other areas, one of them the brand-new field of polymer chemistry, which the Germans had pioneered during World War I. For several years there were no results at all. Then, in 1928, an assistant left a burner on over the weekend. On Monday morning, Wallace H. Carothers, the chemist in charge, found that the stuff in the kettle had congealed into fibers. It took another ten years before DuPont found out how to make Nylon intentionally. The point of the story is, however, that the same accident had occurred several times in the laboratories of the big German chemical companies with the same results, and much earlier. The Germans were, of course, looking for a polymerized fiber — and they could have had it, along with world leadership in the chemical industry, ten years before DuPont had Nylon. But because they had not planned the experiment, they dismissed its results, poured out the accidentally produced fibers, and started all over again.

The job is, however, not to set priorities. That is easy. Everybody can do it. The reason why so few executives concentrate is the difficulty of setting “posteriorities” — that is, deciding what tasks not to tackle — and of sticking to the decision.
