"corner solutions"

Neste postal  Conversas, chapadas, "o problema é do governo" e o problema do locus de controlo refiro a programação linear e uso esta figura:

Entretanto, na leitura de  "The Crux - How Leaders Become Strategists" de Richard P. Rumelt encontro a mesma metáfora:

"Strategies are usually what I call “corner solutions.” The phrase comes from linear programming, where the solution to a problem is normally a set of actions defined by the intersection of various constraints—geometrically, a corner of intersecting lines or planes. When the constraints are so strong that no solution is possible, I call the strategy a “null set.” There is no solution without relaxing at least one of the constraints.

...

The standard human response to a null set is to behave myopically, giving obeisance to whichever value is most salient at the moment.

...

To move out of the null, some constraints must be relaxed or removed. Some values held dear must be foregone. That probably entails a change in leadership. We expect our leaders to have firm resolve, but that very firmness becomes a liability when it impedes a change in priorities."
