The core of strategy work is always the same: discovering the critical factors in a situation and designing a way of coordinating and focusing actions to deal with those factors.

A leader’s most important responsibility is identifying the biggest challenges to forward progress and devising a coherent approach to overcoming them. In contexts ranging from corporate direction to national security, strategy matters. Yet we have become so accustomed to strategy as exhortation that we hardly blink an eye when a leader spouts slogans and announces high-sounding goals, calling the mixture a “strategy.

Unless leadership offers a theory of why things haven’t worked in the past, or why the challenge is difficult, it is hard to generate good strategy.

Leadership inspires and motivates self-sacrifice. Change, for example, requires painful adjustments, and good leadership helps people feel more positively about making those adjustments. Strategy is the craft of figuring out which purposes are both worth pursuing and capable of being accomplished.

... every organization faces a situation where the full complexity and ambiguity of the situation is daunting. An important duty of any leader is to absorb a large part of that complexity and ambiguity, passing on to the organization a simpler problem—one that is solvable. Many leaders fail badly at this responsibility, announcing ambitious goals without resolving a good chunk of ambiguity about the specific obstacles to be overcome.

Entropy makes it necessary for leaders to constantly work on maintaining an organization’s purpose, form, and methods even if there are no changes in strategy or competition.
