The most important part of a leader's job is to set in motion the actions today that will build a better future tomorrow - in other words, strategy. But how do leaders become strategists?

In this ground-breaking book, Richard Rumelt, the world's leading authority on strategy, shows how finding the crux of a challenge is the essence of the strategist's skill. The crux is the key issue where action will best pay off, and Rumelt reveals how to pinpoint it so you can focus energy on what really matters.

Drawing on decades of professional and academic experience, and through vivid storytelling of some of the most important business decisions of recent times, Rumelt illuminates how leaders can overcome obstacles, navigate uncertainty and determine the best path forward.

Strategy is not about setting financial targets, statements of desired outcomes, or performance goals, it is about finding the crux and taking decisive, coherent action.
