What is strategy?

For me, strategy is an overarching approach towards some goal. It considers the overall situation and gives some direction. It is not a detailed plan, but a roadmap, a set of guiding principles. It is about defining what is important and what can be neglected.

Here are a few definitions I found on the web:

Strategy is where you will focus your efforts to achieve your goals, and how you will succeed—or, “where to play and how to win.” It defines a specific course of action that will take you from where you are now to where you want to be. ⇽ BrainTraffic

Strategy is making trade-offs in competing. The essence of strategy is choosing what not to do. ⇽ HBR

Strategy […] is a general plan to achieve one or more long-term or overall goals under conditions of uncertainty. ⇽ Wikipedia
