Strategy is a word which was first used by the military. It comes from an ancient Greek word for the general officer commanding all the armed forces of a state. A strategy is a long term plan on what to do to achieve a certain goal. When talking about the near future, people often use the word "tactics". Military theorist Carl von Clausewitz said "tactics is the art of using troops in battle; strategy is the art of using battles to win the war". Today, the word "strategy" is in common use; people might talk about "business strategy", for example.
