To identify the origin of strategy, it is necessary to define strategy. According to Lawrence Freedman in his book Strategy, A History, the origins of strategy can be traced back to the beginning of time. The primary emphasis in the definition of strategy is first on the need to have a plan and second on the ability to behaviorally adapt. If the emphasis is placed on determining the ends and little effort is placed on looking at the ways or means, then the effectiveness of the strategy is likely to be limited. Many stories in the Bible are based on conflict where there is some level of thinking and influence needed to ensure a particular outcome is achieved. The theory of evolution includes the use of strategy as well and is supported in studies on chimpanzees from Frans de Wall and Jane Goodall. Business strategy evolved from the military in times of conflict.
