Strategy is a framework for decision making
The word ‘strategy’ has become popular across many areas of life. The word comes from the Greek ‘strategos’ which means ‘general’. Though it has military origins, it has been taken over by other realms in which there is conflict or competition, such as politics and business. In other contexts, a strategy often means something like a ‘game plan’, or ‘approach’. In business and politics, it is used very loosely when words like ‘policy’ or ‘objective’ might be closer to the mark.
Strictly speaking, a strategy is only needed in a very particular context – when you are trying to achieve a particular aim with limited resources against some form of opposition.
