Certeau links “strategies” with institutions and structures of power who are the “producers”, while individuals are “consumers” acting in environments defined by strategies by using “tactics”. In the influential chapter “Walking in the City”, Certeau asserts that “the city” is generated by the strategies of governments, corporations, and other institutional bodies who produce things like maps that describe the city as a unified whole.
Certeau uses the vantage from the World Trade Center in New York to illustrate the idea of a panoptic, unified view. By contrast, the walker at street level moves in ways that are tactical and never fully determined by the plans of organizing bodies, taking shortcuts in spite of the strategic grid of the streets. This concretely illustrates Certeau’s argument that everyday life works by a process of poaching on the territory of others, using the rules and products that already exist in culture in a way that is influenced, but never wholly determined, by those rules and products.
