A Strategy is “a detailed plan for achieving success in situations such as war, politics, business, industry, or sport, […]”.
(dictionary.cambridge.org)

A strategy is ‘how’ to reach your purpose/intent. Examples of strategies that were used by the Situationist are Détournement (Hijack), the Dérive and the temporary autonomous zones. More contemporary practices include safe spaces, flash mobs, ‘cancelling’, guerrilla marketing, adbusting, culture jamming and all sort of other interventions.

A strategy affirms, establishes, disrupts, questions, ridicules, celebrates, cancels or distracts us from a system of power.

Strategy is often used in the world of marketing and communication, basically referring to “a long-term, forward-looking approach and an overall game plan of any organization or any business with the fundamental goal of achieving a sustainable competitive advantage by understanding the needs and wants of customers. A marketing strategy is a broad strategy that encompasses everything from how a company positions itself, to the creative, the strategic partners, the media relations, the marketing mix, and the channels and tactics.” (source: mayple.com/blog/marketing-strategy).

The difference between a marketing strategy and a tactic is that “marketing strategies are broader than specific tactics. For example, a business could have a content strategy for their social media channels or for search engine optimization, and then they could have specific tactics they execute for each channel.” (source: mayple.com/blog/marketing-strategy).
