Which term refers to very specific actions that can be adapted as plans evolve?

The term that describes very specific actions that can be adapted as plans evolve is "tactics." Tactics are the actionable steps taken to achieve strategic objectives. In the context of public relations, tactics can involve specific communication actions, such as a social media post, a press release, or an event, that can be modified based on the effectiveness of the overall strategy or in response to external factors.

Tactics are generally more short-term and detailed compared to strategies, which outline broader goals and visions. Techniques and methods, while related, might not capture the adaptability focus that tactics do; techniques often refer to the skillful means employed to achieve tasks, whereas methods indicate overall procedures or approaches. Therefore, tactics are distinct in that they represent concrete actions that can change and adjust as circumstances dictate, making them the appropriate answer to this question.
