In order to support the promotion of our key strategy, three activities/actions that could be developed are as follows:
1. Develop a detailed customer engagement plan: A well-crafted customer engagement plan is essential in order to accurately target and reach potential customers. This should include tactics such as targeted advertising campaigns, social media outreach and collaborations with influencers who can help spread the message about our product or service.
2. Invest in research & development: Allocating resources towards researching and developing new products or services is one way to ensure that we stay ahead of any potential competitors. This investment will also help drive innovation which will help promote our brand image and boost market share over time.
3. Leverage existing partnerships & relationships: Utilizing existing relationships with partners or other organizations can be an effective way to get the word out about our business without having to expend too many resources in doing so; this could involve anything from sponsoring events to sponsoring content on other websites or apps.

Overall these activities provide a comprehensive approach for promoting our key strategy while still allowing us to remain flexible enough to quickly react when needed; by taking all these measures into consideration we should be able to create an effective promotional campaign that maximizes successes while minimizing risks going forward.
