Which of the following is not part of collaboration in action?

Collaboration in action typically involves several vital components that facilitate effective communication, decision-making, and coordination among stakeholders. Meetings and briefings are foundational to collaboration as they provide a structured environment for information sharing and strategy development. Community engagement is essential for ensuring that the needs and perspectives of the population are considered, which enhances the quality and relevance of the collaborative efforts. Joint assessments are crucial as they involve gathering and analyzing data cooperatively, ensuring that all parties have a shared understanding of the situation.

In this context, the term "XYZs" does not represent a recognized element or standard practice in collaborative efforts. Without context, it appears to be an arbitrary or undefined term that does not align with the established processes of collaboration. Thus, it stands out as not being part of collaboration in action, making it the correct choice in this question.
