Which communications management practice includes specifying all of the communications systems and platforms that parties will use to share information?

The concept of specifying all of the communications systems and platforms that parties will use to share information falls under the practice of agreements. Agreements are essential in establishing a clear framework for collaboration between various entities during an incident. By defining the communication systems and platforms through which information will be shared, stakeholders ensure that everyone is on the same page, improving interoperability and reducing the chances of miscommunication.

In the context of incident management, effective communication is crucial to coordinate efforts, especially during emergencies where multiple agencies might be involved. Agreements typically provide the necessary guidelines that detail which systems (e.g., radios, email, or specific software applications) will be employed, ensuring that all involved parties understand and adhere to the established procedures.

While protocols refer to the rules and practices that govern how communication occurs, they do not specifically encompass the contractual or formal agreements that set up the systems and platforms themselves. Commands are more related to directives issued within the ICS structure, and strategies refer to overarching plans to achieve incident objectives rather than communication specifics. Hence, the focus on agreements highlights the importance of establishing mutual understanding of communication methods among all stakeholders.
