Which communications management practice specifies the systems and platforms for sharing information?

The practice that specifies the systems and platforms for sharing information is agreements. In the context of communications management, agreements outline the protocols for how information will be shared among various stakeholders, including the channels to be used, the frequency of communication, and the types of data to be shared.

Agreements are essential in establishing a common understanding and ensuring that all parties involved are aware of their roles and responsibilities regarding information exchange. This can include formal memorandums of understanding, contracts, or any other document that sets forth specific expectations for communication.

On the other hand, protocols typically refer to the methods or procedures to be followed during communication but do not specify the platforms or systems for sharing information. Guidelines serve as recommendations or best practices rather than formal requirements. Notifications are specific messages or alerts that may be sent out but do not encompass the broader context of information sharing systems.
