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

Agreements

Explanation:

The National Incident Management System [NIMS] which aims at improving the nations response to emergencies have come up with a collection of methods and principles that would be used by the Non-governmental organisations, private sector and local, state and federal emergency managers.

NIMS designed a set of self-assessment for these groups that could be used to ascertain their communications and information management systems preparedness. The document contains a key information on agreement, and it was clearly stated that it must be executed between stakeholders to make sure that the items stated within plans and procedures must be in affect when an incident happens. It specifies all of the communications systems and platforms that parties will use to share information.
