Various people are responsible for communications to different stakeholder groups, both internal and external to the organization. These delegations of authority are:

Organizational process assets are enterprise-wide assets owned by the broader organization, whereas communication authority delegations are specific to the portfolio level and therefore classified as portfolio process assets.

The portfolio performance plan is focused on measuring and tracking portfolio performance outcomes, not on assigning or documenting communication authority structures.

The portfolio communication management plan documents what communications occur, to whom, and how, but the delegations of authority themselves are categorized as portfolio process assets, not merely a subsection of the communications plan.

Portfolio process assets encompass the policies, procedures, templates, and governance structures that are specific to and generated by a portfolio, including delegations of authority for communications. These assets are retained and reused across portfolio management process cycles. Because the delegations are portfolio-specific governance artifacts rather than enterprise-wide organizational policies, they belong to portfolio process assets rather than organizational process assets.
