When planning communications management, what input identifies key stakeholders?

Work performance information is an output of executing and monitoring processes, not an input used to identify stakeholders during planning.

The project schedule outlines task timelines and dependencies but does not identify who the key stakeholders are.

The project charter formally authorizes the project and lists high-level stakeholder information, including the project sponsor and those with authority or influence over the project. This makes it a primary input when planning how to communicate with stakeholders. Without it, the communications management plan would lack the foundational stakeholder identification needed to tailor messaging.

Work performance reports are compiled during monitoring and controlling and reflect project status, not stakeholder identification.
