The first step is to create an initial list of all members who will be involved in your project. For example:
- Project manager
- Project team member 1 (assigned tasks)
- Project team member 2 (assigned tasks)

A communication matrix helps you create an effective plan for project communication. It identifies who needs to communicate what, when, and how to whom.
