What does the communication management approach define? 1. How versions of products will be described on information sent to interested parties 2. How information should be sent to interested parties 3. How often information should be sent to interested parties 4. How the PRINCE2 roles will be combined during the project

The communication management approach is a plan that defines the method and frequency of communication with parties both internal and external to the project. It answers questions about what information needs to be communicated, to whom, how (the method of communication), and how often. Therefore, it explicitly defines how and how often information should be sent to interested parties (stakeholders). This ensures that communications are planned and controlled, rather than being ad-hoc.

1. How versions of products will be described is part of the change and configuration management approach, which deals with product identification and version control.
4. How PRINCE2 roles will be combined is an aspect of tailoring the project management team structure, which is documented in the project initiation documentation (PID).
