Project communications are created as an output from the PMI process to manage communications and they are an input to the process to control communications. Some of the communication needs may be identified during plan schedule management.
Poor communications are a common cause of project delays and failures.
Project communications are necessary for multiple purposes. Some of those purposes are
- stakeholder engagement
- requirement clarification
- schedule and other progress reports
- deliverable status
- risk identification and management
- costs incurred
Factors to consider are the audience, push vs pull, technology, level of detail, format, formality, confidentiality, frequency, and timing. The organizational process assets may provide some guidance with templates and the organization's standards.
