Research shows project managers spend 90% of their time communicating. Poor communication is a primary cause of project failure.
Communications formula:
Number of communication channels = n(n−1)/2
Where n = number of stakeholders
5 people: 10 channels; 10 people: 45 channels; 20 people: 190 channels
This is why large teams need communication plans, not ad hoc messaging
Communications Management Plan includes:
Who needs what information
When they need it
How it will be delivered (email, meeting, report)
Who is responsible for communicating it
Communication types:
Formal written — contracts, charters, project plans
Formal verbal — presentations, formal meetings
Informal written — emails, texts, instant messages
Informal verbal — conversations, hallway discussions
Push vs. Pull vs. Interactive:
Push — send to recipient (email, report) — no confirmation received
Pull — recipient retrieves (portal, wiki, shared drive)
Interactive — real-time exchange (meeting, phone call) — most effective for complex issues
