Agile communication is effective because:

A.
the use of charts and diagrams over written reports creates clear, targeted
communication, and customer involvement in monthly reviews eliminates changes in
requirements.

B.
daily iteration planning allows change to be managed, and weekly standup meetings
ensure that impediments are quickly identified and effectively managed or removed.

C.
release and iteration planning keep team members aligned, daily synchronization
eliminates confusion, and iteration demonstrations keep the team focused on deliverables.

D.
Agile communication methods focus on detailed, written requirements and specifications
that are more complete and allow the team to manage change more effectively.
