“The greatest problem in communication is the illusion that it has been accomplished” —variously attributed to Georges Bernard Shaw or Daniel W. Davenport (who knows?).
This is certainly an eternal truth and should hang as a reminder on all change managers desks and on the walls of all of those in charge of organizational transformation.
Communication needs to overflow, it is always too easy to convince oneself that it has been accomplished and stop communicating.
As a useful rule of thumb, repeat until people feed back that they have heard enough.
