Does your team know the changes you are making to project plans? Often we think because we've discussed something (however long ago), then thought about it and come to a decision on our own, everyone will know our intentions. But they can't read our minds! We have to take that extra minute to communicate our decisions to those affected by them.
What decisions have you made today? Who will be affected by your decisions? How will you let them know? --call, email, IM, other?
