Today I went to a meeting where one faction of a project wanted another faction of the project to modify their work habits so that the first faction wouldn't have to go crazy or, you know, read minds.
The project manager offered to have a sort of summit meeting between the two groups and draft an agreement. This is the standard solution in my organization. You draft an agreement. Nothing changes, but at least wronged parties have a piece of paper they can wave dramatically when they're whinging about how wretched their lives are.
In this case, the wronged party said she frankly couldn't stand seeing another meeting for this project on her calendar.
The project manager suggested that maybe they could meet to talk about the excessive meetings.
