They are usually responsible for planning, generating, and running regular project team meetings. So they get people together but sometimes have done no work since the last meeting they held, so when someone has a reasonable issue that doesn't meet with the pre done schedule 5 years ago when the project was first instigated, they have super Pikachu face and get mad at the actual doers because they don't get to just report "on schedule" to their bosses. They could be called the landlords ofthe project based on the sentiment of the greater Lemmy community.
