We have a small team, so one of the first things I did was go in the opposite direction and reduce permissions across the board, making event defining less available to everyone, so we didn’t have a big mess. I let everyone know they could have more access if they needed it, but not one person has said they need more. They cannot edit the data set but they can run and publish reports. Everyone's okay with using what we already have, and that helps keep things manageable.
What approaches do others use to manage their events and properties?
