My manager is insisting to have criteria to help us decide when a project (in the most simple meaning the word "project" can have) needs to be helped by the project manager and the project management tool (in our case Wrike).
I don't know if you use these kind of criteria and if you use some kind of decision tree for that. What I told my manager is that any project that are dealt with by more than one person and/or that is taking more than 1 month should be put in Wrike and needs help from me, but he wants something more formal I guess.
