Is there a best practice that can be said for whether to add a tag and have users filter on it or just create a separate list?
We have many groups in our SharePoint application that all have many projects underneath them. We approached the problem by creating a tag for each project so they can have a master list of tasks / issues / documents that they can quickly switch between. But more and more users are asking to just create separate lists per project, effectively removing the need for the tag but increasing complexity as they now have to navigate to the different lists to see each project's items. Using separate lists feels like folders and loses the ease with which users can quickly change a view.
Is it a pipe dream to have users all use one list and tag things or should we just accept the bloat of having a list per project?
