Our organisation is in it's early days of leveraging ArcGIS Enterprise and we're currently running with a quite simple approach of one user group per app. This works quite well at the moment as we have thematic apps where we may have something like Field Maps collecting data and a web map/dashboard for data access and visualisation. e.g. a "water infra" group for collecting data on fire hydrants. I do fear this approach will become unmanageable at some point and/or we'll reactively deploy new groups to suit particular use cases and create ourselves some issues that we'll have to unwind.
What we can (initially) see that we'll need is some broader groups that have access to larger thematic chunks of data (e.g. "asset management" for fire hydrants, bus stops etc...), but at this stage we've unsure of what else to consider when designing groups.
ArcGIS Sites is something we're thinking of implementing in the future, yet I don't feel our current group strategy is mature enough, plus we don't have a proper content tagging strategy.
Is anyone able to point out any resources on "things to consider" or any frameworks to help us with our group planning? I've looked through the ArcGIS resources without any luck yet
