Create a button for generate State diagram (like UML) based on statuses and their transitions in SDM. It might look like CMDB visualizer without functions. Only one image with names of statuses and their transitions.
It can be separate for tenants and then for request, incident, ... .
Button location might be Service Desk > Requests/Incidents/Problems > Request Transitions > Visualizer (for requests)
It can display default transition, must comment and other attributes too.
I think, that i can create similar image at IT PAM, but not everybody has IT PAM installed.
