is there something like a jira uml diagram? -

i'm new jira , abilities of customizing , setting project/role/group , on confusing me.

do know if there overview how acts together, uml diagram?

i'd suggest go admin workflow editor , have @ used in projects (or default workflow @ first) in graphical representation. there can @ transitions between status , check details.

you notice conditions, validators , post-functions, if want level of detail can check in standard workflow , see fields manipulated and/or checked.

this closest uml diagram think of.

other suggest create test project, create test issues , use company/department works. fall quickly, if people roles involved.
