hi JJ20,

it is indeed a good question who will do that administration (and maybe also how) from a data governance concept. eg is the Business Application IT Application Owner responsible for this (or another party)? At least it needs to be controlled. Are they responsible for the Application Service level as well?

Do we facilitate that by backend (roles) or do we facilitate that by specific catalog item(s) Manage my Business Service (no roles required). 

There is not 1 answer for all scenarios right. 
Do you have discovery?
Is the Business Application a DevOps application (then the ownership might be the full stack) or more traditionally supported (where stops the responsibility for the IT Application Owner)? 

BR,

Barry
