In my understanding there are two kinds of bugs:
- Bugs that are identified before an acceptance by the client
- Bugs that are identified afterwards
In JIRA I think it is necessary to associate bug type 1 with an Epic as they are a condition for completing the Epic.
But how do you treat bug type 2? As far as I understand it the epic should already be closed (see my related question). Do you associate no epic at all? Do you use a "bugs" epic? Anything else?
