But fixing a bug requires time from your side (mainly doing the investigation) and from others (code reviews). So if the whole team is working on an “important” epic (this is, one with a deadline, like any other epic) and you come out of the blue with a bugfix unrelated to the epic without telling anyone: well, that’s weird isn’t it? Your EM/PM will ask you why you didn’t prioritise the epic’s tasks, and your colleagues could say that they cannot switch their focus or gather time for reviewing your fix (more so that it’s something that the EM/PM hasn’t approved).
So unless you are overworking (e.g., you work in your jira tasks AND on top of that you fix bugs) I don’t see it.
I would love to work on things that make sense like stabilising the system and all, but I work on whatever sells or whatever the EM/PM wants. These days unfortunately, shipping >>> fixing.
