When are we “done”?

● My Manager told me to work on something else...● Code has been commited to the repo...● Code has been commited to the repo with tests...● Code has been commited to the repo with tests that work...● Those tests have passed...● QA have told me that those tests have passed...● I've closed the ticket...● The code is in production...

● Icinga/Nagios:– 0 is OK– 1 is Warning– 2 is Critical

● Jenkins:– 0 is OK– Anything else is a failure
