What if a ticket failed QA-testing:
In the past, we always created a new ticket (linked with the original ticket) because it was easier to follow up and quickly see what needed to be done (fi. fix a specifiek button).
But now we are trying to figure out the total actual costs of our new features and it is more easier when all work time is logged in 1 single ticket. (sub-tickets can be used to track issues)
What do most organizations do? Create a new ticket or reopen the original ticket?
