Reality check.
Complaint: tickets created by the QA team for developers, even seemingly trivial ones, stagnate in Jira for months and sometimes years without anyone looking.
Written plan: Hire somebody who will be actually responsible for planning and prioritization. Hire more developers, so that the existing ones are not overloaded.
Reality: "This is not a realistic plan. There is a budget, and you are not the one who makes hiring decisions, so shut up and stop creating tickets unless there is something really serious".
So - is the complainer above serious, or not?
(all of the above is pure fiction)
