> Queues are an inappropriate construct for managing work.

I disagree. A queue is used to assign priority to a project. When there is more work than people to do the work, you need to prioritize and triage. Just because there is a queue doesn't mean that you can't handle urgent work. You can move it to the head of a queue.

Usually what accompanies a queue is a ticketing system. Nobody like these, but when the organization reaches a certain size, you need this. Tickets are good because it forces the requesting party to put down in writing what they want. This is a necessary step to ensure that right work is done, and it leaves and audit trail, for future people to see what decisions were made and what work was done.

I've worked in an organization where we used a stack based method. In that case the most important thing was the last request. This isn't a good way to work, because it's hard/impossible to maintain focus.
