Queues Reveal Capacity
What is a growing backlog actually telling you?
The idea
A growing queue means arrivals exceed the rate of service, and no amount of urgency changes the arithmetic.
In the real world
A support backlog grows every week while the team works longer hours.
Going deeper
A growing queue is arithmetic, not motivation: arrivals exceed service rate, and the gap is accumulating. Effort has a ceiling well below what closing a persistent gap requires.
Only three things change it — fewer arrivals, faster service per item, or more capacity — and exhortation addresses none of them while reducing the third through burnout. The useful measurement is arrivals per week against completions per week, which turns an argument about how hard people are working into a number that points at one of the three levers.
Where it stops applying
Short-term surges genuinely can be absorbed by extra effort, and treating every backlog as structural misses the ones that are temporary. The distinction is whether the gap persists across several periods.
Why it matters
It tells you that a backlog is a measurement, not a motivation problem.

Test yourself
A support queue grows by 30 tickets a week. The team is told to work harder and the queue keeps growing. Why?
