Contact queue
A contact queue is the set of client calls, chats and messages that have arrived but not yet been picked up by an agent.
What it is
Requests rarely arrive evenly. At peak hours more clients write or call than people can handle at once, and the rest wait. That waiting line is the queue. In voice it is visible: the client hears music. In messengers it is often invisible: the message simply sits unread while the client assumes nobody cares.
How it looks in numbers
The main measures are the number of contacts waiting right now, the longest current wait, the average wait time and the abandon rate, meaning the share of clients who gave up before getting an answer.
An illustrative example: at 11:00 there are 40 unanswered chats and the oldest has waited 25 minutes. If the agreed target is an answer within 10 minutes, the line is already failing, even if the daily average looks fine.
Why it matters
The queue is where money leaks quietly. A client who waited too long writes to someone else, calls back angry or disappears. Its shape also tells a manager what to fix: a queue that grows at the same hours every day is a scheduling problem, a queue that grows after a mailing is a planning problem, a queue that never shrinks is a staffing problem.
The typical mistake
Not seeing the queue at all. When messages are spread across personal phones and separate chats, nobody knows how many clients are waiting and for how long. Another mistake is taking the newest messages first because they are easier. Agree on the order, usually oldest first with clear priorities, track the longest wait in real time, and review the hours where the queue regularly breaks the target.

New metrics appear that calls never had: concurrent conversations and promises kept. Measure them in working hours and together, never one at a time.
