Service level agreement

Response time is how long a customer waits for a reply once they have made contact. Teams report it as a first-response figure and as an average across subsequent replies, because a fast opening reply followed by long silences produces a poor experience despite good headline numbers.

Full resolution time is the total elapsed time from a customer’s first message to a confirmed resolution, including waiting, escalation, and overnight gaps. Unlike response time, it reflects the experience of waiting for an answer rather than the speed of the first reply alone.

Backlog is the set of unresolved tickets carried past their target response window. A growing backlog signals that arrival rate has outpaced capacity, and because ageing tickets attract follow-up contacts, backlog tends to generate additional volume rather than simply waiting quietly to be cleared later.

Business rules are the conditions that decide how a contact is prioritised, routed, or escalated. Typical rules combine customer tier, channel, detected intent, and elapsed time to determine where a conversation goes and how quickly it must be answered under the applicable service level agreement.
