The tyranny of AHT
Slides done? Here’s the same idea in a bit more depth — the part worth keeping.
In depth: the same number, two opposite uses
Average handle time is indispensable as a planning input — you literally can’t size staffing without it, because volume times AHT is the workload every staffing calculation rests on. As an agent performance target, the very same number becomes one of the most destructive metrics in the contact centre. Same figure, opposite consequences, and confusing the two roles is where the harm comes from.
Why it’s toxic as a target
Tell agents to lower AHT and the only levers they actually control are the harmful ones: rush the customer, skip the checks, avoid the notes, or transfer the call to stop their own clock. The call ends faster — and comes back tomorrow as a repeat. That’s the repeat-contact trap: a shorter handle time that fails to resolve the issue just shifts cost downstream, so cutting AHT while repeat contacts rise isn’t a saving at all, it’s the same work done twice with an unhappy customer in between. The metric improves while the operation gets worse — Goodhart’s law in its purest form.
Target the outcome, keep AHT as a diagnostic
The fix is to manage the outcome and observe the AHT: measure whether the issue was solved (first-contact resolution) and how it felt (quality, CSAT), and AHT lands where it naturally should for each contact type. This isn’t “ignore AHT entirely” — a specific agent sitting far above their peers may genuinely need coaching or system help, and that’s worth investigating kindly as a diagnostic. The difference is between a targeted, supportive look at an outlier and a blanket target that pressures everyone to rush every call.
The principle to remember: forecast AHT, don’t weaponise it. It’s a brilliant planning input and a terrible agent target — chase resolution and experience, use AHT as a diagnostic for outliers, and let the average sit where good service puts it.
Quick quiz
Five questions. Pick an answer to each, then check your score.
1. What’s the dual nature of AHT?
Same number, opposite consequences depending on how it’s used.
2. Why is AHT essential for planning?
You can’t size staffing without AHT — it’s a core planning input.
3. What happens when you set AHT as an agent target?
‘Get off the call’ is the wrong instruction — it optimises the wrong thing.
4. Why isn’t a lower AHT automatically a saving?
Cutting AHT while repeat contacts rise just shifts cost downstream.
5. What should you target instead of AHT?
Manage the outcome (resolution, CSAT); observe AHT as a diagnostic for outliers.
