Contact centre AHT reduction

Q: What is the fastest way to reduce AHT in a contact centre?

The fastest sustainable AHT reductions come from: (1) hold time reduction — reviewing the reasons agents place customers on hold and eliminating unnecessary holds through knowledge base improvement, system access improvement, or live chat support with a supervisor; (2) ACW reduction — auditing wrap code completion time and finding which agents spend disproportionate time in after-call work, then coaching them on efficient ACW completion; (3) navigation and system efficiency — if agents are spending 60–90 seconds per call navigating between systems or waiting for screens to load, screen-pop technology or system integration is the fix. These three areas typically account for 40–60% of the AHT gap between a centre's current performance and its benchmark. The fastest unsustainable AHT reduction is coaching agents to rush — this produces short-term AHT improvement followed by FCR decline and CSAT decline within 4–8 weeks.

AHT reduction without FCR analysis is one of the most expensive mistakes in contact centre management. Cutting handle time by rushing resolution costs more in repeat contacts and CSAT damage than it saves in productivity. The target is waste — not resolution time.

The fundamental rule of AHT reduction

Safe to target

→Hold time above the minimum needed for system transactions
→ACW time beyond what accurate documentation requires
→Repeated verification steps already completed by the IVR
→Extended scripted preambles before the customer is able to state their reason for calling
→System navigation time caused by poor screen design or lack of integration

Dangerous to target — protect

✗Time spent explaining the resolution clearly
✗Time spent confirming the customer understands and is satisfied
✗Required regulatory disclosures
✗Empathy moments — the validation, acknowledgement, and reassurance the customer needs
✗Complex troubleshooting required to reach the correct resolution

Before starting any AHT reduction programme, run the FCR-AHT correlation on your own data: do higher-AHT contacts have higher FCR? If yes, AHT reduction will cost FCR. If not, AHT contains reducible inefficiency.

AHT components and reduction levers

Hold time

12–20% of total AHT

Legitimate causes

Checking information not immediately accessible; consulting a supervisor; processing a system transaction

Waste causes

Checking information that should be in the knowledge base; waiting for a slow system; transferring rather than resolving

Reduction lever

Knowledge base improvement; system speed/integration; supervisor live chat support; permission to proceed without hold

Target?

Legitimate — reduce to the minimum needed for genuine system transactions. Hold time above 60s/call on simple contacts is a knowledge or system issue, not a resolution requirement.

After-call work (ACW / wrap time)

8–15% of total AHT

Legitimate causes

Accurate case notes; completing a system transaction; sending a follow-up email committed on the call

Waste causes

Extensive note-taking that duplicates what the CRM already captured; navigating away from the customer record after the call; selecting a wrap code slowly

Reduction lever

Template notes with merge fields; automatic case creation; streamlined wrap code list; ACW time coaching

Target?

Target 30–60s ACW for simple contacts; 60–90s for complex. ACW above 2 minutes on simple contacts is a training or system issue.

Talk time — resolution

60–70% of total AHT (the majority)

Legitimate causes

Explaining the resolution clearly; confirming the customer understands; completing required regulatory disclosures; empathy moments

Waste causes

Not identifiable as waste — this is the time the customer needs

Reduction lever

Not a primary target. Cutting resolution talk time cuts CSAT and FCR. Focus AHT reduction elsewhere.

Target?

Protect. Cutting resolution talk time is the most common and most damaging AHT reduction mistake.

Talk time — inefficiency

Variable — typically 5–15% of talk time

Legitimate causes

N/A

Waste causes

Repeating verification already completed by the IVR; re-reading back information the customer already confirmed; extended scripted preambles; off-topic conversation unrelated to the resolution

Reduction lever

IVR integration to pass verified customer data to the agent; script review to remove redundant steps; coaching on efficient information gathering

Target?

Legitimate target — but requires call-level analysis to identify which talk time elements are inefficiency vs. resolution.

Hold time reduction: the fastest win

In most contact centres, hold time is the fastest area to address because it has clearly identifiable root causes that can be fixed at source. Hold time above 45 seconds per call on simple contacts is almost always a knowledge base, system access, or authority issue.

Cause

Agent needs to check information not in the knowledge base

Fix

Add the information to the knowledge base. Identify which contacts generate most holds and build the KB content specifically to eliminate those holds. Track hold rate by contact type and KB article.

Cause

Agent needs supervisor approval before proceeding

Fix

Review the authority levels for the most common hold reasons. If 80% of supervisor approvals are routine (standard goodwill amount, standard exception), empower the agent to make that decision without hold. Reserve supervisor approval for genuinely high-risk decisions.

Cause

System is slow — agent waits for a screen to load while customer holds

Fix

System performance issue — escalate to IT with evidence: average hold time by transaction type, correlated with system response time logs. In the short term, consider whether the agent can continue the conversation while the system loads.

Cause

Agent is unsure how to complete the transaction and stalls with a hold

Fix

Knowledge gap — targeted coaching and training on the specific transaction. Consider whether a live chat channel to a supervisor (rather than a full hold-and-transfer) allows the agent to get guidance while remaining on the call.

Measuring AHT reduction safely

AHT by component

If total AHT reduces but hold time reduction is causing it, the programme is working. If talk time reduction is causing it, investigate whether FCR has changed.

FCR rate before and after intervention

The primary safety check — any AHT reduction that coincides with FCR decline is costing more in repeat contacts than it saves in handle time.

Hold rate per contact type

Measures whether hold time reduction interventions are working at the contact-type level. Allows the programme to be targeted rather than blanket.

ACW time by agent

Identifies which agents have high ACW relative to peers handling the same contact types — enabling targeted coaching rather than blanket pressure.

CSAT score before and after intervention

A falling CSAT during an AHT reduction programme is a warning signal that resolution quality or empathy is being cut along with the inefficiency.

WAPE on the new AHT assumption

Once AHT has reduced, the WFM model should be updated. If AHT assumptions are not updated, the staffing calculation overpredicts resource requirement and produces overstaffing.

AHT reduction questions

What is the fastest way to reduce AHT in a contact centre?

The fastest sustainable AHT reductions come from three areas: (1) hold time reduction — identify the most common hold reasons and eliminate the underlying cause (knowledge gap, system access, authority level). A 30-second reduction in hold time across all contacts is typically equivalent to 0.5 FTE saved; (2) ACW reduction — audit wrap code completion time by agent, identify outliers, and coach efficiently. Target 30–60s ACW for simple contacts; (3) system efficiency — if agents spend 60–90 seconds per call navigating or waiting for screens, screen-pop or system integration delivers immediate AHT benefit. The fastest unsustainable AHT reduction is coaching agents to rush — this produces short-term AHT improvement followed by FCR and CSAT decline within 4–8 weeks, at higher total cost.
