The Four Metrics That Matter Most
First Contact Resolution (FCR) — The percentage of customer issues resolved in a single interaction without follow-up or escalation. FCR has one of the strongest documented links to customer satisfaction and retention, and correlates directly with cost: repeat contacts are expensive.
Customer Effort Score (CES) — A survey-based measure of how easy the customer found it to resolve their issue. Research has established CES as a stronger predictor of loyalty in service contexts than either NPS or CSAT.
Agent attrition — Annualized percentage of agents leaving. High attrition indicates operational dysfunction that precedes every other performance problem: training costs rise, tenure drops, FCR falls, customer effort climbs.
Cost per contact — Fully loaded cost (labor, technology, facilities, overhead) divided by contact volume. Useful as a benchmark for investment decisions, not as a primary optimization target.
Why Average Handle Time Is Overused
Average Handle Time (AHT) — the average duration of an interaction including talk time, hold time, and after-call work — is the most commonly tracked contact center metric and also the most commonly misused.
As a capacity planning input, AHT is essential. WFM cannot function without it.
As a primary performance metric for agents, AHT is harmful. When agents are measured primarily on AHT:
- Interactions are cut short to meet targets, reducing FCR.
- After-call notes are skimped, reducing data quality and AI effectiveness.
- Complex issues get escalated or transferred to avoid time penalties, increasing customer effort.
AHT belongs in capacity planning. It does not belong on the scorecard as a headline agent metric.
Metrics Worth Tracking But Not Leading With
- Service level — Percentage of interactions answered within a target time. Useful for staffing accountability; does not measure quality of outcome.
- Abandonment rate — Percentage of customers who disconnect before reaching an agent. A signal for capacity problems, not a target in itself.
- NPS — A relationship metric, not a transactional one. Useful at the account level; less useful at the individual interaction level where CES is stronger.
- CSAT — Interaction-level satisfaction. Widely used, moderately predictive, vulnerable to self-selection bias in response rates.
- Quality scores — Valuable when criteria are objective and linked to outcomes; misleading when they measure adherence to script rather than resolution of issue.
A Modern Contact Center Scorecard
A defensible modern scorecard covers four layers:
- Customer outcome — FCR, CES, CSAT.
- Operational efficiency — Cost per contact, service level, self-service containment rate.
- Agent health — Attrition, engagement, tenure distribution.
- Financial contribution — Retention rate, upsell conversion (for blended operations), cost avoidance from self-service.
The specific targets depend on industry, channel mix, and customer expectations. What matters is covering all four layers rather than optimizing one at the expense of the others.
Frequently Asked Questions
What is a good FCR rate?
Industry benchmarks vary by sector, but FCR in the 70–75% range is commonly cited for well-performing operations. Benchmarks are less useful than trend direction within a single operation.
How do you measure Customer Effort Score?
A post-interaction survey asking the customer to agree or disagree with a statement such as 'The company made it easy to handle my issue,' typically on a 5- or 7-point scale.
How often should metrics be reviewed?
Real-time metrics (service level, queue state) are monitored continuously. Operational metrics (FCR, AHT, adherence) reviewed daily. Outcome metrics (CES, CSAT, attrition) monthly. Scorecard composition reviewed annually.
