Why Measurement Matters
Contact centres generate substantial volumes of data, but not all metrics are equally useful. Tracking too many KPIs can dilute focus and create confusion about priorities. Tracking the wrong ones can drive behaviours that harm customer experience. The challenge is identifying the metrics that genuinely reflect operational health and customer outcomes.
1. First Contact Resolution (FCR)
First contact resolution measures the percentage of customer interactions that are fully resolved during the initial contact, without the customer needing to call back. FCR is widely regarded as the single most important contact centre metric because it directly correlates with customer satisfaction, operational efficiency, and cost. A customer whose issue is resolved first time is significantly less likely to call again, reducing overall volume and cost. Target: 70-75% for general enquiry lines, higher for specialist teams.
2. Customer Satisfaction (CSAT)
CSAT captures the customer's perception of the interaction quality. It is typically measured through post-call surveys using a simple scale. While subjective, CSAT provides a direct signal of how customers experience your service. The key is ensuring sufficient response rates to make the data statistically meaningful: a CSAT score based on a 5% response rate tells you very little. Target: 4.0 or above on a 5-point scale.
3. Service Level
Service level measures the percentage of calls answered within a defined timeframe: typically expressed as "80/20" (80% of calls answered within 20 seconds). It is a measure of accessibility and directly affects customer experience. Consistently missing service level targets indicates insufficient staffing or poor workforce management. This metric should be monitored in real time to enable intraday adjustments.
4. Average Handle Time (AHT)
AHT measures the total time spent on a customer interaction, including talk time, hold time, and after-call work. It is an efficiency metric and a key driver of staffing requirements and cost. However, AHT should be managed carefully: aggressive AHT reduction targets can pressure agents to rush calls, harming quality and resolution rates. The goal is to identify and eliminate unnecessary handle time without compromising the customer experience.
5. Agent Attrition Rate
Agent attrition: the rate at which agents leave the organisation: is often overlooked as a KPI but has a direct and significant impact on quality, cost, and customer experience. High attrition drives up recruitment and training costs, reduces the average experience level of the team, and creates capacity gaps that affect service levels. Monitoring attrition rates and understanding the root causes is essential to building a stable, high-performing operation. Target: below 25% annually for the industry.
