Abandonment Rate (Abandon Rate)

Abandonment rate measures the percentage of customers who disconnect before reaching a human agent. This is calculated by dividing the total number of incoming calls by the number of abandoned calls.

As a general rule of thumb, you should aim for an abandonment rate under 5%.

For contact centers, this rate is a critical indicator of friction in the customer journey, often tied to long wait times or poor routing.

Learn more about why abandonment rate matters.

 

Adaptive Routing

Adaptive routing is the use of data and AI to direct incoming customer calls and queries to the most appropriate agent, based on factors like:

-    Experience
-    Skill set
-    Availability
-    Customer history
-    Intent

In call centers, adaptive routing improves first-contact resolution, reduces transfers, and lowers wait time by matching customers with agents who are best equipped to help.

 

After-Call Work (ACW)

After-Call Work (ACW) includes the tasks an agent completes once an interaction ends, such as updating records, escalating issues, tagging tickets, or writing summaries. In contact center operations, ACW directly impacts handle time, agent workload, and data quality, making it a key area for efficiency and QA optimization. 

Here’s how to improve ACW.

 

Agent Burnout

Agent burnout describes the emotional and physical exhaustion contact center agents experience from high query volumes, challenging interactions, repetitive tasks, and performance pressure.

For CX teams, burnout often shows up as declining quality scores, reduced efficiency, and lower CSAT, signaling the need for better support and coaching strategies.

Here’s how to curb contact center agent burnout.

 

Agent Coaching

Agent coaching is the ongoing process of reviewing contact center agent performance and providing targeted feedback to improve skills, knowledge, confidence, and consistency. 

Learn about the skills contact center agents need and how to coach them.

 

Agent Desktop

An agent desktop is the unified interface agents use to manage calls, messages, and customer information in one place. In contact centers, it typically brings together CRM data, product information, scripts, knowledge bases, and QA tools.

A well-designed agent desktop should reduce context switching, shorten handle time, and lower cognitive load, enabling agents to focus on the customer rather than navigating multiple systems.

 

Agent Engagement

Agent engagement demonstrates how motivated, connected, and invested agents feel in their work. In contact center environments, high engagement is linked to better performance, lower attrition, and stronger CX, while lower engagement can lead to agent burnout.

Engagement can be tracked through surveys, participation in coaching, and retention metrics.

Here’s how to maintain agent engagement in a contact center.

 

Agent Experience (AX)

Agent Experience (AX) describes the day-to-day of a contact center agent, including their tools, processes, and environment. AX directly influences performance, engagement, and retention, as a positive agent experience with clear workflows, intuitive systems, and supportive feedback enables agents to serve customers more effectively.

 

Agent Performance Management

Agent performance management is a system of metrics, evaluations, feedback, and goals that are used to inform agent improvement. In quality assurance, it connects scores, KPIs, and coaching into a continuous loop, ensuring agents understand expectations and business goals, and are provided with clear pathways to grow.

 

Agent Utilization

Agent utilization is a metric that measures how much of an agent’s available time is spent actively handling customer interactions or other productive tasks. In contact center operations, this metric helps leaders and decision makers balance efficiency with sustainability.

Agent utilization is calculated by dividing the agent’s total handle time + after-call work by total logged-in time, and multiplying by 100. 

Low agent utilization rates? Here’s how to improve productivity
