Olena Gapak

A balanced portfolio of metrics gives you a comprehensive understanding of what is happening and what needs to be improved. With the right approach to tracking and analytics, the Customer support department becomes the growth engine, moving the entire organization toward customer loyalty.

Team Performance and Efficiency

First response time

The number of minutes, hours, or days passed from when a customer submits a ticket to when customer support responds.


Your customers need to know that someone is dealing with their problem, even if it takes time to solve it. Remember that customers expect different response times depending on the channel through which they contact your Customer Support. For example, the expected response time for social media is much shorter than the expected response time for emails.

Average response time

Total time taken to respond during the selected time period divided by the number of responses in the selected time period.

Waiting for too long significantly reduces the level of customer satisfaction, even if the problem is eventually solved. It is crucial to analyze the Average response for each category, feature, or support rep to identify what causes the delays.

First contact resolution rate (FCR)

The percentage of incoming service calls or requests that are resolved during the first interaction with the customer.

This metric is seriously affected by the relevance and completeness of the internal knowledge base and effective ticket routing.

Average resolution time (ART)

Total time taken to resolve tickets during the selected time period divided by the number of tickets resolved in the chosen time period.

ART shows the average time taken to resolve an issue. To have more visibility into support workload, try measuring ART split by channel, tag, or rep.

Assignee stations

An average number of reps a ticket has been assigned to.This metric shows inefficiencies in the ticket routing mechanism. 72% of customers say that explaining their problems to multiple people is poor customer service.

Issue escalation rate

The percentage of support tickets that have been escalated to a higher support tier.

Number of interactions per ticket

The total number of interactions divided by the number of support tickets.

The higher this metric, the more likely the support process needs to be optimized and improved. If the response time is too long, the number of interactions may increase because customers ask for status updates.

Tickets unresolved

The number of unresolved tickets over a specific period.

Number of reopened tickets

The number of tickets reopened over a specific period.

Self-service usage

For online customer communities, track total users, number of active users, number of users that perform specific actions (e.g., posts per month). For a knowledge base, track pageviews and what people are searching for. For chatbots, track the questions people ask by category and the percentage of people who speak to the customer support rep after interacting with a chatbot.

The helpfulness of knowledge-base articles

The ratio of Yes/No answers for "Was it helpful?" questions at the end of a knowledge-base article.

Most often measured by a short survey at the bottom of the KB page. You can also count the number of customers who still want to contact the support team, even after reading an article from the knowledge base.

Internal Quality Score (IQS)

This metrics rates the conversations from the support team’s perspective.

IQS shows you if your support reps follow their training and if their answers are aligned with internal quality standards.

Top-performing reps

Knowing top-performing reps helps you with knowledge-sharing and mentoring programs. Identify top performers via following metrics:

  • High first contact resolution rate
  • High CSAT
  • High volume of tickets resolved
  • Low escalation rates


Employee Satisfaction Score (ESAT)

Employee Satisfaction Score (ESAT) is generally measured via a survey. The survey includes a numeric question on the 1 to 5 scale and open-ended questions about what could be improved in your team.

By researching employee satisfaction, you can prevent crises, retain talented employees, and implement effective bonus and motivation programs. The key to measuring this metric is the anonymity of a survey.

Employee Turnover Rate (ETR)

The total number of leavers in a month divided by your average number of employees in a month) x 100. The result is your monthly employee turnover rate as a percentage.

The problem of employee turnover increases Customer Support costs as you spend resources on recruiting, onboarding, and training. What causes a high ETR and how to control it is a complex topic. But measuring it is vital to create a motivated and competent Customer Support team.

Volume and Trends

Ticket volume

Average issue count (daily/weekly/monthly).

Ticket volume by topic

Average issue count by topic or category.

Ticket volume by type

Average issue count by type (feature request, technical issue, sales question, etc.)

Ticket volume by channel

Average issue count by support channel.

Ticket volume per customer

Total number of tickets divided by a total number of customers.

This metric helps you to understand if you are getting more requests because of new issues and bugs in the product or just because you are getting more customers.

Backlog volume

Tickets still reopened over a specific period (24h, 72h, one week, etc.)

Backlog outflow and inflow

The number of tickets received vs. the number of tickets resolved and closed (daily/weekly/monthly).

This metric shows you whether the backlog is shrinking or increasing.

Customer Satisfaction

Customer Satisfaction Score (CSAT)

A score measured through customer feedback gathered via one or more variations of the question: “How would you rate your overall satisfaction with the goods/service you received?”

Net Promoter Score (NPS)

NPS is measured with a single-question survey and reported with a number from 0-100. Customers categorize as promoters (score of 9 or 10), passive (score of 8 or 9), and detractors (score of 0-6).

Customer Frustration Score
