Measuring effort without reducing service quality

An effort score asks how easy a customer found an interaction.

Customer Effort Score (CES) records how easy a customer found an interaction; it does not show whether the outcome was correct. Pair CES with resolution, repeat contact and correctness checks so an easier experience counts as progress only when the issue is resolved properly.

Ask at the right moment

Define the task first, such as a delivery query, account change or complaint resolution. Ask “How easy was it to resolve your issue?” after the customer has had a chance to see the outcome, using a scale from 1 (very difficult) to 7 (very easy).

Use the same question and scale for the same task over time. Calculate the average by adding the ratings and dividing by the number of responses; a higher average means customers found the interaction easier. Report response volume with the score, and break results down by task, channel and case type rather than averaging a complex complaint with a simple password reset.

Pair CES with first contact resolution ratio, repeat contact rate and checks for reopened cases, corrections, correct outcomes and policy compliance. These measures show whether the issue was resolved on the first contact, whether the customer had to contact you again, and whether the answer was accurate and appropriate.

Customers who abandon before completion may never receive a survey. Sample those exits separately where possible.

Key Metrics for Measuring Customer Effort and Service Quality

First Contact Resolution Ratio
Measure of successful resolution on initial interaction
Repeat Contact Rate
Percentage of customers needing follow-up
Case Reopenings
Number of cases reopened after closure

How to Measure Customer Effort Correctly

  1. Define the taske.g., delivery query, account change, complaint resolution
  2. Use consistent question and scaleEnsure comparability over time
  3. Pair with resolution metricsCheck first contact resolution, correctness, policy compliance
  4. Analyse by task, channel and case typeAvoid averaging simple and complex interactions

Prevent metric gaming

Do not reward teams for closing a case quickly if the customer must reopen it, and do not move difficult cases out of the measured queue. Review a sample of low-effort and high-effort cases to understand the causes, including cases where a slower, careful response was appropriate.

Report CES and service outcomes by task and customer segment, alongside response volume. If CES improves while first contact resolution falls or repeat contacts, reopenings or corrections increase, the easier experience may be coming at the expense of resolution or correctness.

When the score changes, look for a corresponding change in repeated steps, repeat contact and correctness. If ease improves while error rates rise, the redesign is not finished.

Impact of Improving CES Without Resolving Issues

Improved CES
Easier experience reported by customers
Declining First Contact Resolution
More issues unresolved on first contact
Rising Repeat Contacts
Customers contacting support again
Increased Corrections/Reopenings
Incorrect answers or incomplete resolutions
