IAB Polska/PwC01/2026Poland
A measure of the effort a customer had to exert to resolve an issue — 'how easy was it?' on a scale of 1–7.
Why it matters
Better than NPS at predicting whether a customer will stay: people leave because of friction, not lack of delight.
What's missing without it
Without CES, you can improve service politeness without noticing the real problem lies in the number of steps.
When it is used
After contact with support, after a complaint process, after registration.
How we use it
Question asked after contact with support or after self-resolving an issue.
