Customer Effort Score

Customer Effort Score in Practice

Most organisations focus on making customers happy. CES research shows it is more important to make things easy. A customer who got their problem resolved without hassle is more loyal than one who had a surprisingly delightful experience. It is counterintuitive, but the data is unequivocal.

CES is typically deployed as a post-interaction survey with the question:

"[Company] made it easy for me to handle my issue." Scale: 1 (Strongly disagree), 7 (Strongly agree)

Or in a direct formulation:

"How easy was it to resolve your issue today?"

Calculation

CES is typically reported as an average score or as the proportion of customers who respond 5, 6, or 7 (high ease). There is no standardized calculation method as with NPS.

Why Low Effort Beats High Satisfaction

Research reveals an asymmetry: Delighting the customer beyond expectations rarely increases loyalty significantly. But disappointing the customer by creating unnecessary effort has a strong negative effect on loyalty and churn. The conclusion: Remove friction first, add wow experiences afterward.
