Most organizations view customer complaints as nuisances to be quickly resolved. However, the Vaud University Hospital (CHUV) in Switzerland has shown that complaints can be invaluable sources of innovation and insight into systemic issues. Over a decade, CHUV has used customer feedback not only to address individual grievances but to uncover deeper problems and instigate broad improvements. An example includes fixing a surgical scheduling error that caused patient anxiety. Through a cross-industry training initiative with the EHL Hospitality Business School, CHUV equips healthcare professionals with service skills from hospitality to enhance patient experience and trust. Simple changes, such as personalized communication on test results and reframing teamwork to reduce staff burnout, are fostering significant improvements in care quality and employee morale. The hospital’s approach highlights three practical steps: treat complaints as assets, redesign processes with customers, and borrow service excellence techniques from other industries. This paradigm shift turns customer frustrations into blueprints for systemic innovation and better service.
