Original surveys, indexes and evidence reviews, each published with its method and data.
A 2025 Gartner survey finds 79 percent of employees have low trust in their organization's ability to change. Only 32 percent of leaders report healthy adoption of the last change they led.
The claim that 70 percent of change programs fail began in 1993 as a self-described unscientific estimate about reengineering. A peer-reviewed review found no reliable evidence for it, and the survey record points to better measures.
