The common belief that the vast majority of organizations adopting and integrating Scrum come from a Waterfall-like background was supported by the survey. 24% use Scrum for some projects while using
Waterfall for the rest. 13% use Scrum exclusively, while 31% indicate no use of Waterfall. 23% felt it was a difficult transition from a Waterfall-based method to Scrum. Another perception, stated by 25% of respondents, was that there were no clearly identified metrics to identify and measure the successful delivery of Scrum projects.
