For decades, leaders considering business process reengineering have been warned that 70 percent of initiatives fail. That figure, widely cited across boardrooms and management texts, was never backed by rigorous empirical data. Michael Hammer and James Champy explicitly acknowledged in 1993 that their 50 to 70 percent range was an unscientific estimate. By 1995, Hammer clarified that reengineering carries no inherent failure rate.

Business process reengineering targets the fundamental redesign of core workflows to achieve step-change performance improvements rather than small, incremental gains. While the mythic 70 percent failure rate is unfounded, the work remains demanding. Actual measured transformation success rates run near 31 percent. This reality changes the conversation from avoiding an inevitable disaster to managing a complex, high-stakes operational project.

Treating process overhaul with clarity requires separating received wisdom from documented outcomes. To explore the data and evaluate how to structure these initiatives effectively, read the full piece at https://bit.ly/business-process-reengineering-type
