Three Berkeley-Haas leaders have made the 2015 Thinkers50 global ranking of management pioneers: Lecturer Steve Blank, (#20), Adj. Prof. Henry Chesbrough, (#24) and Affiliated Prof. Morten Hansen (#34). 
Blank, who is credited with launching the Lean Startup Movement, debuted on the list this year. Chesbrough has made the list four times for his work on Open Innovation.
Hansen, co-author of Great by Choice (with Jim Collins, 2011), is on the list for the third time.
The Thinkers50 global ranking of management thinkers is published every two years. Thinkers50 launched in 2011 and has been described by the Financial Times and others as the “Oscars of management thinking.”
