What makes some projects succeed while others fail? Michael Tushman and Ralph Katz explore this question in their groundbreaking study of gatekeepers in the R&D sector. Drawing on empirical data and cutting-edge theories, they demonstrate the key roles that gatekeepers play in determining the success or failure of projects, and offer practical advice for managers and leaders seeking to improve their project performance.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.This work is in the "public domain in the United States of America, and possibly other nations.
