What is the theme in Jack: Straight from the Gut by Jack Welch?

Throughout the book, Jack reiterates, "bureaucracy strangles." It stifles creativity and innovation, which in turn, slows growth and production. Informality, Jack concludes, is liberating. Jack challenges GE's hierarchal philosophies over many years. He ruffles a lot of powerful feathers in the process. He risks not being promoted by holding his entrepreneurial and informal philosophies of how operations should effectively be run. Roy Johnson, head of GE's human resources, is a traditionalist and holds tightly onto bureaucratic procedures and routines, including candidate hiring and promotion lists and protocol.
