I think it's more marketing and profiteering based on correlation over causation. Almost every process these days is bought in by a new managerial hire, or after attending an event, where a talk or book that shows X companies that are very successful all followed the Y practice, and so 'we should too' as it's obviously the path to success. Rarely is there reflection on whether the process is working, and blame is laid at the feet of the workers. Despite many recollections and experiences retold about how processes may not work, they are silenced by the advocates of such processes who will show how successful they were (and also just happen to make their living by advocating rather than actually being on the ground).
