Postulates a framework for managing knowledge workers, defined as ‘technologists who bring learning to work that is at least partly manual, such as lab technicians’. The best chapters regard the enterprise’s use of info (foundation info, productivity, competence, resource allocation) in order to create value and manage assets, which Drucker describes as people themselves; and knowledge-worker productivity, which turns on creating a culture where individuals know how to make what they know useful to others. Always thoughtful and provocative if typically aimed at larger organizations.
