Successful introduction of major new systems into complex medical organizations requires an effective blend of good technical and organizational skills. The technically best system may be woefully inadequate if its implementation is resisted by people who have low psychological ownership in that system. On the other hand, people with high ownership can make a technically mediocre system function fairly well. Managing Technological Change focuses on the successful strategies for implementation of information systems within medical organizations as well as on effective management strategies for the altered organization once the new systems are in place.
