The key to increasing operating room efficiency is increasing productivity. Standardizing and streamlining of internal procedures reduce bottlenecks, and computers speed the flow of information so that continuous improvement of the system becomes possible. Patterns and themes can be discovered only when one sits back and listens and watches, shifting the focus from fixing problems to discovering patterns and the structures underlying them. Rethinking the system and evaluating all aspects of the care delivery cycle, abandoning the "sacred cows" of operating room practice, and creating a vision for health care in the future are essential to survival in the managed care environment.
