A good administrator needs to have excellent “domain knowledge” about his hospital, familiarity with a plethora of technical terms, and must constantly update her knowledge to keep pace with the rapidly changing new technologies. Modern tertiary care hospitals purchase & utilize extremely sophisticated and expensive equipment, which requires domain knowledge about the different super-specialties. They also need to employ Consultants with multiple degrees and years of experience and training. A hospital administrator needs to be familiar with the equipment, the different types of specialists and super-specialists, and the complex interactions between them.
