Monitoring and evaluating implemented his

As early as 1973, Richard Nolan described a concept of stages in monitoring computer applications. By 1979 he refined his stages because of the experiences many companies in business had with computer proliferation. The stages that Nolan described may be applied to Hospital Information System dynamics. He described a time when an institution may undergo a transition from computer management to data resource management. It is a stage in the process of computer applications that evaluates the proposed change, considers the users new sophistication with the system, and alerts administrative personnel about the impact of proposed changes. This paper presents an organizational concept for monitoring 20 elements when considering HIS changes so that unilateral changes that are uncoordinated can be avoided. When a hospital reaches a stage where changes in the system, both negative and positive can be monitored and evaluated, the organization is entering a stage of maturity.
