Over the course of the past three decades, facilities management has become the subject of an increasing number of research and development efforts. The main objective of the present research was to examine the efficiency of maintenance under alternative maintenance policies and different sources of human resources. The research focused on the maintenance of public hospital buildings in Israel, with the objective of providing a model for multi-system facilities operating in a dynamic environment. This paper describes the last three stages of the research: the establishment of key performance indicators, the implementation of these indicators in a case study in order to appraise them, and the validation of the indicators. Four key performance indicators were developed, as follows: the Building Performance Indicator (BPI), the Manpower Sources Diagram (MSD), the Maintenance Efficiency Indicator (MEI) and the Managerial Span of Control (MSC). This paper illustrates a case study in which the four developed indicators were implemented in practice. Characteristics of the case study hospital are presented and analysed. Finally, the conclusions and recommendations drawn from the analysis of the hospital case study are discussed, validated and deliberated upon. The approach presented in this paper integrates performance, financial, human resources and organizational aspects to facilitate an improved evaluation method of the parameters affecting the execution of maintenance activities.
