Construction of Productivity Models - A Tool-Supported Approach in the Area of Facility Management

Abstract

Productivity models specify input and output factors to inform productivity analyses. Current research and business practice face the challenge of developing a wide range of different productivity models. These models were created simultaneously but isolated from each other. As a consequence thereof, several practices of productivity model construction have emerged. This paper presents a unifying modelling language that lists and interrelates the essential constructs, pertinent to productivity models. Ultimately it was transferred into practice by employing a software tool. The application was conducted in the area of facility management, supporting two different approaches of productivity benchmarking. Facility management features a huge diversity of offered services and bundles. Thus, facility managers cope with various definitions of productivity that are then modelled with our approach.
