The boundaries between products and services are vanishing and offers such as hybrid product service bundles, are becoming increasingly important. These solutions are referred to as Product Service Systems (PSS), which address individual customer needs as problem-oriented solutions. In order to enable the configuration of such systems as well as the possibility of planning and supporting services on the basis of a holistic model, a data model that contains both product and service information as well as their dependencies, is required. For this purpose, existing CAD models must be extended with further information. These are e.g. maintenance intervals of parts, costs of the parts, or also index numbers for the complexity of installation. This paper shows how to enrich a CAD model by integrating information into it and creating an interface with Excel. Thereby, the model can be used by different actors in the PSS for configuration and development, service planning and support of service technicians. Finally the approach for enriching a CAD model is implemented using the example of an engine test bench.
