UdZ 3-2012

38 Unternehmen der Zukunft 3/2012 UdZ Dienstleistungsmanagement with simulation results from former solutions that are already on market. To have a very safe proposition of sustainability of the developed so- lution, reference data from other companies, the branch and eventually from the whole value chain will be necessary and have to be integrated in to the tool. Performance standards may deliver a common understanding of a sustainable solution. Future work for the research has several aspects. First of all, more qualitative social criteria de- scribed in SA8000 guideline need to be imple- mented into the model and connected with the other sustainability dimensions. The current approach helps to compare company’s own so- lutions among themselves by transparent data. A main challenge will be to work out usable, standardized data to be able to compare the results of the simulations with other companies. Especially the results from the MIPS factors or the environmental sustainability dimensions would then be more effective to support a change to a sustainable thinking. Furthermore, the most relevant information that can be easily selected and reported by companies has to be gathered and selected together with the industry partners in the project of SustainValue. We are also looking for other companies, beside the SustainValue industry partners, that are in- terested in testing and improving the life cycle costing tool. A wide range of industries and a great number of inputs can help improve the accuracy of the tool. Literature [1] Brenken, B., and G. Gudergan. Fakten und Trends im Service. Klinkenberg, 2010.
