Although the potentials of data analyses appear promising, companies often fail to develop specific ideas und successfully implement complex data analyses. In this paper, we present BMC Data, a novel, stand-alone tool for the comprehensive assessment of the maturity of a company’s business model in terms of data integration. To obtain a holistic view of all facets of a business model, this analysis reflects on all relevant dimensions of data integration. We tested the functionality of BMC Data in a survey aimed at managing directors and persons at management level (sample size n = 158) within a wide range of company sizes and branches. The evaluation shows that BMC Data is suitable for supporting companies in analysing and reflecting on their business model.
