Quantitative Alignment of Enterprise Architectures with the Business Model

For many companies, information and communication technology (ICT) is an essential part of the value proposition. Netflix and Spotify would not have been possible without internet technology. Business model up-scaling often requires a different ICT architecture, because an up-scaled business model imposes different performance requirements. This new architecture needs investments and has different operational expenses than the old architecture and requires recalculation of the business model. Investment decisions, in turn are guided by performance requirements. There are currently no methods to align a quantified business value model of a company with performance requirements on the enterprise architecture. In this paper, we show how to derive performance requirements on an enterprise architecture (EA) specified in ArchiMate from a quantification of a business model specified in e(3)value. Second, we show how we can aggregate investments and expenses from an ArchiMate model and insert these into an e(3)value model.
