Analysis of service platforms by a portfolio approach

This work provides a framework for techno-business analysis of service platforms that can be used for evaluation of business models and strategic positions in collaborative service provision. It is based on the following modeling tools: techno-business model, generic service platform approximate, scenario modeling techniques, and service and enabler portfolio analysis. Our modeling approach is a synthesis of qualitative and quantitative analyses. We show that Markowitz' portfolio theory (financial risk-return analysis) can also be applied on service and on enablers portfolios if their specificity is realistically modeled. We demonstrate the most important modeling procedures theoretically and evaluate them practically on a chosen service delivery platform. Our research results and experiences show that service portfolio theory is very useful for evaluation of business strategies of different industrial actors, participating in collaborative service provision.
