Contemporary organizations increasingly transition to a service-orientation to better cater to the needs of customers. To offer the resulting complex service solutions, organizations collaborate in business networks to exchange services, which are typically conceptualized by means of service-dominant business models. As business models influence organizational performance, novel service-dominant business models should be evaluated with respect to how value in terms of costs and benefits is captured per actor. However, limited support is present in literature to guide the concretization of costs and benefits in networked, service-dominant settings to assess the viability of the model. In response, we propose a method to guide the concretization of costs and benefits in service-dominant business models. Building upon existing work in terms of networked value capture, we introduce design parameters to concretize costs and benefits and consequently guide the concretization of these parameters by means of a structured process.
