The commercialization of new inventions requires a feasible and viable business model. But, how do

we evaluate its potential performance, especially as more often the innovation requires collaboration

between several firms? The objective of this paper is to demonstrate a framework for estimating

performance in a networked business models. Our research method is action research. The empirical

data comes from a case of business model creation for “physical activity prescription” by network of

four companies in Health and Wellbeing sector. By combining existing approaches for business

modeling and business networks with our empirical data, we describe the focal points of

performance estimation in the context of business network. The results highlights the importance of

measuring all main components of the business model and also the business network partners’ view

on trust, contracts and fairness.
