Here, we propose a methodology to determine value adding functionalities for convergent products. A collection of
base functions and sub-functions configure the nodes of a web-based (digital) network representing functionalities.
Each arc in the network is to be assigned as the link between two nodes. The aim is to find an optimal tree of
functionalities in the network adding value to the product in the web environment. First, a purification process is
performed in the product network to assign the links among bases and sub-functions. Then, numerical values as
benefits and costs are determined for arcs and nodes, respectively, using a mathematical approach. Finally, the
Steiner tree methodology is adapted to a multi-objective model for the network to find the optimal tree determining
the value adding sub-functions to bases in a convergent product.
