The purpose of this paper is to increase understanding about the use of embedded open source software in commercial telecommunication products. This paper applies concepts of value-creating systems to sourcing and use of open source software. In value creating systems, open source software communities do not operate in similar way as companies. Differences derive from organizational culture, values and motivation to create value, e.g. to develop the software. Companies are monetarily motivated to create value for their customers but open source software communities are mainly voluntarily creating value to themselves and their peers. These differences have to be understood and taken into account when companies are using open source software in commercial products. In this paper, a model proposal describing collaboration with the open source community when using open source software in commercial products is outlined. Key findings about applying the model in a case company are presented.
