Innovation ecosystems (IE) have increasingly gaining importance due to their potential to leverage regional development. In a previous research, authors have translated into processes how current IEs have been built or emerged. This process-based model can be used for building new or support the analysis of existing IEs. In order to evaluate the completeness of this model, this paper presents its mapping against the ARCON reference model considering that an IE can be seen as special type of Collaborative Network. Given the particularities of IEs, this paper also provides some elements of reflection that may be taken into account in future ARCON evolutions.
