Across the literature, is often claimed that the shortage of models to support projects in the collaborative dimension, creates distrust and pushes way organizations from those collaborative initiatives, such as the open innovation (OI). In the present work, a model based on three different scientific fields (Risk Management, Open Innovation, and Social Network Analysis), is introduces, aiming to support the management of OI projects. The model identifies project critical success factors (CSFs) by analysing three distinct collaborative dimensions (3-CD) that usually take place in OI projects - (1) Participation Degree, (2) Communication Degree, and (3) Response Agility Degree – of accomplished projects. Such CSFs can then be used to guide and estimate an outcome likelihood of upcoming or ongoing OI projects.
