An organisational model in open innovation is proposed for the Colombian Air Force that could be implemented in the institution or in other military entities, as well as in companies with hierarchical structure. It includes a new perspective of the articulation of the university, enterprise, and state with the theoretical foundations of open innovation. The main objective of this research was to design an open innovation (OI) model to articulate the actors of the Science, Technology, and Innovation System (ST&I) of the COLAF, throughout a qualitative approach of documentary review, where variables of open innovation, internal, and the external factors of open innovation were defined for the subsequent construction and proposal of the model. Concluding, the construction of this OI model for the COLAF could allow an inclusive and binding model of Colombian society with university, enterprise, and state to join efforts and to cooperate for achieving an stable innovation ecosystem.
