This communication aims at laying the theoretical foundations for a convergence of heterogeneous actors who are all involved in a common mission throughout the potentialities of information systems. The general problem consists in understanding how inter organizational information system can contribute to the convergence of heterogeneous legal, procedural and institutional actors. We selected a particularly heterogeneous institutional ground where we led a longitudinal case study on the fight against the illegal work of departmental and national level. From the perspective of theoretical results, three innovative concepts have been highlighted: the information-energy, the organizational otherness and the digital otherness. From a management viewpoint, we advised some recommendations and a national action plan.
