Aligning modes of organization with technology: Critical transactions in the reform of infrastructures

International audienceThis paper is about the alignment of technology and modes of organization in infrastructures in the context of their reform. Since infrastructures are characterized by strong technical complementarities, we explore the resulting 'critical technical functions' that need to be performed in order to guarantee the expected technical performance of the system. We characterize 'critical transactions' as essential to provide adequate support to these functions. We distinguish various modes of organization that can effectively coordinate these critical transactions. We argue that the features of these transactions determine the alignment between organization and technology and should be taken explicitly into account when reforming infrastructures
