This contribution offers the author’s personal experience with a project that took place 25 years ago in Latin America. This was about Second Order Auditing in Colombia during the second part of the 1990s. This project was carried out at the Country’s National Auditing Office, and was an application of the Viable System Model and the Viplan Methodology to a National Context. It was an innovative project at the CGR, focused on Second Order Auditing, to improve communications within the fabric (...) of the Colombian government. Its emphasis was building responsible trust between public enterprises, ministries and political agencies. Its emphasis was building communications between ministries and public entities, with the aim of increasing their effectiveness. At its core were methodological and epistemological developments. Key questions it attempted to answer were how to model the complexity of the enterprises and how to transform the auditors’ views of their relations with people in public entities, from one focused on requesting information, to one focused on communications. Structural changes were proposed for the National Audit Office and state enterprises, and hundreds of auditors were trained, through epistemological methodological workshops, in second order auditing and the reports of their auditing were debated extensively in government and beyond. This paper finishes with a short discussion of these transformations in the light of organisational cybernetics and in particular of the Viable System Model. (shrink)
