Exploring the Applicability of a STAMP-Based Interorganizational Risk Management Coordination Taxonomy (IRM-CT) from Seaports to Aviation

Interorganizational coordination is essential for safety in complex sociotechnical systems such as airports, where multiple actors interact within shared operational environments. Although aviation operates under the internationally harmonized Safety Management System (SMS) framework established by ICAO, this study explores the applicability of a STAMP-based Interorganizational Risk Management Coordination Taxonomy (IRM-CT), originally developed for seaport operations, within the aviation domain to assess its conceptual transferability across sectors. Through qualitative analysis of the Canadian Aviation Regulations (CAR), ICAO Annex 14, IOSA Standards, and two operational safety management documents from an international airport, five operational adaptor categories (plans and rules, objects and representations, roles, routines, and proximity) are identified as mechanisms supporting interorganizational coordination. Each operational adaptor is complemented by enabling adaptors (structural, procedural, and relational) that institutionalize authority, standardize processes, and sustain trust among stakeholders. The results illustrate how these adaptors collectively align with STAMP control functions, offering a structured means to visualize interorganizational coordination within aviation safety management. While the findings suggest that the IRM-CT may be conceptually transferable to the aviation domain, the analysis remains exploratory and highlights the need for further empirical validation to confirm its broader applicability across transportation systems.
