The document presents a hierarchical decision model for evaluating the priority of operational risk management elements in banking institutions in Mexico. It addresses the identification of decision criteria and operational risk management (ORM) elements related to estimating errors caused by individuals, systems, processes, and external factors in the Mexican banking industry, which result in significant losses. Therefore, it is of utmost importance to promote the strength and stability of institutions. The identification of basic decision criteria and risk management elements regarding the effective implementation of operational risk management systems (ORM) in financial institutions was addressed. The research design involved empirical data acquired through interviews with risk assessors in the banking institution. The methodology used is the Analytic Hierarchy Process (AHP), which identified a list of four decision criteria and 13 subcriteria of operational risk management and evaluated their relative importance. One of the findings is that the main criterion for avoiding errors in Operational Risk Management is the personnel factor. AHP proposes a self-regulatory approach for the measures requested by regulatory bodies.
