Purpose – This study aims to map the process functions of the Piglet Breeding Unit. Theoretical framework - The work points out a literary review of resilience engineering, holistic view, process modeling and socio-technical system. Design/methodology/approach – Based on the Functional Resonance Analysis Method (FRAM) and the use of action research as a research methodology to guide the study steps. Findings - The practical application of the study provided the margin projection of for operational maneuvers, allowed the visibility of operations in a macro scope, supported the decision made by managers and instigated to rethink the way each function was performed. The actions proposed through the study meet the process management, seeking to identify and reduce production bottlenecks, from the perspective of production engineering. Originality/value – The mapping of the process with aspects related to each function provided the reflection of actions that would cooperate to the unit manager in defining the best decision to make based on the structure and the degree of importance in the system used. FRAM allows the increasing of the degree and type of variability, allowing you to view the function with the largest number of variables. Keywords - Decision making, management processes, function mapping, productive bottlenecks.
