The objective of the present work is to analyze the global efficiency of a manufacturing cell of a Brazilian automotive industry. The specific objectives are: (i) analyze the cycle time per operation in each product, (ii) analyze the operations of the cell versus demand. For this, the capacity management model proposed by Pacheco et al. (2012), which integrates the concepts of Theory of Constraints and Total Productive Maintenance (TPM). The practical application of the model is relevant as the definition of the productive capacity of systems enables better management of resources and capacities, improve production scheduling on the factory floor and meeting the demands imposed by the market. The results obtained allowed to prove the effectiveness of the model. It was possible to determine the capacity of the productive system and the impact on the productive capacity of the whole system, considering the quality nonconformities that occur after the bottleneck of the productive flow. The IROG as a tool makes it possible to take more assertive actions in problem solving, optimization of the use of industrial resources and greater integration between the different areas that encompass manufacturing.
