The balance between costs incurred and the service provided to the customer depends on the identification and exploitation of logistics cost trade-offs. In this sense, the goal of the present study was to identify the extent to which Brazilian logistics professionals understand and assess cost trade-offs. To this end, a questionnaire based on the theoretical framework was administered to a sample of 73 professionals at commercial and industrial companies that were included on the list of the largest Brazilian enterprises in the 'Melhores and Maiores' (Best and Biggest) edition of Exame Magazine. The questionnaire's reliability was ascertained using Cronbach's Alpha (90.8%), and the data thus gathered were quantitatively analyzed through descriptive statistics and the non-parametric Mann-Whitney test. The results showed that most logistics professionals know that there are trade-offs but lack a broad understanding of the concept, especially with respect to the relationship between trade-offs and total cost. Nonetheless, the knowledge that logistics have an impact on economic-financial performance appeared to be widespread for most of the sample, particularly among experienced professionals. The results also revealed that although trade-off assessments are emphasized when designing and redesigning logistics processes and networks, these assessments are still limited in regard to the formulation of specific projects. The non-use of cost simulators and lack of adequate cost information were identified as factors related to the limited assessment of trade-offs. These findings are important because they demonstrate that a company's controllership can help logistics professionals to reverse this situation of non-assessment of trade-offs and to strive for the optimization of economic results.
