Life-cycle cost analysis can provide a solid basis to support improvements in how fleet managers use their vehicles and in how manufactures design them. The challenge to it be an established practice rests on getting quality data provided by fleet operators and on the understanding that the data is significantly influenced by both the operational environment and the quality of management (operations and maintenance). In 2012, a benchmark study was conducted using the public transportation system of Salvador, Bahia, Brazil. Twelve companies participated in the study. Although the primary purpose of the study was to assess the differences in the competitiveness among the twelve companies, the data collected provide a database that was very consistent in providing critical analysis of vehicle maintainability by generating life-cycle cost analysis. The study proved to be an important tool to link vehicle design to the operational and maintenance management of company fleets.
