Abstract

In this paper, we analyze the data (failure and correction reports) collected on the software of three successive generations of the Brazilian Switching System -- TROPICO-R, during validation and operation. A comparative analysis of the three products is done and the main results are outlined. Emphasis is placed on the evolution of the software and the corresponding failures and corrected faults. The analysis addresses the modifications introduced on system components, and the distribution of failures and corrected faults in the components and the functions fulfilled by the system.
