The quality of requirements and the effectiveness of verification and validation (V&V) techniques in guaranteeing that a final system reflects its established requirements have a direct influence on the quality and dependability of the delivered system. The V&V process can be efficient from a managerial point of view, but ineffective from a technical perspective, and vice versa. This paper presents an end-to-end formal computer-aided specification, validation, and verification (SV&V) process, whose feasibility and effectiveness were evaluated against the flight software for the Brazilian Satellite Launcher. Unified modeling language (UML) statechart assertions, scenario-based validation, and runtime verification are used to formally specify and verify the system, and metrics of the ongoing process and its V&V results are collected during the application of the process. The results of the case study indicate that the process and its computer-aided environment were both technically feasible to apply and managerially effective, will likely scale well to cater to SV&V of mission-critical systems that have a larger number of behavioral requirements, and can be used for V&V in a distributed development environment.
