The earlier phases of any product development greatly influence its life cycle, especially in the aerospace field. Therefore, precise requirements are critical for good acquisition/development contract execution. Firstly, this study has made use of OPM (Object Process Methodology) to model the current Brazilian Air Force Policy for aerospace products’ life cycle and a robust hazard analysis technique (STPA – System-Theoretic Accident Model and Processes) to investigate the causal factors which lead to negative impacts on the contract elaboration process for military aerospace products in Brazil. STPA uses System Theory to model any process as a feedback control structure. Focusing on the minimization of losses, the method considers the hazards, safety constraints, unsafe control actions, and causal factors. Based on that, it proposes requirements (which can be understood as recommendations), showing a path throughout the earlier phases of the Brazilian military aerospace products life cycle to improve the contract elaboration process.
