The dynamic landscape of engineering and technology continuously demands innovative solutions to complex problems. As companies strive for efficiency, cost-reduction and sustainability, automation and uncertainty modelling are becoming pivotal matters in the industrial world. This thesis presents the results of a six-months internship in the Alten Rennes Innovation Department. The primary objective of this internship was finding innovative solutions for the management of requirements in systems engineering. Numerous studies have been conducted on systems failure causes. D Laurie Hughes et al. propose an analysis of phenomenon with the goal of identifying the trends and the main weaknesses of the current approach.
