Too many industrial projects still fail, mainly due to the managerial techniques used. Indeed, organizational processes are more or less specifically mentioned in systems engineering standards, but in practice, project managers tend to rely more on their own standards, which sometimes set forth practices that do not align with those of the systems engineering domain, hence the reported discrepancies that very often lead to project failure. Thus, we argue that, to improve the companies’ competitiveness when developing new products, cooperation between processes related to system development and project management is key to achieving performance and success. This article presents arguments that tend to support this assertion and introduces an ongoing project to develop both a method and tool that aim to integrate both domains.
