Internal Communication as a Driver of Organizational Resilience : a systematic literature review using PRISMA method[La communication interne comme moteur de la résilience organisationnelle : une revue systématique de la littérature utilisant la méthode PRISMA]

In an ever-changing environment dominated by uncertainty and complexity (VUCA), the ability of organizations to anticipate, prepare for, and adapt to crises is a major strategic asset. Among the internal levers that can support this resilience, internal communication plays a central role by facilitating coordination, engagement, and meaning-making in the face of disruption.This article provides a systematic review of the literature aimed at clarifying the role and functions of internal communication in strengthening organizational resilience. Conducted according to the PRISMA protocol, the study draws on the Scopus database and examines recent publications from the last five years devoted to the relationship between communication practices and adaptability. This approach helps to structure a still fragmented field of research by identifying the most significant theoretical and methodological approaches.Beyond a critical synthesis, the article offers a frame of reference for better understanding the communication dimensions of resilience and informing the design of strategies adapted to uncertain environments. By emphasizing the importance of considering internal communication as a strategic function, this work opens up a perspective for consolidating organizational preparedness and supporting continuity in contexts of crisis or sudden change.
