<![CDATA[In the current era of pervasive digitalization, organizations increasingly depend on digital communication technologies to coordinate distributed knowledge and accelerate strategic response within complex organizational ecosystems. Although digital transformation has attracted extensive scholarly attention, most studies examine digital communication capability, knowledge sharing, organizational learning, and strategic decision-making as separate constructs, leaving their combined, cross-level influence on organizational adaptability under-theorized. This article develops a multilevel conceptual model linking digital communication capability at the individual and team level, cross-functional knowledge sharing at the group level, organizational learning at the organizational level, and strategic decision-making at the managerial level, culminating in organizational adaptability as the ecosystem-level outcome. Using a systematic literature review of peer-reviewed journal articles published between 2021 and 2026 and indexed in reputable databases, this study maps theoretical linkages among the constructs and identifies mechanisms through which digital communication capability cascades upward to shape adaptive capacity. The novelty lies in integrating communication theory, dynamic capability theory, and organizational learning theory into a single multilevel ecosystem framework rather than treating digital transformation as a purely technological phenomenon. Findings show that digital communication capability functions as a foundational micro-level enabler that, combined with structured cross-functional knowledge sharing and continuous organizational learning, strengthens the quality and speed of strategic decision-making and thereby enhances organizational adaptability.]]>
