A sustainable digital future of education is at its high call and various digital tools are being used to establish digital learning – but limited attention is paid to quality and competency for the success of DLs. This study addresses the gap and outlines satisfaction as a function of quality factors (knowledge quality and interactive quality) and virtual competency that in turn leads to net benefits (learning). Digital Learning System (DLs) Success model is proposed by mapping into sequential building blocks of DeLone and McLean IS success model and integrating social cognitive theory. A quantitative online survey data from 156 German and Swedish students confirms that knowledge quality, sociability based interactive quality, and virtual competency play an important role towards students' satisfaction and learning. The salient highlighted factors provide a novel contribution deemed indispensable for DLs success. The findings suggest future research avenues for theory and practice.
