Increasing attention is paid to organisational learning as it is widely regarded that the success of contemporary organisations is strongly contingent on its ability to learn and grow. Importantly, informal learning is argued to be even more significant than formal learning initiatives. Given the widespread use of digital technologies in the workplace, what requires further attention is how digital technologies enable informal learning processes. Drawing from Complex Adaptive Systems (CAS) theory, in this paper we advance a conceptual model for examining this important topic. The two dimensional matrix presented provides a framework for both further research on digital artefacts used in informal learning, as well as the design of formative contexts for learning to occur.
