Global, organisational and technological changes are transforming the world of work, which elevates the need for lifelong professional learning. Professional learning is expected to increase by 50% globally by 2040 (AlphaBeta, 2019). This demand is unlikely to be met through established forms of professional development, such as training and workshops that traditionally have enabled large numbers of people to reach a specific level of competency. There is a general recognition that simply scaling up conventional forms of professional development, such as training or degree programmes that require a long-term, full-time commitment, will not provide the volume or variety of professional learning needed. In the past, learning a standard curriculum has been helpful to enable large numbers of workers to learn skills and knowledge that apply to standard work practices. However, largescale training of a standard curriculum is not helpful for workers who need to learn specialist knowledge and individual work practices (Littlejohn & Margaryan, 2014). Each professional has to learn specific skills and knowledge to apply to niche problems and work tasks.
