Recent years have seen tremendous growth in knowledge management projects within the NHS. Project staff must acquire rapidly a wide range of task-related skills. Conventional training courses may be inappropriately timed or unavailable to project staff. Action learning provides a group-based means of meeting skills deficits associated with project management and delivery. This paper describes an action learning set for project staff on five knowledge management projects within Trent Region. A brief evaluation aimed to identify most and least useful and most and least enjoyable features of the action learning set. Comments on the facilitation and the content of the action learning sessions are analysed. Action learning is feasible in meeting the training needs of project staff. It may also provide a means of meeting the shared learning needs of communities of practice within a virtual environment. Knowledge management does not merely involve management and delivery within innovative projects but also requires exploiting shared learning across projects.
