Action learning sets are a simple and powerful way for individuals to learn from each other. They are a popular method in the field of action learning. Action learning is a process which involves working on real challenges, using the knowledge and skills of a small group of people combined with skilled questioning, to produce fresh ideas and reinterpret familiar concepts. Initially developed by Reg Revans, it follows the process outlined in this diagram of explicitly stopping to reflect back on actions taken, drawing out learning from that reflection, and applying that learning to planned practice.
