The Golden Circle is a concept for effective leadership popularised by Simon Sinek but also similar to Julia Atkin’s much earlier concept for enacting values and vision-driven development in schools. Both Atkins and Sinek use three concentric circles with ‘why’ in the centre, ‘how’ in the second, and ‘what’ in the outermost circle. These three questions guide the process of reflecting and crafting a shared vision that the organisation can collectively work towards.
