The process begins with the original mental model (State 1), which is disrupted by an insight trigger (Phase 1), moves into a liminal space characterised by reframing, reflecting and signal processing (Phase 2), leads to insight formulation (Phase 3) which contributes to an adapted mental model of the problem or situation (State 2).
