This document outlines the agenda and instructions for a Lego simulation workshop to teach the Cynefin decision-making framework. The workshop consists of 4 rounds of Lego building exercises designed to demonstrate the different domains of the Cynefin model and the appropriate decision-making approaches. Participants will work individually and in teams to build structures, vehicles, animals and plants under various constraints that simulate complex, complicated, chaotic or obvious problem domains. The objective is for participants to experience when different domains and leadership styles are called for.
