Dynamics of Emergency Department Crowding Initial Simplest Simulation of the View from the waiting room. Start of a simple introductory series which proceeds to IM-338  A simple CLD is at IM-340

Aim: To gain insight into what map and model representations in applied systems methods in IM-1267 can assist identifying and explaining the improvement strategies (leverage points) described by Donella Meadows Places to Intervene Article. The context is social learning for collective action to improve real world events. Information Sources are adapted from IM-920

From fighting lions (fight or flight) to fighting feedbacks in complex systems. A single person cutting the Gordian knot to the dynamic complexity of rubik's cube. Think of multiple players with multiple misperceptions of the faces on the cube and conflicting goals about what the desired solution is. Worse still, without an accepted framework we dont even know if it's a cube or another structure. See also policy resistance IM-697
