I would like to build on Bob Walkers comments on Risk Work. My views are based upon several key observations: 1) Organizations and individuals in organizations often evolve into shockingly narrow paradigms (and visions of their work and business environment) over time. 2) This limits vision such tha...

A low exposure variable would have limited exposure to influence by other variables. In certain mental models, selling price may be a low exposure variable -- for ...

At SDSG, LLC (The Strategic Decision Simulation Group), we have been refining methods for identifying leverage points in systemic models for several years. James Ritchie-Dunham of SDSG will be presenting a paper on our methodologies at the International SD conference in Istanbul in August. In Donell...
