The endogenous perspective: a friendly amendment

By Jack Homer, VP of Professional Practice I have developed lots of SD models over the years for both private and public organizations.  My models have all been built to answer strategic questions for which there was no single obvious answer, due to the presence of dynamic complexities including accumulations, delays, nonlinearities, and feedback loops.  … Continue reading The endogenous perspective: a friendly amendment

By Jack Homer, VP of Professional Practice I was once consulted by a semiconductor equipment maker who wanted to reduce their service maintenance costs.  The client team offered a variety of ideas, some of which were workforce-related and could be implemented fairly rapidly, while other options involved product improvement and would require several years of … Continue reading Let’s consider policy feasibility

Six Reasons to Apply System Dynamics Modeling in Medical Research

By Kenneth G. Cooper (Moderator's Note: After several recent conversations with Ken about different dimensions of SD in medical research, and as a follow-up to his recent post, I asked him to provide a short list of the top reasons why we should pursue more SD work in this area. The list below, shared with … Continue reading Six Reasons to Apply System Dynamics Modeling in Medical Research

The need for SD modeling of human biological systems and diseases

By Kenneth G. Cooper It is within our capability to reduce dramatically the long time and high cost of successful drug development for treating human disease. We can do so by adding to medical research the analysis of the elegantly complex, feedback-intensive systems of the human body—not just as a collection of components, but as … Continue reading The need for SD modeling of human biological systems and diseases

First, look at the data

By Jack Homer, VP of Professional Practice I recently received an e-mail from a college student, someone I’d never heard of before, wondering whether system dynamics was the right approach for studying a particular issue: how the government’s publication of secondary school rankings in his country might influence parents’ attitudes and behaviors.  The student wondered … Continue reading First, look at the data
