Origin and Evolution of Policy Simulation: A Personal Journey

Abstract

The past half-century has seen remarkable growth in the use and acceptance of simulation games for policy intervention. This article provides one observer’s perspective on the evolution of the discipline: literature, theory, and practice. The creation and growth of ISAGA are also referenced. Early computer simulations failed at prediction due to limitations of theory, data, and technology. Their lack of transparency limited their value for expository purposes. Through time, a design methodology has emerged to guide the creation of simulation games to improve communication in complex policy decision environments. These instruments are not intended to be predictive; rather, their primary objective is to help a group achieve consensus through the multilogue mode of communication. Several simulation/games are outlined to illustrate the progression of the discipline.
