WORKSHOP: Modeling Psycho-Social Dynamics, July 24, 2020

System Dynamics Society Conference 

Pascal Gambardella and David Lounsbury, Co-chairs, Psychology and Human Behavior SIG, System Dynamics Society

Many System Dynamics models need psychological and sociological constructs to achieve their purpose. These constructs include intangibles like trust, motivation and morale. This workshop describes the modeling activities designed to transform these constructs into stock-and-flow structures.

Most examples come from models of reputation for an organization. Relevant constructs include reputation, moral outrage, empathy, expertise, loyalty, transparency and commitment. The purpose of one model is to help companies prepare for and handle a reputational crisis. David Diermeier’s book Reputation Rules (2011) provides the source material for this model. The second model, the “Reputation Offerings and Quality Model” examines the effect of a quality crisis in a company:

Reputation Offerings and Quality Model

A new company wants to hire and keep creative people to design innovative products and services (offerings). Innovative offerings increased the company reputation and win new customers and new creative employees. However, quality problems arose and diverted some of these creative people to work on tedious tasks. They are not happy and their loyalty to this once exciting company wanes. Customers are not happy either, and they sever their relationship with the company. The company’s reputation declines and they have trouble hiring enough new creative people. The situation improves once the company addresses the quality issues. This model shows the use of social and psychological constructs in models.

Workshop materials will begin appearing here on July 6, 2020.
