Managing a company requires different tools and methodologies in order to successfully deal with its intangible resources and maintain a competitive advantage. Econometrics, Agent-Based Modelling (ABM) and System Dynamics (SD) are modelling paradigms which allow building dynamic models which is a characteristic of this organisational context. These three paradigms present important differences that could determine their suitability to analyse organisational problems. This paper describes the Econometrics, System Dynamics (SD), Agent-Based Modelling (ABM) modelling paradigms. Next, the paper study how these three paradigms analyse organisational problems by means of a model developed in the three paradigms. Finally, the paper provides a method to validate the assumptions about how the paradigms fit with the requirements to study an organisational problem.
