ABSTRACT

The system dynamics models belong to the systems approach. These models allow analysing trends of the relevant variables under different programme settings and scenarios. In this research, a new methodology is proposed to apply the system dynamics modelling ―which stands for a quantitative approach― by bringing another methodology ―which is qualitative― and is able to incorporate the different perspectives existing about the programme as well as the cultural aspects whose effects on the impacts of any development programs has already been extensively studied. Bringing the Soft Systems Methodology ―which also belongs to the systems approach― allows getting models that are closer to reality, and whose explanatory power on the effects of programme models is greater.
