In cybernetics, models are usually generic and formalized, and they are based on a mathematical or simulative foundation. Therewith, theories which emanate from a process of theorizing that is based on explicit formal modelling have a potential to be stroinger in terms of both robustness and reach than theories that are largely based on implicit mental models.
Criteria for assessing the quality of a model include :
- Validity (its ability to reproduce the historical data of the system to be modelled, under both normal and extreme conditions)
- The acceptability of the assumptions that have been made when defining the model
- Parametric isomorphism (The plausibility of the numerical values adopted for the parameters of the model)
