A model is a formal, abstract, hypothetical description of a complex entity, system or process. Any system can be represented through a number of different models, depending on the level of abstraction required and the intention behind how the model is to be used. Examples of everyday models include climatic models as expressed in weather forecasts, models of ecosystems, economies, stock market simulations and other complex systems. While you can expect to study many different models during your career, it is important to understand the following principles about all models:
- A model is an attempt to explain the dynamics of "what is going on". It can never really explain what is really "going on".
- A Useful Model that is shared, openly discussed and deconstructed leads to a common understanding and insight.
