Building a model forces a scientist to think about how the parts of the model interrelate and interact with each other. This may help the scientist to formulate better questions about the real system. In addition it is usually far easier to manipulate a model than it is to make changes to a real system so that the implications of those changes can be studied. Once the scientist believes that they understand the model, or suspects that the model has exhausted its usefulness, they can either build a better model or try testing some hypotheses in the read world.
