Explanation:
Models do not behave exactly like the things they represent. Accuracy—In order to make models simplistic enough to communicate ideas some accuracy is lost. For example, ball and stick models of atoms do not show all the details that scientists know about the structure of the atom.
Modeling Benefits
Viewing systems from multiple perspectives.
Discovering causes and effects using model traceability.
Improving system understanding through visual analysis.
Discovering errors earlier and reducing system defects.
Exploring alternatives earlier in the system lifecycle.
