Why Model?

Conceptual modeling forces all participants to critically evaluate the current (and potential future) business requirements of an organization. An effective conceptual model will also provide an organization with a solid schematic of its data needs, independent of any other considerations (i.e. application programming; vendor-specific database management systems). Additional benefits include: [21]

Benefits of Effective Modeling

Cliff Longman of Adaptable Data believes there are simply three key benefits of effective modeling: A definitive definition; shared understanding; and a low-cost method of testing “What If” scenarios [22].

Consequences of Poor Modeling

While effective modeling can be challenging, the consequences of poor modeling (or not modeling at all!) can be severe, particularly over the longer term. A couple of these consequences include:

Those are a few of the benefits of proper modeling and consequences of poor modeling. Again, the modeling process may require significant time and resources. However, over the longer term, the benefits of sounds modeling should outweigh the costs for most organizations. The next section will illustrate two examples of how proposed information systems benefit from the iterative nature of conceptual modeling.
