Object models breaks down a project into buts in a very simply and easy to understand format thereby increasing the efficiency of development tools and skills and also in no small way reduce production/development time taken to bring the software project into reality.According to H. Chestnut (1965), “A model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered.” This tells us that an object model goes beyond the functional parts of a system as it also covers a very large chunk of the non-functional parts of the to-be-developed system. Object models help all stakeholders of a software development project to have a better understanding of the requirements. This in return assures the feedback of all stakeholders and in no small way reduces development cost (in time and money). Object models can be informal or formal.  Object models also depict special attributes like inheritance and hierarchy of the components that makes up the system. The more complex the project the more imperatively valuable object model becomes.Also coming from Brian Wilson (1984), “A model is the explicit interpretation of one’s understanding of a situation, or merely of one’s ideas about that situation. It can be expressed in mathematics, symbols or words, but it is essentially a description of entities and the relationships between them. It may be prescriptive or illustrative, but above all it must be useful.”Over time, it has been justified that having a good object model is a highly profitable step to developing/delivering a good software product. Embracing the use of object models results in unquantifiable success goes beyond customer satisfaction and developers’ fulfillment.        TABLE OF CONTENT
