But why do we model? Rather, what are the purposes behind UML modeling? Well, UML is a modeling language and a universally accepted standard used to provide a structure to the entire system, manage complexities of the system and cut down on the development costs. However, most of the software projects developed around the globe do not follow any specific modeling technique to avoid the perceived risk and complexity in Object Oriented modeling of large systems. The semantics defined in the language are based on the software systems; they do not have complete support for systems of other domains. Moreover, the UML is still incomplete in its support for components. "While modeling software is useful, it will not solve all design issues. Smart people and a good methodology are a must. But if used correctly, UML and the modeling process can help improve quality, completeness, and scalability and reduce production time in many software projects."
