Module 1 - Best Practices of Software EngineeringWhy Model Visually?Why Model Visually?• Captures structure and behavior• Shows how system elements fit together• Keeps design and implementationconsistent• Hides or exposes details as appropriate• Promotes unambiguous communication• The UML provides one language for allpractitionersMastering Object Oriented Analysis and Design with UMLCopyright © 2003 Rational Software, all rights reserved19Modeling is important because it helps the development team visualize, specify,construct, and document the structure and behavior of system architecture. Using astandard modeling language such as the UML (the Unified Modeling Language),different members of the development team can communicate their decisionsunambiguously to one another.Using visual modeling tools facilitates the management of these models, letting youhide or expose details as necessary. Visual modeling also helps you maintainconsistency among system artifacts - its requirements, designs, and implementations.In short, visual modeling helps improve a team’s ability to manage softwarecomplexity.1 - 19
