Introduction What is UML? Facts

© 2006 Progress Software Corporation7 ARCH-2: UML From Design to Implementation using UML  Manage complexity  Mitigate risk  Facilitate communication  Modeling provides ability to visualize entire systems, assess options and designs Software has grown from do-it-yourself into highly complex systems Software is integral part of business process, so has to be well planned Software has become capital equipment that cannot just be removed/changed Introduction Why model?
