Business managers often find it impossible to communicate business objectives and specify their software requirements to technical members of staff. This beginner"s guide to the Unified Modeling Language (UML) - the standard for documenting software designs - teaches readers to communicate with software developers in a more focused, effective way. It describes the basic diagrams of the UML modeling notation and shows how they are used to specify requirements in an unambiguous way. When applied on a project, the risk of failure through unclear requirements is removed. If you are a non-technical person with a stake in the success of a software project, this book is for you.
