One of the primary benefits of working with a suite of programs such as Office XP is the interoperability that the suite's programs offer. Because easy and efficient integration and interoperability exist between the Office applications, you can use all the applications together to build more effective documents. PowerPoint may be the one application within Office that makes the greatest use of the other applications within the suite. By its nature as a presentation tool, PowerPoint can work with all your other applications, tools, and documents to create a single powerful and effective slide presentation.
