Summary:  Developing applications using the Rational Unified Process is a lot easier if you have the right tools to help you throughout the entire process. The Rational Toolset provides a range of tools that can be employed to help produce the application in different phases of the development process. On their own, these tools provide excellent support for each phase of the Rational discipline. But when used together the tools are even more powerful. By sharing the information you can track components in the application from their original requirement specification through to testing and release. In this first part of a five part series you'll learn about the integration between RequisitePro and Rational XDE.

Summary

RequisitePro is an excellent way to record requirements for an application. Rational XDE is an excellent method of modeling these requirements into Use Case diagrams. On their own, each product fulfills it's part of the development process.

Together, however, they provide an excellent way for developers and designers to communicate with project leads and ultimately customers to identify and build the application that was requested by the client.

Once the integration is up and running, through the traceability matrix, you can see at a glance which components are modeled and complete, and which parts of the requirements need additional work to build and model the application. Without this level of integration, the development of the application runs the risk of straying away from the original specification for the application.

This is the first part of the series. You still have work to do as you continue to build the Auction system. For the moment, you have a list of requirements and the associated models in RequisitePro and Rational XDE. As you continue to work through building the Auction application in future parts of this series, you'll see more detail at how to turn your Rational XDE model into a working design and code, and how you can integrate the model and coding process into ClearCase to track changes and revisions.
