The Rational Process Workbench Product
The Rational Process Workbench® (RPW) tool helps you customize RUP for the precise requirements of your organization by leveraging your own expertise, practices, and internal knowledge. If you have a license of the RUP product, you can obtain the RPW product by downloading the software from the Rational Developer NetworkSM. The features of the RPW product are described below.
RUP Organizer 
For basic customizations, the RUP Organizer feature within Rational Process Workbench allows you to simply drag and drop your own artifacts or process examples into your RUP configuration. The easy-to-use RUP Organizer interface helps you to develop and publish a RUP Plug-In to share with your team, your organization, or with the RUP community on Rational Developer NetworkSM. Instead of developing and maintaining separate internal knowledge bases or artifact repositories, RUP Organizer makes it easier than ever to manage and deploy custom process content within the RUP framework.
RUP Modeler
For teams wanting to develop significant process customizations, the RUP Modeler feature brings the powerful modeling capabilities of Rational® XDE(TM) to process engineering. You can drag and drop workflows, artifacts, and relationships to represent your development process visually. Once you have modeled your organization's custom development process, Rational Process Workbench lets you deploy the results as a custom RUP Plug-In.
Process Engineering Process
The Process Engineering Process (PEP) is the third component of the RPW product. PEP is a RUP-like process description providing guidance in the area of process engineering. It describes how to use the extended RUP tool set to extend and customize the RUP framework to your development organization and how to implement this customized process in your software development environment.
