Complementary products to extend IBM WebSphere Process Server capabilities include:

• WebSphere Integration Developer is a new tool (based on Eclipse technology) for rapid assembly of business solutions that allows you to describe all styles of processes with one programming model based on Business Process Execution Language (BPEL). It requires relatively minimal skills and offers rich features for integrated development, testing, and deployment to WebSphere Process Server Version 6.0.
• WebSphere Business Modeler allows business managers to design and simulate processes. This tool includes “drag and drop” business process modeling, providing a structured environment that allows easier participation in business process design. In-class simulation and analysis allow you to “run” the process with real business constraints, allowing you to obtain valuable business performance information.
• WebSphere Business Monitor allows you to monitor the implemented business processes for continuous improvement. The product allows you to receive real-time information about processes in a graphical business dashboard view. You can set up performance thresholds and when performance drops, you will receive alerts.
• IBM Rational Application Software Developer for WebSphere Software is powered by the Eclipse open source platform, allowing developers to adapt and extend their development environment to match their needs and increase productivity. When used with the IBM Software Development Platform, developers can access a broad range of requirements and change management functions directly from Application Developer.
• WebSphere Partner Gateway allows you to connect to your global trading partners and other businesses via electronic data interchange (EDI). The product enables business communications by transforming data between ROD, XML, and EDI formats. 
• WebSphere Enterprise Service Bus (ESB) is a flexible connectivity infrastructure for integrating applications and services. It is designed to enable the development of a Service Oriented Architecture (SOA). WebSphere ESB is at the heart of an SOA, powering it by reducing the number and complexity of interfaces. It allows you to focus on your core business, rather than your IT.
• WebSphere Adapters help you broaden the reach of business processes by easily integrating with business applications and technologies.
• WebSphere MQ provides standards-based reliable and secure connectivity between applications and systems, giving access to more than 80 different platform configurations.
• WebSphere Message Broker helps extend your connectivity between applications by integrating a wide range of applications and various data formats with high performance transformation and routing.
• WebSphere Portal Server helps you present business processes as portlets for easy consumption by customers, partners, and employees.
• WebSphere Host Access Transformation Services (HATS) provides all the tools you need to quickly and easily extend your host applications to Business Partners, customers, and employees. You can make your host application available as HTML through the most popular Web browsers, or expose your critical host data or transactions as a Web service.
