Complementing the process engine were the Mediation Modules. In an SOA environment, services rarely interact perfectly; data formats differ, protocols clash, and logging requirements vary. Mediation modules acted as intermediaries that could transform data, route messages, and perform logging without modifying the actual service endpoints.
WPS is not a standalone product but an extension built upon the . While WAS provides the underlying Java EE environment (hosting servlets, EJBs, and web services), WPS adds a layer specifically for business integration. IBM Redbooks websphere process server
By utilizing WebSphere Integration Developer (WID) as its associated tooling, developers could visually assemble these integration flows. This "configuration over coding" approach allowed business analysts and developers to collaborate more effectively, dragging and dropping components to define how data moved between, for example, a legacy mainframe system and a modern SAP implementation.

Furthermore, WPS included a robust Business State Machine engine. While BPEL handled sequential processes, state machines managed event-driven logic, allowing systems to react to specific triggers rather than following a strictly linear path. This dual capability ensured that WPS could handle both rigid, transactional workflows and dynamic, event-driven scenarios. WPS is not a standalone product but an
