gPM (generic Process Management) is a generic TOPCASED tool for business process management that can also be used for bug or issue tracking and for other almost any document-based process. gPM is composed of a server and several clients are available (Web-based, Eclipse Mylyn connector, Eclipse rich client). As gPM is a generic tool, it needs to be instantiated for each business process you want to support. Defining a business process consists of providing the product types, sheet types, sheet link types, and the life cycle of each sheet type. gPM configuration also includes roles and access controls, sheet type life cycles, dictionaries and translations, functional extension points, filters, and more. gPM has already been successfully instantiated for both simple development processes (like Mantis or Bugzilla) and complex industrial processes, like in the aerospace domain.

It is quite configurable, making it easy to watch several RT queues simultaneously and post the results to different chat rooms.
