IBM Task Modeler is an Eclipse-based software tool for modeling human activity as a hierarchy of tasks and related elements. An information architect can use it to design DITA (Darwin Information Typing Architecture) maps. A usability practitioner can produce either classic HTA (Hierarchical Task Analysis) diagrams or RAG (Roles and Goals) diagrams. A development manager can produce a use case model. The tool can be used in a workshop, during a field study, or at one's desk to rapidly create, explore, analyse, and share these models. Task Modeler is easy to learn, responsive in use, and adaptable to evolving practices. It creates attractive, expressive diagrams that inform and engage design stakeholders.

This technology has graduated. IBM Task Modeler, now known as As IBM Information Architecture Workbench (IAWB), is now available at https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?lang=en_US&source=swg-iiaw.

The design and development of Task Modeler, Version 7, was led by Mark Farmer, a software engineer at IBM in the U.K. Version 6 includes many features that had been developed previously; the development team would like to acknowledge the contributions of Paul Englefield, Mark Tibbits, Nik Mottershead, Anika Kastia, Ian Wells, and Ida Audeh as being key in shaping the direction of Task Modeler.

The team also acknowledges the excellent and ongoing encouragement, support, and guidance from their DITA client (Dave Muir, Dave Schell, John Hunt, Mike Iantosca, and Michael Priestley). They also thank the test participants at Hursley and early adopters world-wide who provided invaluable feedback on the evolving design.
