Task analysis tool for DITA and user experience
IBM Task Modeler is a tool for rapidly creating and analyzing models of human activity as a hierarchy of tasks and related elements.
An information architect can use Task Modeler 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.
