Task Analysis tools

[Stuart Burnfield]

Hi Wade -

"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. 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."

BTW an excellent book on task analysis is "User and Task Analysis for
Interface Design" by Ginny Redish and JoAnn Hackos. Despite the title, it's
equally useful for tech writers.
