ConcurTaskTrees

ConcurTaskTrees (CTT)^[1] is a notation for task model specifications useful to support design of interactive applications specifically tailored for user interface model-based design.

The main features of ConcurTaskTrees are:

Hierarchical structure
Graphical syntax
Concurrent notation

In Human-Computer Interaction, in the field of task analysis, task models indicate the logical activities that an application should support to reach users’ goals.

ConcurTaskTrees has been mapped into Unified Modeling Language.^[2]

Tool Support

The editing and analysis of task models is supported by the ConcurTaskTrees Environment (CTTE).^[3] The executable code is publicly available and free to download.
