HTA as a framework for task analysis
Article Abstract:
The status of the Hierarchical Task Analysis (HTA) as a general framework for examining tasks and its relevance to analyzing cognitive tasks were evaluated. The framework presented related the various stages of decision-making encountered in a practical project which includes cost-benefit analysis, exploring behaviors and task redescription. Utilizing the framework resulted in the hierarchy of operations and plans that characterized HTA. Thus, HTA is justified as a general task analysis strategy rather than a method for modelling behavior.

Applied cognitive task analysis (ACTA): a practitioner's toolkit for understanding cognitive task demands
Article Abstract:
Applied Cognitive Task Analysis (ACTA) consists of three interview methods that help the practitioner extract information about the cognitive demands and skills needed for a task. It allows the practitioner to represent the information in a format that will translate more directly into applied products. ACTA techniques were found to be flexible, easy to use and provide clear output. Training materials and information obtained from the ACTA interviews were accurate and important for training purposes.
