Cognitive task analysis: theoretical and methodological aspects
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2009, Vol 2, Issue 2
Abstract
This paper discusses some of the theoretical and methodological challenges faced by nowadays users of cognitive tasks analysis (CTA) techniques. Despite the fact that CTA is recognised as an important prerequisite for the HCI design process, offering important benefits for quality of a final product, more than often the designers will rather ignore the presentations of CTA techniques provided by sophisticated research reports and papers. A communication effort would be therefore necessary in order to identify and present relevant information for practical applications in a more user-friendly manner, easier to be comprehended, and transferred into practice, with clearer usability bench-marks and more precise directions regarding its integration in subsequent designing stages. It is suggested that a further challenge would be to test various CTA techniques in real design contexts, and asses their effectiveness and efficiency against specific tasks and situations, special design problems and particular organizational structures.
