Hierarchical Task Analysis (HTA), Cognitive Work Analysis (CWA) and Goal, Operator, Method, and Selection (GOMS) are the chosen methods. There are comparisons between HTA and CWA, and a general comparison between different techniques of GOMS. At the end, there are conclusions in order to underpin the previous analyses and comparisons.
