The Hierarchical Task Analysis (HTA; Sheperd, 2000; cited in Mills, 2007) is used as a framework: Firstly, psychological issues related to using the TM are discussed. Secondly, an usability analysis of the TM is conducted, whereupon principles of usability (Jordan, 1998) are applied. The result is that the design has major issues. Subsequently, an improved design is sketched out - considering identified issues. Finally, an evaluation method for the redesign is introduced.
