Your goal in this assignment is to critique a commercially available software application or other computing apparatus on its "learnability", "flexibility", and "robustness". These three terms are used in Dix et al.'s textbook as three main categories of "principles to support usability" (see section 7.2, beginning on page 260). For each of these categories there is a further set of “principles affecting [category]” (see Tables 7-1, 7-2, and 7-3).
Your critique should begin with a summary of the principles, crafted in your own words but with reference to Dix et al.'s ideas. Following this, provide six (6) detailed examples from the chosen application or apparatus, two for each principle. For each two, one should demonstrate how a principle is correctly applied, and one should demonstrate how a principle is incorrectly applied. Use screen snaps or other visual aides to support your examples. Your examples may be taken from different applications. It might be useful to organize your example in a table or tables, but this is for you to decide.
