Analytical evaluation: explain rationale for choice of two methods

[amyjko]

"I was confused as to why two specific methods of design were chosen to be discussed over the rest of the methods. Heuristics and walkthroughs, described as widely used analytical evaluation methods, lead me to ask why these methods were chosen over the rest. The benefits of these methods are later described in the article, but without having a knowledge of the other methods available it is confusing to me as to why these methods in particular hold more weight than the others."
