Methods of Ranking usability attributes — A comparative study

The impact/role of each usability attribute may vary during the usability evaluation process and has to be quantitatively evaluated to decide relative importance of each attribute in development process. Thus, to rank usability attributes there exist an algorithm “CompuRank” and Scenario Based Ranking Method (SBRM) for ranking usability attributes in software development process. However, it is required to unify and authenticate the ranks of usability attributes computed using these methods. A survey based approach has also been proposed that empirically estimates ranks by collecting the opinions of software professionals from various organizations. In this context, we compare the ranks of usability attributes computed using “CompuRank”, SBRM and survey based approach with intention of unification and substantiation of ranks. It leads to reach at agreeable ranks of usability attributes during development of usable software.
