Abstract

Evaluation of the software usability as concerns software alternatives represents a typical Multi-Criteria Decision-Analysis (MCDA) problem. Such a kind of problem can be successfully facedvia structured models and approaches which validity have been widely shown in literature. Inthis work, a methodological framework based on a MCDA model integrating the DEMATELmethod along with the ANP technique is proposed and explained with more detail to address therelevant issue of the software usability evaluation. The applicability of the consideredDEMATEL-ANP (DANP) based model in the under analysis contest is demonstrated via apreliminary investigation, where the usability of the two major Mobile Operating Systems(MOSs) is compared and quantitatively prioritized. Results of both performed comparisonmethod and sensitivity analysis confirm the validity of the proposed MCDA model as wellrobustness of its outcomes. Moreover, results obtained point out about the influenced,independent and core factors for the MOSs usability, as well as strengths, weaknesses anddiscrepancies in the usability as concerns the two investigated alternatives. Representing theseoutcomes crucial aspects for driving focused MOSs usability improvement processes andstrategies, they give also evidence of the effectiveness of the proposed methodologicalframework.
