Examining the Effects of TAM Constructs on Organizational Software Acquisition Decision

Abstract

The use of multicriteria decision analysis (MCDA) methodology is not uncommon in organizational decisions. However, information systems (IS) researchers have focused on statistical hypothesis testing in examining organizational technology adoption decisions. In this study, an MCDA methodology is adopted in examining the effects of the technology acceptance model (TAM) constructs on organizational software acquisition decision. Analytic hierarchy process (AHP) provides an evaluation model based on the experiential knowledge of domain experts. The results of the study show that software performance plays a significant role in the software acquisition decision matrix, while vendor characteristic is given the least priority. The study also points to the fact that perceived usefulness is more vital than perceived ease of use in software evaluation and acquisition.
