Perceived system performance a test of an extended technology acceptance model

In this study, we introduce the notion of perceived system performance (PSP) to extend the technology acceptance model (TAM). We found that PSP explained 46% of the variation in ease of use, a 50% improvement over our current understanding of ease of use while using only one predictor. We also found...

Summary:In this study, we introduce the notion of perceived system performance (PSP) to extend the technology acceptance model (TAM). We found that PSP explained 46% of the variation in ease of use, a 50% improvement over our current understanding of ease of use while using only one predictor. We also found that, when PSP is absent, TAM was validated as usual. However, when PSP is present, the relationship between ease of use and technology acceptance became insignificant, a phenomenon called conditional independence . We provide a causal reasoning-based explanation for our findings.
