Third Generation Knowledge Management Systems: Towards an Augmented Technology Acceptance Model

Abstract

The paper examines the applicability and sufficiency of the Technology Acceptance Model (TAM) in the context of social software and newer generation knowledge management systems (KMS). A reinterpretation of the two TAM constructs "Perceived Usefulness" and "Perceived Ease of Use" in light of expectancy-valence theory reveals that the TAM predominantly focuses on performance expectations on different behavioral levels and, thus, fails to account for the entire range of drivers and barriers related to KMS usage.
