Abstract
Over a period spanning approximately twenty five years IS researchers have been plagued by the problem of how to evaluate IS effectiveness or success. After the advent of the WWW in the 1990s, questions have arisen regarding the relevance of previously established evaluation approaches to the evaluation of web-based IS. In this paper, we describe a holistic approach to Information Systems (IS) evaluation, focusing on web-based applications. In this context, a holistic perspective refers to a multi-stakeholder evaluation regarding perceptions of IS Success. The paper presents the results of a study in which a web-based IS at a national telecommunications company in South Africa was evaluated using e-Service Quality (e-SQ) constructs. The study demonstrates the operationalisation of an e-SQ instrument for the purposes of evaluating IS effectiveness amongst multi-stakeholders. Evidence is provided that measuring attitudes of different stakeholders provides a more holistic perspective of IS success.
