Factors Influencing Information Systems Continuance

Core Determinants of IS Continuance

According to the Expectation-Confirmation Model (ECM), the intention to continue using an Information System (IS) is driven by three primary factors: user satisfaction, degree of confirmation of expectations, and post-usage perceived usefulness.

The Dominance of User Satisfaction

Satisfaction acts as the strongest predictor of IS continuance. While perceived usefulness represents cognitive belief, satisfaction represents an affective response that carries more weight in user decision-making.

Impact of Initial Experiences

Initial expectations and the subsequent confirmation of those expectations are crucial antecedents to satisfaction. Conversely, negative experiences related to performance issues—such as poor website design or slow internet speed—directly lead to dissatisfaction and a decreased likelihood of continued service usage.
