strategies based on the consumer-satisfaction status

The Evolution of Expectation–Confirmation Model (ECM)

concentrated on post-acceptance variables (such as “post-usage expectations” which the author named as “perceived usefulness”)

The Expectation–Confirmation Theory (ECT)

Diagram/schematic of theory

The Expectation–Confirmation Theory (ECT)1. First, consumers form initial expectation about a

specific product or service prior to purchase

2. Following a period of initial consumption, they form perceptions about its performance.

3. Third, they assess the perceived performance of the product/service

4. Fourth, the consumers form a level of satisfaction.

The Expectation–Confirmation Theory (ECT)- cont.

Positive disconfirmation (performance > expectation)

Simple confirmation (performance = expectation)

Negative disconfirmation (performance < expectation)

ECT Limitations

1. Limitation in explaining IS expectation formation process

2. ECT mainly focuses on consumers’ repurchase intention. It cannot capture the IS products/services quality factors (system quality, information quality and service quality)

3. It needs to be modified in defining the subject as ECT deals with consumers rather than with customers

customer : pays for a product/serviceconsumer: consumes/uses the product/service

The Expectation–Confirmation Model (ECM)

The Expectation–Confirmation Model (ECM)

1. First, after using a particular IS for a period of time the users form a conception of perceived usefulness,

2. Second, the users determine to what extent their perception of usefulness about that IS has been confirmed

3. If the user finds that the product/service is as useful as he/she perceived, he/she forms a notion of satisfaction.

4. Finally, satisfied users intend to continue the usage of that IS whereas dissatisfied users intend to discontinue the service
