1. Effectiveness and efficiency may influence satisfaction. For example, low effectiveness or low efficiency may lead to low satisfaction. Satisfaction may influence effectiveness and efficiency. For example, frustration may cause users to quit a task, which influences effectiveness.
2. Satisfaction is often measured using a questionnaire. See the examples in the definition of questionnaire.
3. The difference between satisfaction and user experience is that satisfaction results from use, while user experience results from discovering, adopting and using the interactive system, through to final use and recollections of use.
