Answer to Question 2

Rationale: Effectiveness is related to the usefulness of technology in completing desired goals. The efficiency of systems deals with the expenditures of resources, where resources are time, productivity, error rates of users or the costs of the system to the organization in terms of value of the product compared to the purchase price, little used options or redesign of applications. User satisfaction can be assessed by measuring perceptions about the efficiency or effectiveness of interactions with the system.
