1) The document discusses evaluating the effectiveness of information systems by assessing whether they are achieving planned goals, using resources properly, and having the right controls selected.
2) Effectiveness can be evaluated through both relative and absolute approaches by comparing performance before and after implementation or directly assessing goal accomplishment.
3) Key factors that may indicate ineffectiveness include excessive downtime, slow response time, high maintenance costs, inability to interface with new software/hardware, unreliable outputs, and frequent need for maintenance/modifications.
