Effectiveness is the extent to which a goal, or task, is achieved.
Efficiency is the amount of effort required to accomplish a goal. Satisfaction is the level of comfort that the user feels when using a product and how acceptable the product is to users as vehicle for achieving their goals. Put into my own words, a product or service is highly usable if the product or service can be used as a tool to accomplish a set of defined tasks easily and with a minimum of frustration. Ideally, frustration should not exist at all. Instead, the tool should instill sense of accomplishment upon the completion of the tasks.
