What are goals? • Goals are the reason why we perform tasks • Tasks are not goals
Task-Directed Design • What are the tasks? • Programmers do task-directed design • Good programmers, of necessity, see things procedurally, or task-wise
Examples of False Goals • Save memory • Save keystrokes • Run in a browser • Be easy to learn • Safeguard data integrity • Speed up data entry • Increase program-execution efficiency • Increase graphic beauty • Maintain consistency across platforms
