logical organization, and draw attention to warnings
Can degrade resolution and fidelity with different display units and can be a problem for color blindness
Includes blinking, audible tones, color differences, intensity differences, size differences, font differences, boxing, underlining, ALL CAPITAL LETTERS, offsetting positions, and

Design Specifications for Forms, Reports, & Screens
Narrative Overview Who will use it? What & when is the task performed?
Sample Design Testing and usability assessment
Can you complete the task efficiently? (time to learn, speed of performance, rate of errors, rate of retention)
Is the form/report accurate? (expectations, confidence)
Do you like using the form/report? (satisfaction)
Guidelines to Design Maintain consistency and standards Allow shortcuts and accelerator keys Provide feedback to user actions Provide logical sequencing & closure Report all errors & suggest solutions Allow for reversals of actions Make the user feel in control Provide simplicity and ease of use
