Heuristic Evaluation

Basic steps

1. Gather several evaluators (3-4 is good)
2. Determine users and context
3. Team members apply heuristics independently
4. Consolidate and prioritize findings

Summary of heuristics

This updated list is presented in Usability Evaluation Methods (1994), chapter 2 by Jakob Nielsen. A summary of the process and an older list of heuristics are presented in Lewis and Rieman.

The list of heuristics was derived from factor analysis of actual problems. The methodology and explanation is presented in Nielsen's 1994 CHI paper.

• Visability of system status
• Match between system and real world
• User control and freedom
• Consistency and standards
• Error prevention
• Recognition rather than recall
• Flexibility and efficiency of use
• Aesthetic and minimalist design
• Help with errors
• Provide help (if needed)

Discussion points

• Why evaluate independently?
• Value of 3-4 inspection experts
• Useful descriptions of users and contexts
• Which usability objectives do these heuristics address?
• Tradeoffs among competing heuristics and goals. Discuss difference between Minimal CTA Map and Detailed CTA Map
