IT302_Unit_4_Discussion_1.docx  Professor and Classmates,  ï‚·Heuristic Evaluation – This is a usability engineering method to determine the usability problems in a user interface design (Nielsen, 1994). This method involves having evaluators examine the user interface and decide if it complies with established usability principles. The evaluation is done by each evaluator performing the examination of the interface alone. Once all evaluators have completed their examination of the interface, they get together and gather all the findings into one final report. 10 important rules for Heuristic Evaluation:   1.Visibility of System Status   2.Match Between System and Real World   3.User Control and freedom   4.Consistency and Standards   5.Error Preventions   6.Recognition rather than Recall   7.Flexibility and Efficiency of Use   8.Aesthetic and Minimalistic Design   9.Help User Recognize, Diagnose and Recover from Errors   10.Documentation   Pros and Cons of Heuristic Evaluation:  oPro –   ï‚§Done early in the usability engineering lifecycle  Very detailed assessment based on clear criteria  Different people find different problems – This benefits the use of multiple evaluators   ï‚§Evaluators generally go through the interface twice. Once to familiarize themselves with the flow of the interface and the second time to focus on specific elements of the interface.   oCon –   ï‚§Difficult for a single user to find all the issues
