Summary Table

Compilation of problems and ratings

The following table lists all of the violations identified in the individual heuristic evaluations, and shows how they were combined.

For each violation, the problem number, violated guideline number(s), and severity rating as initially identified by each evaluator are shown (LD = Linda Duffy, JAF = Jean-Anne Fitzpatrick, SKJ = Sonia Klemperer-Johnson, JR = James Reffell). When a particular violation was not identified by a specific evaluator, the cell does not contain a number.

In addition to the individual severity ratings, the severity rating agreed on by the group of evaluators is shown in the column labeled "Final".

Note that some violations were determined to be limitations of the prototype, rather than design issues, based on the documentation provided by the designers. These violations were assigned a final severity rating of zero. In a few cases, violations were determined to be equivalent to previous items. In these cases, no severity rating is given and the violation is not included in the summary statistics.

For reference, the individual heuristic evaluations on which this compilation is based are available in MS word format.
