Scoring system
For each heuristic, provide a score from 0-5. This provides an at-a-glance indication of the strengths and weaknesses of each element of the intranet. An overview of the scoring system is as follows:
0: Extremely poor, non-compliant with guidelines, or not implemented
1: Very poor, likely to cause significant problems for staff
2: Poor, likely to cause problems for staff
3: Good, but some aspects may cause problems for staff
4: Very good, staff should be able to use this feature easily
5: Excellent, very capable, delivers considerable benefits, meets (or exceeds) all of the criteria outlined
Note: in the rationale, details have only been provided for scores of 0 and 5. This has been done to provide a balance of sufficient detail, without making this document either too proscriptive or unwieldy to easily use in practice.
The reviewer must therefore evaluate each aspect of the intranet against these two extremes, and assess what the most suitable score is.
For example, a heuristic that meets almost all of the criteria, but misses out some small elements, should be given a high score (such as 3 or 4). Conversely, an element that provides some very limited capabilities that are better than nothing should be given a low score (such as 1 or 2).
Where capabilities are not provided at all by the intranet, a score of 0 should be given. For example, if there is no search on the intranet, all of the heuristics in section 3 should be given a zero score.
