Is the site design clear and transparent? 1
The homepage is uncluttered but the small font size of the main menu lets it down. The menu headings may not be clearly understood by users. Knowledge of who CRD is, is required to use this site best.
Is the site design consistent from one page to another? 2
The design is mostly consistent except that the font size changes quite a bit from readable to unreadable!
Can users find what they need on the site? 1
It is possible to browse CRD's publications by topic, although a health topic menu on the homepage would be better. There is a search box, results are displayed reasonable well, but it is unclear how they are ranked. Users need to know to search the databases separately to find additional relevant information for prostate cancer. Prostate cancer doesn't appear in their site map either.
Is the format of information clear and appropriate for the audience? 3
Record is a cost study.
Weighted total (Usability + (Reliability x 2)): 38
