It's really interesting to read about the range of recommendations made and the ways in which the work was reported. The authors draw some useful conclusions about what makes a useful, accessible and most importantly of all, actionable usability report.
The study finds that only 14 of the 84 studied comments (17%) addressing six usability problems contained recommendations that were both useful and usable. Fourteen recommendations were not useful at all. Sixteen recommendations were not usable at all.Making Usability Recommendations Useful and Usable - PDF download of a report by Rolf Molich, Robin Jeffries and Joseph Dumas for the Journal of Usability Studies
