There are two major uses for heuristics in general.
- As a list of qualifications used in a score-based review of a site.
- A list of categorized statements by industry experts used in a qualitative evaluation of a site.
The former we see as a Heuristic Review. Where on every page, one would ask a set of questions based on a set of proven or broadly accepted heuristics as a review methodology. The goal would then be to rate each question on a 3pt scale and then map each sections score on radar diagram or prioritize them like one might prioritize bugs. There are a lot of great resources on this process an example can be found here.
The latter, in the list above, is how we see The Heuristics within this site being used. The idea is that as UX practitioner, you would review a site and see major issues. You would then make recommendations on those major issues, and use The Heuristics as a way to validate your recommendations. We see this as a faster way to address major issues in a site vs. an exhaustive review of an entire site. It also forces a more rigorous approach as opposed to simply opining, and often points the way towards a solution.
