Evaluation: heuristic analysis

Heuristic analysis provides a way of objectively evaluating your own work or that of others against a set of design principles (“heuristics”). While it is a great way to pick up issues early on, it is not a replacement for observing real people using your system. We’ll get to usability testing later on!

A quick overview

Heuristic analysis is something we’ve used sporadically in the past at the EBI, in different projects, and I blogged about using heuristics and other design principles (notably CRAP) a while ago. More recently, though, as part of a recent drive to begin looking at the design and delivery of the tools that the EBI provides, we have been able to begin to introduce evaluation according to heuristics as a more common activity across project teams at the EBI.

Heuristics – a fancy word for principles or guidelines – offer a very useful framework for objectively evaluating, for example, a data visualisation tool, particularly in terms of usability. Importantly, this does not and should not replace the observation of real users carrying out real tasks with a tool, as I wrote above, but it can give you a way to catch usability issues cheaply before using time and resources to run usability tests.

While we begin to develop a more institute-wide approach to using heuristics at the EBI, we are working with a customised version of the heuristics developed by Rolf Molich and Jakob Nielsen – basically a big checklist.

Perhaps the first thing I ever read about heuristic evaluation was on Usability Net, and I’d say that it still holds strong! That description references Jakob Nielsen’s article “How to conduct a heuristic analysis“.

The heuristics checklist we use at the EBI is a customised version of the System Checklist developed by Xerox. You could try that. I also like the “dev_hr.doc” (a Word doc you can download from the Usability Toolkit) way of approaching this, although trials with developers at the EBI suggested they weren’t so keen!
