PURE Usability Evaluation Method
PURE (Pragmatic Usability Rating by Experts) is a method to evaluate the usability of a workflow and identify opportunities for improvements. It's more lightweight than traditional usability testing, but still provides useful results. In this method, usability experts assign one or more quantitative ratings to a workflow based on a set of criteria and then combine all these ratings into a final score and easy-to-understand visual representation. For more details on the PURE method, please check out Nielsen Norman's page on the subject.
