A Heuristic Evaluation, or Usability Audit, is an evaluation of an interface by one or more Human Factors experts. Evaluators measure the usability, efficiency, and effectiveness of the interface based on 10 usability heuristics originally defined by Jakob Nielsen in 1994. Nielsen’s Usability Heuristics, which have continued to evolve in response to user research and new devices, include:

A contextual task analysis, or contextual inquiry, is a user research method that applies ethnographic observation and one-on-one interviewing to understand the task procedures that users follow to reach their goals. The researcher silently observes the user at work in his or her natural work environment and notes any tools and people that support the user as they work toward task goals.

Card sorting is a useful tool to determine how users categorize the information that will appear on a website. The name “card sort” comes from the original exercise, which used index cards with a word or phrase written on one side, and in some cases, a definition or additional information on the reverse side. There are traditionally two types of card sort exercises used: open card sort, and closed card sort.
