Redefining Usability Heuristics for Transactional Web Applications

There are multiple methods that permit measuring a software product´s degree of usability. Heuristic evaluation is an inspection method widely used, since it allows finding many usability problems. Transactional websites have their own defining features, therefore general heuristics may not be appropriate when evaluating their usability. A set of usability heuristics has been developed for transactional applications. The paper presents its refinement, based on experimental validation.
