Expert Usability Review

The review is conducted by a small band of usability experts who examine the service or product to identify any possible usability issues. Expert Usability Review belongs to the few means within the user process that doesnt include any contact with the end users.

The modern literature review on this mean refers to the formal way of Heuristic Evaluation that alludes to experts observing graphical user interface for devotion to usual usability guidelines.

While Heuristic Evaluation is a usual mean used in formal or academic surroundings, it could be debated that this mean is too tough and usually fails to meet the customers needs. Evaluating an interface by checking boxes to define where it meet or not so called usability guidelines doesnt put enough value on the uses context, or the targets of the system. The process of evaluation relies upon usability guidelines that and the researchs result on graphical user interfaces that may be entirely dissimilar to the one being observed.

Some guidelines are meaning, but while stuck to by letter, they may lead to bad usability decisions for the designer doesnt take into account the specific users, context used for the system, and the targets of the service or product. Following guidelines can be tricking and can provide a deceitful sense of security that the interface is usable, when its not.
