PUBLIC MARKS with tags evaluation & overview

Most people that carry out usability expert reviews use Jakob Nielsen's ten usability 'heuristics'. Many of these guidelines are common sense but they are not based on substantive research. The International usability standard, BS EN-ISO 9241-110 proposes an alternative set of seven guidelines. These guidelines have the benefit of international consensus and they can be applied to any interactive system.

Heuristic evaluations are arguably most valuable as an early evaluation technique, performed on an exisiting system or first prototype in an effort to identify the major usability problems.
