Usable Security using GOMS

E-Government websites have an overwhelming responsibility to ensure they are designed to accommodate the very citizens they serve in addition to providing equal and open access to all audiences given their diverse demographic demands. However, e-Government websites have not adequately addressed user-centric designs for social inclusion of citizens and lack a standardized approach to evaluate and compare the usability of user account interfaces to accommodate a diverse user population. This study proposed extending a goal driven usability evaluation methodology called GOMS with UML Use Cases by establishing common security goals called Security Cases. Security Cases can be used to standardize and objectively quantify and compare the task times and error count in completing similar goals on different websites. This study assessed if incorporating Security Cases with GOMS is a more effective way to quantify and compare different security interfaces when performing a usability study to determine more effective interface designs to accommodate a diverse population and encourage improvements in making user account interfaces more accessible to e-Citizens.
