Evaluation of User Interface Usability of Public Administration Webpages by Models

This article presents a not well-known way of usability evaluation and it focuses on user interface evaluation using models. It is another method of evaluating, apart from user and the expert evaluation. This article presents a short review of the existing models and it is focused on usability evaluation. There are seven basic models. Some of them are demanding because of their time requirements; other because of their knowledge demands; or there is a combination of both factors. Based on the models review and comparison, one model was chosen for a statutory cities websites evaluation. Before the model was constructed, there was an existing agreement that one model was to be created - for each city and for each task. There are five chosen statutory towns (Brno, Hradec Kralove, Olomouc, Pardubice and Plzen) and five chosen tasks - that means twenty-five models were created in the end. For each model, time of its performance was stated. Thanks to this factor, the statutory city Hradec Kralove emerged as the town with the best usability. This result was approved by usage of a supplementary method.
