Usability and Functionality Evaluation of the Most Profitable Croatian Companies’ Web Sites

The most commonly used form of Internet presence for a company is its official web site. Business web sites have been used since the beginning of Internet development in its early stages. As the Web space has been changing over time in quality, quantity and capabilities, so have its business web sites as well. It is a known fact that web site quality varies as well as its usability and functionality. Having that in mind, there is an obvious need to systematically analyze and evaluate business oriented web sites. Both theoreticians and practitioners agree on the basic evaluation components of web site analysis in general. However, there is no single widely accepted performance evaluation model of business web sites. The aim of the paper is to analyze and evaluate web sites of 190 most profitable Croatian companies in different economic sections (sectors). The paper is focused on web site usability and functionality from the user perspective. Usability and functionality is measured in order to compare business web sites and assess their performance.
