NOTE: This poster won the first prize in the Poster Competition at the ZAW3 conference. The aim of this research project was to determine the degree of usability of Cape Town hotel online reservation systems. The literature has shown that the main aim of website usability is to make the engagement process with a website a more efficient and enjoyable experience. Researchers note that good content, simple design and few grammatical errors are required to establish a website’s trust and users tend to trust websites that are more usable. It has been proven that poor website design results in a loss of potential sales due to users being unable to find what they want and a loss of potential repeat visits due to an initial negative experience. The research instrument that was employed in this research is usability testing. It is an approach to product development that incorporates direct user feedback throughout the development cycle in order to reduce costs and create products and tools that meet user needs. The research focussed on Web-based reservation systems and only the usability was measured. In this research project, both standard approaches in user testing were used in a quantitative and qualitative research approach. In conclusion, the outcomes of this study indicated interesting patterns in that reservation systems met user requirements more often than expected. The amount of time spent to complete a booking also decreased as users worked on more than one reservation systems.
