Usability, accessibility and security are some of the properties that constitute the quality of a website. High level of quality can only be achieved if proper organization, work processes and tools for usability and accessibility are deployed. Open research issues Im working on include proper understanding of effectiveness of automatic tools for testing accessibility, appropriate merging of automatic and manual assessment methods for accessibility and usability, how to measure accessibility.
