  • He treats learnability as the most fundamental criteria. The system should be easy to learn so that the user can rapidly start getting some work done with it”
  • “Jeng proposed a usability model for academic digital libraries employing four operational usability criteria – effectiveness, efficiency, satisfaction, and learnability”
  • Guenther explains usability as users’ ability to perform the tasks with ease when users use and navigate the Web site. In order to decide what is “usable”, criteria and measurement of usability are developed but these evaluation criteria should be different based on the purpose of Web site and the type of organization. He gives examples of the criteria of testing usability of the web site of a financial company should be different with those of a website addressing consumer health. The criteria for the former one should be designed to test the ability of enabling financial transactions while those of the latter one should be designed to provide health information
  • There are many different components that can potentially contribute to a user’s online experience and hence the web usability of a website. Not all the literatures agrees on exactly what components or criteria best describe or judge what makes good web usability but there are some agreed upon elements. These are as follows:
  • E.g. a student with specific information needs will have their online experience affected more if information content was lacking on the website compared to having slower download speeds. Personal context can also play a major role in web usability criteria as well. People more familiar with similar websites will be able to use like websites more easily than people who don’t. With this in mind it is important to base web usability criteria around your user’s contexts.

    6. 6.  A usability model for academic digital libraries -four operational usability criteria effectiveness efficiency satisfaction  learnability Jeng (as cited in Soohyung & Jee Yeon, 2011, p. 525)

    22. 22.  Web 2.0 as an emerging pattern of new uses of the web and approaches to web development . OReilly (2007)“ To transform the Web into a space that allows anyone to create and share information online-a space for collaboration, conversation, and interaction; a space that is highly dynamic, flexible, and adaptable.” Coombs (2007, p. 16)
