Web usability is the simplicity of use of a website or a collection of web pages where web design is considered a general paradigm(Huber and Vitouch, 2008)
This is a quality aspect that evaluates how easy web defined user interfaces are easy to use.
Web usability is defined by the following quality components;(Frederick and Lal, 2009)
The efficiency of using the website or web page to accomplish basic tasks during the first time of use
The easiness of performing various tasks once the user has learned how to use the web page or website
This is the ability of users to recall the step by step process of accessing the website and performing a range of tasks after not accessing the page in a long period of time
It determines the probability of users to make erroneous mistakes and the ease of recoverability from the mistakes
The ability of the given website to give satisfaction to the user after using it therefore, the usability should be pleasant to its users
It defines the functionality of the website, its ability to perform activities smoothly with efficiency as expected by the user
INFLUENCE IN WEB DEVELOPMENT
Examine how the website usability elements;
1. Graphical attractiveness
5. Ease of use
Drive users' attitudes and intentions toward the website and how these effects vary according to site experience and end product tangibility.(Arriba and Brugos, 2002)
Results show that while the effects of site interactivity and graphical attractiveness were more influential for services sites, the effects of site information and trust were stronger for tangibles sites. Alternatively, compared to returning site visitors, first-time visitors perceived the website as less easy to use, needed more time to accomplish the online task, and based positive attitudes and intentions more strongly on the site information and interactivity. The results of a second study performed in a proximate culture largely corroborate these findings.(Aljukhadar and Senecal, 2009)
The web developers are redesigning website Usability over the times to suit the user requirements.
Usability comes in handy when the web developers endeavor to come up with web based applications that can run in mobile devices which is easily accessible to users rather than computers(Soufi and Maguire, 2007)
Many previous studies reveal that cultures not only affect web design, but also impact web usability test. Most previous cross cultural web usability research adopted a western usability method to collect data from users, however some researchers have recognized that there is a need to define usability by considering in cultural context . The traditional usability method is not a properly way to investigate people from different cultures. New usability methods are required to be developed to completely understand users from different cultures.(Hsieh, 2011)
