In Second place, in task-7, In order to book a ticket under the link the external link for Air Canada does not work and system generates following error message “This site is temporarily down for maintenance. Please come back later. Thanks, Sorry for inconvenience” As for as, the error message was concern, it was sensible and supports the theory. Robustness According to Dix et al., (1993) a user engaged with a computer in order to achieve some goals in that specific business domain. The robustness of that interaction comprises features that support the successful achievement and assessment of that goal. In order to validate robustness in CNN portal, various tasks were conducted. Especially task-7 “Go to Travel menu, and choose a travel plan of your own choice” and task-8 “Go to sports menu, under sports highlights, watch any sports video” were performed. The task-7 was partially successful, since the user were unable to perform any travel arrangement using Air Canada external, however they successfully perform booking using other external air lines. In task-8, the users attempt to find “Score” of different sports such as ice-hockey, soccer, volleyball etc. In order to find any sports score, user has to enter the sports name in “Search Box” to retrieve desired information. While writing sports name, the users sometime could not got results because of space in keywords and sometimes joining the keywords. The users were confused how to proceed with the task. In addition, in case of error in spelling or space in keyword, system does not produce any “ALTERNATIVE”, (Did you mean: Ice Hockey) that could be the best way to guide the user, rather than not showing any result. Since, the robustness of CNN was very poor therefore it does not support the theory. 80 System utility According to Preece et al.,(1995) the term ‘utility’ refers to the functionality of a system or system efforts to improve ‘effectiveness’ and ‘efficiency’ which are clear and fundamental aims.

The portal is fully operational to perform all basic tasks successfully and supports the theory.

The information was mainly managed using different product segments such as Books, Electronics, DVD’s etc. However, user can find variety of products using “Search” option. Whenever search was made the system immediately shows the result or shows a message “Processing data”, therefore user should not click the button again and again. In “Shopping Cart” user can view all added products. “Shopping cart” also shows the data without any delay.
