video” none of the video’s were operational, however in this case system does not
produce any error. In Second place, in task-7, In order to book a ticket under the
cnn.com/Travel 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
As for as, the error message was concern, it was sensible and supports the theory.
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. System utility enables a system to manage and control system
operation so that application software can perform a task successfully. As for as, the
system utility of CNN portal is concern, the portal offers functional efficiency to
perform variety of tasks such as reading latest world news, weather, law, entertainment
Travel and health news and articles just a few to mention. The portal is fully operational
to perform all basic tasks successfully and supports the theory.
According to Preece et al.,(1995) the term ‘safety’ refers to its relation to computer
systems which is a principal importance in the design of safety critical systems.
CNN.com is a news providing agency, therefore based on their business nature, there
are no heavy transitions involved in CNN portal. Most of information is available to
readers free of charge. However, few articles need to be pay, in order to read that
articles. In such cases, the system can perform immediate transition using secure credit
cards, therefore it supports the theory. RQ 2. How the m-commerce interface design can be made
user-friendly? 6.1.4 AMAZON.COM Visibility of system status
According to Nielsen (1990) the system should always keep users informed about what
is going on through appropriate feedback within reasonable time. The user needs some
sort of feedback that lets them know that their command is being processed. The system
visibility of Amazon was very good. The system processes the request quickly. 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. In task-13 and task-14 visibility of system status was
experienced while using “shopping cart”, therefore Amazon supports the theory. 81 Use user’s own language
According to Nielsen (1990) the system should speak the user’s language, with words,
phrases and concepts familiar to the user, rather than system-oriented expressions. As
for as, the Amazon business is concern it offers verity of products to general customers.
Therefore, the language used in Amazon must be simple and easy to understand. In
task-12 “Find the latest deals under “Deal of the day” and explore the product
details”. Under that link, users found “Life span Fitness TR 3000-HRC Treadmill” as
deal of the day. When users attempt to explore “Product Details” information, they
found following information
“Sports, Life span Fitness amazon.com Sales Rank: 23, UPC: 0855959000201)”
The users reported the above mention information insufficient and inappropriate, since
detail does not give the right idea about product itself; it...
