Sensible error messages
As for as, Amazon portal is concern, no error was reported. The users carried out task 914 without any major difficulty.
In order to validate robustness in Amazon portal, task-13 “Find GPS under Electronics
category and add to “Shopping Cart” to test a complete transaction” and Task-14
“Search any Microsoft product in software category and add into shopping cart” were
analyzed. The objective of these tasks was to test the full business life cycle of
Amazon.com portal. Both tasks were conducted successfully by using full features of
the portal, such as “Product Search”, browse “product information”, add product into
“shopping cart” up to payment. The response time was good. In case of spelling mistake
in search, the user was guided with an “alternative”. Overall, Amazon portal is a good
example of robustness.
Amazon portal found fully operational and functional. Users conducted multiple tasks
without any hurdle and without any major difficulty. Users validated portal’s utility by
testing full business life cycle of Amazon. No major error reported in portal that
prevents the customer to carry out basic tasks.
Amazon is an online retail portal that provides variety of products to their valuable
customers. The Amazon business nature is B2C. The customer can add products in
“shopping cart” as much as he/she wish. In order to proceed with payment customer
need to choose “proceed to checkout”. Amazon offers two options to choose and sign
in, 1) I am a new customer. 2) I am returning customer. “Sign in for using our secure
server”. In order to finalize the payment, customer will provide credit card information.
Amazon’s payment method and web server are highly secure. Amazon portal fulfills all
security measure to provide high level of system safety. 65 CHAPTER 6. DATA ANALYSIS In this chapter data will be analyzed and presented according to the mentioned
methodology. At first, within-case analysis of two case studies will be presented, in
which each of the two cases will be compared with theories. Secondly, cross-case
analysis will be performed to compare and analyze the two cases together. RQ. 1 Does the design of current WAP services contain
major usability flaws? 6.1 Within Case Analysis 6.1.1 Within Case Analysis – CNN Make careful use of graphics
According to Condos et al. (2002), the use of graphics should be done very carefully,
although some graphics such as corporate logo can represent a company brand or it can
differentiate a WAP site from competitors, however it should look pleasant to the eyes
of users and it should not occupy screen real estate which can be to present some other
material. In CNN case, we found that CNN.com portal contains high graphics and
images, which took more time to down load pages. Specially, in task 2, the link
CNN.com/LAW contains almost 9 different big and small images that noticeably reduce
the down loading time. Therefore, it does not support the theory.
Avoid long list
According to Condos et al. (2002) it is a well-documented fact that there are some users
who rarely scroll down a navigation page to see any options that might not be directly
visible to them. That is not mainly due to the fact that users are too lazy to scroll down,
but because they are not aware of the fact that there are more options available to them.
Therefore, designers of WAP services should generally avoid long lists when possible.
It is observed that the CNN.com portal have a very long list which take time in
downloading as well as take long time to scroll down. Furthermore, we found there was
approx. 25 common menus starting from “World, U.S, Weather, Business, Sports, Law,
video…up to contact us” which appears constantly under every links on every page. It
creates a scrolling hurdle for readers because on every page, in order to access the
desired information readers first have to scroll down all these common menus and than
he can access his desired information/article. Therefore it does not support the theory. 66 Make important options visible to the users
According to Condos et al. (2002), in order to successfully complete a task the
important menus or link should be directly visible to the users. In CNN portal all the
important menus were highlighted and easily visible to the customers such as “World,
U.S, Weather, Business, Sports, Law, video, Travel etc. The users can find further
information by clicking on any of these links, therefore CNN portal fits with the theory.
Provide clear, helpful and meaningful error messages
According to Condos et al. (2002), the designers of WAP services should make sure
that when an error does occur, the user is presented with a meaningful and, more
importantly, helpful message. In CNN.com portal case, under cnn.com/VIDEO menu
link, none of videos were operational. While, clicking on a...
