Unformatted text preview: tal case, the tasks are structured using 25 common menus starting from “World, U.S, Weather, Business, Sports, Law, video, Travel…up to contact us”. It guides the user how and where to begin with the portal. The user can easily complete basic and common tasks with the minimum amount of interaction. Therefore, the CNN portal fits with the theory of structure tasks. Learnability According to Nielsen (1993) the system should be easy to learn so that the user can rapidly start getting some work done with the system. Various tasks were designed to test learnability of CNN WAP portal. For instance, task 6 from CNN portal “Go to Video menu and watch any video clip of your own interest” was typically designed to test the learnability factor. The users validated the ease of learnability by confidently moving around the portal and successfully completing the tasks. In few minutes, they become familiar with the portal. Therefore, CNN portal fits with the theory of learnability. Efficiency of Use According to Nielsen (1993) to ensure a high level of productivity, the systems should be efficient to use, so that once the user has learned the system they can easily use it. System efficiency refers to the stable performance stage of expert user. In CNN case, it was observed that the portal provides high level of efficiency of use, since within a very short period of time; the users were successful and confident to conduct a variety of tasks. While completing tasks 1 – 8, users easily navigate within the system and reported that the portal is efficient; therefore it fits with the theory. 69 Memorability According to Nielsen (1993) memorability is referred that a system should be easy to remember, so that a formal user is able to return to the system after some period without having to relearn everything over again. The CNN portal found easy to memorize. For instance, in task 6 “Go to Video menu and watch any video clip of your own interest and go back to home page”, the users were involved in various steps, however they easily manage to complete that task and at the end of the task 1- 8, mostly users feel that they are now expert users. Therefore, CNN portal align with the theory. Subjective Satisfaction According to Nielsen (1993) subjective satisfaction refers to the extent the system is pleasurable to use. User likeness is critical for system success; therefore the system should be pleasant to use to achieve subjective satisfaction. Since, the subjective satisfaction is an important usability attribute for the systems that are used on an optional basis in a non-work environment such as computing games, interactive fiction and creative painting. In order to validate subjective satisfaction, the 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, search sport sore of any game / watch any sports video” were designed. The users successfully carried out the tasks and reported them operational. In addition, the users were successfully able to move around the system easily and no major errors were observed, therefore both WAP portals agree with the theory of subjective satisfaction. E-Navigation and Labeling Ramsay (2001) reveals that E-Navigation and Labeling are two major issues. In contrast, the networks and content providers offered broad lists of sites and services by proving that everything a WAP user may need, however, for the users this is a recipe for disaster. The long manus required thumb-numbing and scrolling. Categories are good way to sort information. In CNN case, it is observed that most of the information available on CNN portal is organized by making various categories. For instance, all the world news are covered under “World” link, all of the travel related news and deals are covered under “Travel” and all law related articles and upcoming under “Law” therefore all the information is organized using different categories. The CNN portal fully supports the theory. Unnecessary browse time According to Ramsay (2001) time is big money on WAP. Any portal that is easy to browse and presents its information clearly is one that the users will like to return again 70 and again. Generally all major WAP portals took unnecessary time to browse and display information. In case of Task-5, under link, there were almost 9 different big and small images found which noticeably reduced the down loading time, Therefore CNN does not fully supports the theory. Minimize input According to Ramsay (2001) WAP sites should be designed in a way to minimize user input. In order to fix this issue, WAP products should be offered as preset choices, so that user just needs to browse and select the required information. In CNN case of Task8, the sports highlight shows a broad range of sport highlights including sports scores. In order to find any particular sports info, the user has to write the sports name in “Search Box” to...
