Usability Test
Usability testing involves measuring real-life scenario performance by having participants go through predefined tasks. This process helps in analyzing the efficiency of software and allows testers to log performance. Preparing for a usability test includes defining tasks, selecting suitable technology, and identifying participants. Tasks should reflect real-life scenarios to cover major functions, considering participants' psychological factors to design tasks accordingly. Technology requirements include tracking participants' time on each page, their path to solutions, and enabling tasks to be reshown at their will. The number and type of participants, such as Jakob Nielsen, are essential for conducting effective usability tests. Results are measured based on task completion rates, providing valuable insights for improvement.

Usability Test Alban Demiraj
What is the Usability Test Measuring real-life-scenario performance Participants go through the predefined scenario The Software and the testers log the performance
Preparing the Test 1. The Tasks 2. The Technology 3. The Participants
The Tasks - Requirements To run a Usability Test we need some real life scenario (tasks) the participants have to complete. Our result will very according to the capability of this tasks to cover major function. We have to consider participants psychologically in order to get their best Design tasks accordingly Order tasks accordingly
The Tasks Find the article "India's surprising economic miracle". (The Economist US, 2 Oct 2010) See how easy is for the students, to use AUP s subscription to external resources. Find the books from William Shakespeare. And open the 3d on the list. Analyzing the efficiency of the Libraries Search Engine. Find when you can access the library building. Analyzing the load of links in the Library s main page. Find how to use the Academic Film Collections. Analyzing the naming of links in the Library s pages. Find a book on "Cognitive Science" and "Computer", published between 1950 and 2000. Analyzing how easy is to find and use the Advanced Search Engine.
The Technology - Requirements Keep track of the time participants spend on each page Keep track of the path the participants travel to the solution Be able for the participants trough the software to identify their finish Be able to reshow the task to the participants at their will, anytime

Discussing Task Goal Conclusion Find the article "India's surprising economic miracle". (The Economist US, 2 Oct 2010) See how easy is for students, to use AUP s subscription to external resources. One possible explanation for this difficulty is that students find it very difficult to adapt to different external resources interface, thus loosing time there Find the books from William Shakespeare. And open the 3d on the list. Analyzing the efficiency of the library search engine. Students consistently use the keyword search, even on occasion when other types of searches would be much more efficient. On explanation for this behavior is that students are used to Web search-engines queries (such as Google Searches), and they don t see the utility of index-specific searches.
Discussing Task Goal Conclusion Find when you can access the library building. Analyzing the load of links in the libraries main page. The AUP Library homepage is overloaded for students eyes. They offer direct link to tons of information, shadowing basic info like the library hours. All + Find how to use the Academic Film Collections. Analyzing the naming of the links in the library s homepage. The AUP Library homepage is well named; still students seem to somehow tend to look for the natural Google instinct they own. Find a book on "Cognitive Science" and "Computer", published between 1950 and 2000. Analyzing how easy it is to use the Advanced Search Engine. The majority of students don t know what the Advanced Search is. There is no link from the home page to the Advanced Search, one must run a search in order to be able to use the advanced search.
