Aspects to consider
Extracting Information How easy is it to get the information? What information can you get?
Memorizing InformationCan you memorize the information after reading? Is it easy to remember
ClarityIs the structure obvious to the user? (Naming, Positioning, Design of elements)
ComprehensibilityDoes the user understand the content?
Readability - Is the text easy to follow?
Look & Feel - How is the first impression? Do you have a good feeling reading the paper?

UX Research test scenarios
KP Ludwig John
It’s best to test with representatives of your main target group.But don’t be obsessed about it!If its difficult to recruit them, test with people you can get hold of. Take it in account when evaluating the test results:Would our users have that problem? Or was it only a problem because the participant wasn’t familiar with the field?
Rather few but frequentlystart early in the development processand repeat and repeat and repeat
Who do the test with?

The best results come from testing no more than 5 users and running as many small tests as you can afford.

UX Research test scenarios
KP Ludwig John
Most significant problems will be discovered by small number of test users already.
Finding three participants is easy to handle:test and debrief (Nachbesprechen) the same day! Design small tests with focussed tasks.Learn, move on and test again.

How many test persons?
Can you use the same participants again?Not for the same task or application.They know too much already. ?

Determine:
What do you want to find out?Which elements of the application are crucial?
Formulate the tasks straight forward, short and precise
Each task should have a defined goal(that defines, when the task is done)

!Start with simple, easy to handle tasks!More difficult (or more complex) tasks are possible,but not good at the very beginning of the test)

Test conductor although positioned next to the proband,remains silent / interferes only in critical situations.
Don’t get into conversations with the test person during the test itself. That can be done after the test.
Test scenario Content and style
Let the test person act rather independently and on its own

There will be 3 different PDFs which contain several information.
• You have to do some tasks, they will be displayed on the screen. Pressing space on the keyboard will start the first question,
• We would like to encourage you to tell us what you are thinking while doing the tasks. It helps us analyzing your final answers, but don’t feel forced to comment if you don’t feel like it.
• If there are no more questions from your side about the test procedure itself, you can start by pressing the SPACE key
• After a short calibration of the eye-tracking software the actual test is going to start immediately.

Test scenario
source: https://www.nngroup.com/articles/priming/
When tasks use terms already present in the interface, participants are primed by the task formulation and tend to look for those exact terms.
When asking people to search for an “iPad keypad.” Although the word “keypad” is not as frequent as “keyboard”, most users typed “keypad” instead of “keyboard” in the search box.
… the test may have yielded the wrong conclusion that the product was easy to find.

Test scenarioDuration
Rule of Thumb:Between 10 -30 minutes per person is OK
• less than 10 minutes seems rather short as well to the test person as for the team
• longer than 30 minutes requires a lot of effort from both sides
depends on test goal and circumstances
