DEBUG YOUR DESIGN FOR SERIES 40 FULL TOUCH

Overview • Before we start • Usability optimized • Test preparation • Test session • Test outcome • UX offering • Take home messages • Exercises



BEFORE WE START

Even your mom will give you more insights than nobody.


Be ready to dump the most precious thing you have – your code.


Learn to step back and observe.


Everything else is simple – it is!



USABILITY OPTIMIZED

Usability is an analysis how to reach a goal.


Old-school usability studies are usually not suitable for small software houses.


You want to improve – not prove.


Test early. Test often. Fail fast. Fail cheap.


2-3 participants are enough if you test multiple times.


As a test facilitator you must have a neutral attitude and be eager to learn.


Facilitator presents tasks. Observers observe. It’s that simple.



TEST PREPARATION

Get yourself a checklist for the entire test and a timetable for the sessions.


Write down all the tasks and create stories from them.


Invite from the target audience if you can – but do not get stuck with it.


Do not use previous participants in the same project again.


Get rooms, snacks and beverages for the test.


You might need help to run the show.


Prepare the prototype.


Put participant's tasks on index card and print all your tasks on paper.


Run a pilot study.



TEST SESSION

Test for 1 hour.


• 10 min: Welcome, introduction, sign agreement and warm-up • 30 min: Tasks • 10 min: Open issues, wrapping up and good-bye • 10 min: Take additional notes and prepare the next session

The participant talks – not you.


Present each story and task on an index card; one after another.


You must understand what people do and what people say.


Ask for open issues after the tasks are done.


Reward your participants.



TEST OUTCOME

The biggest issue is the most urgent.


Concept – redesign. Implemented app – try to tweak only.


Test your tweak – a very simple test might do the trick here.

TAKE HOME MESSAGES

Even your mom will give you more insights than nobody.


2-3 participants are enough if you test multiple times.


Run a pilot study.


The biggest issue is the most urgent.



EXERCISES

Exercise: Watch the videos. What went wrong? How do you fix it?


Exercise: In which case is it enough to have only 2-3 participants and why?


Exercise: You are not sure what the participant is thinking. What do you do?


Exercise: The participant mentions that she is not giving you what you expect from her. What do you say?


Exercise: The participant thinks she is doing everything wrong. What do you say?


Exercise: Why not giving all the tasks on paper to the participant?


Exercise: How would you classify the errors you find? Which errors do you fix first?
