Design Process
Don’t design for yourself.

Usability
The effectiveness, efficiency, and satisfaction with which specified users achieve specified goals in particular environments !
This does not mean you have to create a “dry” design or something that is only good for novices – it all depends on your goals
Vuistregels
Hoe weet je dat een UI “goed” is?
The economist – oct. 2004

To be truly successful, a complex technology needs to “disappear”
The real test is always the mom test
You are not the user! !
(if you are the developer)
Know your users...
Study their workflow & Habits
Users cannot tell you what they need (Steve Jobs)
Study behaviour not opinions
Don’t ask for opinions
Know your users...
“logical analysis is not a good way to predict people's behavior (nor are focus groups or surveys): observation is the key” !
“I caution that the time frame for adoption of new technologies is measured in decades, not the months everyone would prefer” Donald A. Norman
If the user does something “wrong”, it is the fault of the system designer!
ALWAYS RIGHT
Usefulness! Usefulness! Usefulness!
Four MythsOnly experts create good designsÄ experts faster, simple and effective techniques anyone can apply
We can fix the user interface at the end Ä good design is more than just user interface Ä having right features, building those features right
Good design takes too long / costs too much Ä simple and effective techniques can reduce total development time & cost (finds problems early on)
Good design is just cool graphics Ä graphics part of bigger picture of what to communicate & how
