There is a conflict of interest in the world of software development because the people who build it are also the people who design it.If carpenters designed houses, they would certainly be easier or more interesting to build, but not necessarily better to live in. The architect, besides being trained in the art of what works and what doesn't, is an advocate for the client, for the user.

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

The economist – oct. 2004

http://www.economist.com/displaystory.cfm?story_id=3307363

To be truly successful, a complex technology needs to “disappear”

The real test is always the mom test

23

You are not the user!

(if you are the developer)

24

Four Myths

Only experts create good designs experts faster, simple and effective techniques anyone can apply

We can fix the user interface at the end good design is more than just user interface having right features, building those features right

Good design takes too long / costs too much simple and effective techniques can reduce total development time & cost (finds problems early on)

Good design is just cool graphics graphics part of bigger picture of what to communicate & how

25

If the user does something “wrong”, it is the fault of the

system designer!

26

“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”
