System and User Environment Design
•    The Apple system success is due to system engineering, the device can only get better, smaller and with more capacity, in the future the hard disk be substituted by a flash drive, simplifying the system itself.

•    Sony to compete, must propose a better system, not a lower capacity one..
System and User Environment design
•    The same can be said about written media, books, magazines etc. Sony by proposing its reader may be successful but again the entire system must be in place, the reader, really portable and efficient with enough

•    When the winning idea is a system, the final design look, while important, is not determinant.

Lets try to define UX …
•    A look at many UX models

–    UX elements
–    UX honeycomb
–    UX forces
–    UX umbrella

The famous “UX elements” model



The now famous model



Opposition to jesse’s model
•    This puts me in direct opposition with Jesse's diagram. Those aren't elements of user experience. Those are elements of web design.


•     Performing those elements well should lead to offering users a quality experience, yes. But "information architecture," "interaction design," "user needs," etc. etc. don't comprise the user experience.


•    A quality user experience is comprised of things like desirability, usability, enjoyability, utility, delight, satisfaction, etc. etc.


Improving the model



The Forces/ Relationships



The old favorite
