scenarios

Recommended books on persona and scenario creation

The title says it all really ; )

I read a few threads on IxDA about the process of creating personas and using a modelling / plotting method to understand competencies etc, and I was wondering if anyone could recommend any "excellent" books on this topic.

Also, any recommendations on books for creating scenarios as a follow on process would be helpful as I'm looking for some linkage tools and processes in this area e.g. Research > Personas > Scenarios > Metal Models

Many thanks,

Chris

Do you ask for Functions or Scenarios?

Before testing: If you want a product with good UX, do you give the
programmers a list of functions or a list of scenarios?

Usually people write a functional spec for a software/website they want,
which they then give to the programmer. The programmer will create a
program/website with the functions you requested. The programmer comes back
and feels great about this product he created for you, with all the
functions you asked for, maybe even threw in a few extra.

You try the program and it has all the functions, but it is impractical.
