My organisation is giving some time to thinking about how we develop attitudes towards UCD, usability and a user experience focus within the company. While we're doing lots of stuff at "ground-level" and there is lots of executive support, we're looking to reach out to the many developers, testers, analysts and managers involved in software development.
One of the things we're thinking of is getting an inspriational speaker in from outside, who can really persuade and motivate our people - perhaps reinforcing the belief in UCD and a design-focus for those who have it, and giving those who are not so convinced some pause for thought and reconsideration.
So, I was wondering whether anyone had any recommendations for a speaker who they have found inspirational motivational, or who they have seen achieve this speaking to a largely technical audience? All input gratefully received!
