Steve Krug gives a presentation to a group of developers for Outsystems. Video and slides are available, along with Outsystems' short eBook on usability rules for developers.
As he has in the past, Steve makes a great case for simple, regular user testing and does a demo to show how easy it can be. The difference here compared to other videos freely available is the developer focus this time. He touches on agile development and Jeff Gothelf's Lean UX approach.
And the little eBook that accompanies the presentation provides a nice little idiot-sheet for those new to the discipline.
