I like to look at feedback as a way to improve people as well, because people that improve continuously are more likely to produce better software in teams. Anyways, the slides for talk are on Slideshare and you can download them from there. I've tried to design my slides so they're self-explanatory to some extent. I'm happy to answer questions if you have any.
During the webinar, I also shared an elearning module on Feedback, which you can find here. Hopefully, this could be useful for any team to develop a healthy practice of sharing feedback. Let me know what you think.
This apart, chat transcripts and a webinar recording will soon be available at the ThoughtWorks Studios community, if they aren't there already.
