Temporarily Unbroken: Learning about Failure Before it Happens

"Every glass is temporarily unbroken" and all software has issues. Teams need to value engaging deeply with the how the tools and systems we build can fail, how to reduce the likelihood of that failure, and to make it more manageable when it does fail.

This talk introduces the "Temporarily Unbroken" mindset, how it can be used to transform the way we talk about the things we build, build them better, and support ourselves in the future.
