Jez Humble is back and building a lean enterprise! Carl and Richard talk to Jez about continuous delivery and all that amazing DevOps stuff - but then we get to the serious bit, which is really about how DevOps is a manifestation of organizational change. You need buy-in from the top to make it happen, but it can't happen all at once. How do you make gradual improvements to present the power of a better culture with deeper understanding? Jez talks about the importance of metrics and measuring the performance of your software. And in the end, the best metrics are the ones that relate to the business - which is a great way to talk to management!
