Changing Legacy code, and legacy organisations, is complex and takes software craftsmanship and software engineering skills.

In this episode, Dave Farley explores how to introduce Continuous Delivery to such organisations with lots of tips and advice on addressing some of the commonest technical barriers to improving automated testing, configuration-management and enabling much more frequent, reliable, releases.
