DESCRIPTION
This presentation focusses on the challenges faced by the BBC Sport engineering team in order to continue to innovative and deliver high performing products while establishing sound, repeatable development practices. The presentation will discuss how our practices have changed and how we strive to continually improve our automated testing and development cycle. I’ll introduce and demonstrate a number of the Open Source tools we have established and show how both the “3 Amigos Process” and sweet confections (cake) helped us learn and improve without blame.
