Rolf Russell & Andy Duncan discuss how to have rapid and reliable releases from the perspective of build, release, and devops, considering the relationship between the teams involved, the metrics needed to measure the performance achieved, the required skills, and the need to remove waste and bottlenecks.
Dan North discusses an example of rearchitecting an application without rewriting it from scratch, and explains general strategies for a holistic rearchitecture such as changing the team culture, removing obsolete technologies, allowing mistakes to be made (and learned from), transitional architectures, introducing bounded contexts, refactoring and emergent simplicity, and rotating through roles.
