The goal is to sustainably build software, which only can be done if ops and maintenance is regarded a goal, a pillar to build upon. Like TDD the design of software changes when you have experience with ops/maintenance. Take logging/tracing: what to log or trace is first and foremost a matter of experience with maintenance/ops! Building in logging/tracing/monitoring from the get-go because you know that you want to know what goes wrong, when it goes wrong etc... can one regard oneself as expert if you know only a part of the domain- I think not!
