I would sincerely hope that my colleagues always assume that there WILL be problems that impact availability when dabbling in production environment. I'd rather have a guy spend whole day making sure everything is working and rechecking, etc. I also hope that my colleagues will have the foresight to test an update/deployment on as fresh mirror of production environment (or a representative subset) as possible. And I'd say that this is ESPECIALLY important for NoSQL environments.
