Two questions about your infrastructure
Two questions tell you most of what you need to know about a team's infrastructure: how long a deployment takes, and when the backups were last restored. If the answers are "an evening" and "never", that is where to start.
We set up infrastructure as code so environments are reproducible, pipelines so releasing is unremarkable, and monitoring that tells you about a problem before a customer does. Then we go through the cloud bill line by line, because most are a third larger than they need to be.
