> Some industries would not allow software to be released more than every few months. SQA needs to sign off. Users need to UAT. 2-week notice, 15-minute notice to log off. Downtime needs to be communicated to multiple time zones. Software versions need to be auditable for regulatory.

As a person who works in a heavily regulated field ($$$), all the audit / traceability requirements apply. We still move fast (multiple releases a day) because we have demonstrated that it reduces risk and promotes stability — something regulators are very interested in. In concrete terms, faster release rates are correlated with lower sevs (or incidents). But the underlying cause is really that faster release rates cause teams to adopt more reliable delivery practices, such as automated testing, gradual deployments, and so on.
