Use 100% automated fixes for known problems that don't require manual intervention. Good for known problems with known workarounds.
Instead of granting access to production, grant access to Robusta. Let users run pre-approved fixes and nothing else.
Define best practices for handling and fixing alerts. Encourage users to respond according to plan and not with ad-hoc fixes. Using automation, make the best fix the fastest one too.
