Safe changes, workarounds and rollback in support work
The in-the-moment decisions a support technician makes before touching a customer's system: is this change reversible, how big is the blast radius, what's the current state, who must agree, how do I try it small first, and what makes me roll back. Builds on your organization's formal change process; it doesn't replace it.
