Can Your Continuity Plan Work Without Its Usual Decision-Maker?

A backup process can look complete on paper and still depend on one person to approve every exception.

Imagine a critical supplier becomes unavailable for a week. The team has a workaround, but the usual decision-maker is unreachable. What should a continuity drill test to show that the team can keep essential work moving without exceeding its authority? Should it test who can approve the workaround, what limits they must stay within, or how the team escalates a decision that crosses those limits?
