★★★★★
We used the dual-control matrix during a real staff transition. The backup signer knew exactly which sealed bag was theirs without a frantic call.

What changed after the worksheets
Feedback from individuals and teams who treated rotation as a planned project. Ratings and stories vary — we keep the awkward bits too.
★★★★☆
Clear writing. A bit dense in module three, but the rehearsal script paid for the tuition in one afternoon.
★★★★★
“Finally, runbooks that legal will read.” That was our CISO’s note after Vault Circle week four.
★★★★☆
Anonymous client in brokerage operations: the evidence notebook module stopped us from photographing seed material “for the wiki.” That correction alone was worth the course.
Case study
Three-signer team, one shared calendar
A Yongin-adjacent startup had three hardware devices and no written order of operations. After Blueprint Access, they drafted a quarterly cadence tied to payroll week — when everyone was already in-office. Their first tabletop revealed a missing witness role; they added a rotating observer from finance before any live move.
Outcome they reported: ceremony time dropped from an anxious Saturday to a timed 70-minute weekday slot. We did not custody assets or validate balances for them.
Case study
Remote CFO, local device custodian
A distributed collective struggled with dual control across time zones. Rotation Studio reviews helped them split “approve” from “physically present” so the CFO could sign off on video while a custodian in Korea handled the room. Interrupt drills caught a habit of skipping the abort checklist when someone was late.
They still schedule live rotations only when both roles confirm 48 hours ahead — a policy they wrote, not one we impose.
