These notes reference specific Softwareinfrastructure modules. Voices vary on purpose—some brief, some reserved.
Short take: the ITGC interview script in Foundations is the piece I still open before vendor SOC calls.

“I wanted more Korea-specific tax examples. Even so, the related-party disclosure lab cleaned up our shareholder loan note.”

“Peer review pairs were awkward at first, then useful—someone finally challenged our cut-off memo language.”

Case study · Wallet startup, first external audit
A Seoul-based wallet with 42 employees joined Controllership Lab twelve weeks before fieldwork. Their trial balance was clean; their evidence was not. Processor reports lived in email threads, and chargeback reserves lacked a roll-forward.
During the Lab’s systems-map session, the team listed seven data owners and discovered two dormant admin accounts that would have surfaced in ITGC inquiries. They rebuilt a weekly settlement reconciliation tied to assertion language from the Foundations binder checklist.
Outcome: auditors still asked follow-ups on loyalty points, but the PBC first round closed in nine business days instead of the prior informal estimate of three weeks. The finance lead credited the mock PBC drill—not generic “soft skills.”
Case study · Lending desk rebuilding disclosures
A consumer lending team enrolled two analysts in Assurance Studio after an investor due-diligence request flagged thin ECL commentary. Coursework on valuation support files forced them to document model inputs beside the journal entries.
They noted one limitation: live sessions assume English working papers; their Korean statutory pack still needed local review. Within the English investor pack, though, the ECL bridge became reusable for the next board packet.
