Guenier called the job of scouring raw code for dates that might be problematic an “exceptionally boring and unglamorous undertaking” that involved repeated rounds of testing, because changing code could cause issues elsewhere in the system. It was an enormous job. Martyn Thomas, who ran Y2K remediation efforts internationally for Deloitte, recalled the work for the finance division of General Motors in Europe: “We put together a small army of people, rented an aircraft hangar and bought three or four hundred PCs so we could run the scanning and repair equipment needed. And that was just one example of what was happening all over the world.”
