Disk drive manufacturing may produce more than 50,000 drives per day at a single plant. Discs that fail their quality assurance check must have a determination of the fault and the proper repair strategy. Blaze Advisor is used to drive Seagate’s automated fault diagnosis system. Rules may be updated by technicians and engineers without specialized computer programmers. This has reduced the average diagnosis time from minutes to seconds and led to production capacity increases for the plant. In addition the system can "learn" much faster as system diagnostic and remediation rules can be changed in days instead of weeks. The Fair Isaac website has a complete Seagate case study.
