Flight Recorders: Analyze and Fix Defects Quickly

Oliver Cole, OC Systems, Inc.

Users find 25 percent of your defects after your software goes live, according to a recent study. In addition to being expensive to fix, these post-ship defects often prove impossible to find due to the many potential user environments out there. Flight recorders are new tools, named after those already present on aircraft, that trace the execution of an application in or before production. Their job is to collect information while the system runs. Then, if a problem or failure occurs, you can examine the trace file and discover what operations led to the problem without actually having to recreate the problem.
