Glossary » defect tracking
typically refers to identifying flaws appearing during manufacturing, which in software design normally pertains to the translation from design specs to finished software. The goal is not only to spot defects but to track them and identify the source of the problem to prevent them. Were specs incomplete, impractical, or poorly specified? Were they unavailable, or was the production process unsupportive of their effective use? Defects may also have their source outside the actual software being developed, in the hardware or operating system, for instance.
