The document discusses defect management and defect prevention processes. It describes common causes of software defects, different types of defect classifications, the defect management lifecycle which includes discovery, resolution and prevention. It also lists techniques for finding defects such as static, dynamic and operational methods. Finally, it outlines fields for logging defect details in a standardized format.

12. Deliverable Baseline. A deliverable (e.g. work product) is
baseline when it reaches a predefined milestone in its
development. This milestone involves transferring the
product from one stage of development to the next.

13. Defect resolution:
Prioritize
Schedule
Fix defect
Document resolution
Defect Discovery:
Identification and reporting of defect .
Finding defect when it is documented and acknowledgment.
