Defect Analysis

Definition

Defect analysis is the maintenance task during which defects are analyzed so that they may be corrected.

Objectives

The typical objectives of defect analysis are to:

• Understand how to correct the defect.
• Understand the cause of the defect.
• Understand the frequency of the defect.
• Understand the impact risk associated with the defect.

Preconditions

Defect analysis typically can begin when the following preconditions hold:

• The usage phase has started.
• The initial conventions for defect analysis (e.g., guidelines, standards) have been produced during the process engineering activity.
• The maintenance team has been adequately staffed and trained in defect analysis.

Completion Criteria

Defect analysis is typically complete when the following postconditions hold:

• All identified defects have been analyzed.
• The retirement phase has started.

Steps

Defect analysis typically involves the following teams performing the following steps in an iterative, incremental, parallel, and time-boxed manner:
