ODC - Orthogonal Defect Classification

Trigger Definitions

There are three classes of triggers associated with the three most common activities of verification. Since each of the activities tend to be very different from one another, they call for different sets of triggers. System test, function test and review/inspection form the three substantially distinct verification activities. The distinction arises from how they attempt to detect faults. In one form or another they all attempt to emulate customer usage. However, the level of observability of the code and function vary and the issues addressed are driven by different motivations. Thus, triggers for each of these classes of verification are unique. In the following subsections we define each of these verification classes and their triggers.

• System Test Triggers
• Review and Inspection Triggers
• Function Test Triggers
