IEEE Standard Classification for Software Anomalies

IEEE Standard Classification for Software Anomalies

1. 4- phase resolution process

   • Step 1: Recognition
     • Step 2: Investigation
       • Step 3: Action
         • Step 4: Disposition
           • There is only one level of categorization during the Disposition phase.
             • Resolution implemented
         • During the action phase, anomalies are classified according to
           • Resolution
             • Corrective action
       • During the investigation phase, anomalies are classified according to
         • Actual cause
           • Source
             • Type
     • During the recognition phase, anomalies are classified according to
       • Project activity
         • Project phase
           • Suspected cause
             • Repeatability
               • System symptom
                 • Product status

2. This standard accommodates the center arrangement of traits for grouping of defects and failures

   • provides a highly detailed classification scheme
     • It is perceived that there are different properties of defects or fails that are of interesting an incentive to explicit software or business necessities.

3. Impact clasification used

   • Severity
     • Priority
       • Customer Value

4. Relationships

   • Problem-Failure
     • Failure-Fault
       • Fault-Defect
         • Defect-Change Request
           • A defect may be removed via completion of a corrective change request. A corrective change request is intended to remove a defect. (A change request may also be initiated to perform adaptive or perfective maintenance.)
         • A fault is a subtype of the supertype defect. Every fault is a defect, but not every defect is a fault. A defect is a fault if it is encountered during software execution (thus causing a failure). A defect is not a fault if it is detected by inspection or static analysis and removed prior to executing the software.
       • A failure may be caused by (and thus indicate the presence of) a fault.
         • A fault may cause one or more failures.
     • A problem may be caused by one or more failures.
       • A failure may cause one or more problems
