Defect Life Cycle Steps
e IEEE 1044 defect life cycle consists of the following four steps
(Figure 7.2):
Step 1: Recognition or Identication Recognition occurs when we
observe an anomaly, that observation being an incident, which is a
potential defect. is can occur in any phase of the software life cycle.
Step 2: Investigation After recognition, the investigation of the inci-
dent occurs. Investigation can reveal related issues. Investigation can
propose solutions. One solution is to conclude that the incident does
not arise from an actual defect; for example, it might be a problem in
the test data.
Step 3: Action ...
