The popular SMART model provides a framework for defining criteria that are:
2.2 Failure Modes and Effects Analysis (FMEA):
This model identifies potential failure modes and their effects on the system under test. By analyzing the severity, likelihood, and detectability of each failure mode, FMEA helps define specific criteria to mitigate potential risks.
2.3 Hazard and Operability Studies (HAZOP):
HAZOP is a structured approach for identifying potential hazards and operational issues associated with a system or process. This model involves a systematic review of the system, identifying deviations from intended operation and developing corresponding test criteria to prevent or mitigate these deviations.
2.4 Risk Assessment Matrix:
This model uses a matrix to assess the risk associated with various parameters, considering both the probability of occurrence and the potential consequences. The matrix helps prioritize testing efforts, focusing on parameters with higher risk levels.
