Answer #1

Fault Hazard Analysis

- Must consider all functions and all failure modes.

- Utilizes list of systems and subsystem functions.

- Analysis likelihood of failure and probable effect (failure condition).

- AKA functional hazard analysis

Functional Hazard Analysis (FHA) identifies every expected function of a system and considers the hazard that may result when each function fails in every possible way. FHA does not determine causes of the failures (other than high-level attributions such as hardware failure or human error) but rather focuses on the consequences and corresponding severities. The aim is to identify the most critical hazards as a starting point for further analysis using different processes to mitigate failure causes
