Mar 20, 2024 · In this video, I look at Functional Hazard Analysis with Mil-Std-882E (FHA, which is Task 208 in Mil-Std-882E). FHA analyses software, complex electronic hardware, and human interactions. I explore the aim, description, and contracting requirements of this Task, and provide extensive commentary on it.

Functional Hazard Analysis (FHA) – The primary analysis used to determine SCC and SwCI determinations for safety significant software. Each function is evaluated for level of autonomy and safety criticality. Subsystem Functional Hazard Analysis (SSHA) – A detailed subsystem analysis used to determine LOR for safety significant software.

Mar 14, 2021 · Software safety uses the FHA to assess the software contribution to the system hazards and identify software improvement opportunities. The FHA integrates risk-driven and quality assurance-driven approaches into a single safety analysis method for safe software requirements engineering.

Jan 25, 2025 · Functional Hazard Assessment (FHA) is a top-down, qualitative analysis that examines potential failure conditions associated with system functions. The primary goal of FHA is to determine how safe a system needs to be by identifying and assessing failure modes and their impact on operations and safety .

Traditional safety analysis techniques such as Functional Hazard Assessment (FHA), Fault Tree Analysis (FTA), and Failure Mode Effects Analysis (FMEA) have a long track record of being applied successfully to hardware intensive systems.

Software safety analysis consists of a number of tools and techniques to identify safety risks and formulate effective controls. Some of these techniques are used to help identify the hazards during the Hazard Analysis process, which in turn identifies the software that is safety-critical.

Functional Hazard Analysis (FHA) is an inductive hazard analysis method used to evaluate the potential causes and hazardous consequences of a system's functional failures. Software safety uses the FHA to assess the software contribution to the system hazards and identify software improvement opportunities.

Functional Hazard Analysis consistently –Mapping Exercise works • Certain tasking elements call out Probabilistic Risk Assessment (PRA) and various software (functional control) specific assessments that are based on software implementation and unique to MIL-STD-882E

Hazard analysis addresses hazards that arise in the design, development, manufacturing, construction, facilities, transportation, operations and disposal activities associated with hardware, software, maintenance, operations and environments.

Nov 7, 2019 · Software Safety Analysis (SSA) is a kind-of-a verification activity that is performed on the Software to prove that it achieves all the Safety goals and provides the required Independence and freedom from interference.
