analyze any accident.
47 Materials
Compatibility
Analysis
Materials Compatibility Analysis
provides as assessment of materials
utilized within a particular design.
Any potential degradation that can
occur due to material incompatibility
is evaluated.
Materials Compatibility Analysis in
universally appropriate throughout
most systems.
48 Maximum
Credible
Accident/Worst
Case
The technique is to determine the
upper bounds on a potential
environment without regard to the
probability of occurrence of the
particular potential accident.
Similar to Scenario Analysis, this
technique is used to conduct a
System Hazard Analysis.
The technique is universally
appropriate.
49 Modeling;
Simulation
There are many forms of modeling
techniques that are used in system
engineering.
Failures, events, flows, functions,
energy forms, random variables,
hardware configuration, accident
sequences, operational tasks, all can
be modeled.
Modeling is appropriate for any
system or system safety analysis.
50 Naked Man This technique is to evaluate a system
by looking at the bare system
(controls) needed for operation
without any external features added
in order to determine the need/value
of control to decrease risk.
The technique is universally
appropriate.
51 Network Logic
Analysis
Network Logic Analysis is a method
to examine a system in terms of
mathematical representation in order
The technique is universally
appropriate to complex systems.

Summary Applicability and Use
to gain insight into a system that
might not ordinarily be achieved.
52 Operating and
Support Hazard
Analysis
The analysis is performed to identify
and evaluate hazards/risks associated
with the environment, personnel,
procedures, and equipment involved
throughout the operation of a system.
The analysis is appropriate for all
operational and support efforts.
53 Petri Net Analysis Petri Net Analysis is a method to
model unique states of a complex
system. Petri Nets can be used to
model system components, or subsystems
at a wide range of
abstraction levels; e.g., conceptual,
top – down, detail design, or actual
implementations of hardware,
software, or combinations.
The technique is universally
appropriate to complex systems.
54 Preliminary
Hazard Analysis
Preliminary Hazard Analysis (PHA)
is the initial analysis effort within
system safety.
The PHA is an extension of a
Preliminary Hazard List.
As the design matures the PHA
evolved into a system of sub-system
hazard analysis.
The technique is universally
appropriate.
55 Preliminary
Hazard List
Preliminary Hazard List (PHL) is
also an initial analysis effort within
system safety.
Lists of initial hazards or potential
accidents are listed during concept
development.
The technique is universally
appropriate.
56 Procedure
Analysis
Procedure Analysis is a step-by-step
analysis of specific procedures to
identify hazards or risks associated
with procedures.
The technique is universally
appropriate.
57 Production System
Hazard Analysis
Production System Hazard Analysis
is used to identify hazards that may
be introduced during the production
phase of system development which
could impair safety and to identify
their means of control. The interface
between the product and the
production process is examined
The technique is appropriate during
development and production of
complex systems and complex
subsystems.
58 Prototype
Development
Prototype Development provides a
Modeling/Simulation analysis the
This technique is appropriate during
the early phases of pre-production

Summary Applicability and Use
constructs early pre-production
products so that the developer may
inspect and test an early version.
and test.
59 Risk-Based
Decision Analysis
Risk-Based Decision Analysis is an
efficient approach to making rational
and defensible decisions in complex
situations.
The technique is universally
