Systems Engineering Topics

Checklists
Can be used as a basic method for itemizing potential hazards or undesirable outcomes that need to be considered.
CMFA
Abbreviation of Common Mode Failure Analysis.
Common Mode Failure Analysis
CMFA evaluates the impact of coincidental failure in different parts of a complete system.
Delphi Techniques
These techniques involve processes for combining expert opinions from different sources into a model for estimating risk.
Event Tree Analysis
This technique uses inductive reasoning to translate different initiating events into possible outcomes.
Fail Safe System
A system used to minimize risk in case of a malfunction.
Failure
The event, or inoperable state, in which any item or part of an item does not, or would not, perform as previously specified.
Failure Mode
The way in which a component fails to operate or perform a function.
Failure Mode and Effects Analysis
A procedure by which each potential failure mode of a system is analyzed to determine the effects on the system and classify each potential failure mode according to its severity.
Fault Tree Analysis
This identifies each undesired event and determines all the ways in which it could occur.
FMEA
A procedure by which each potential failure mode of a system is analyzed to determine the effects on the system and classify each potential failure mode according to its severity.
Hazard and Operability Studies
HAZOP studies examine each part of an entire system to determine how deviations from the intended function or performance can lead to undesirable outcomes.
Hazard Indices
These can be used to analyze different system options in order to identify that option having the lowest risk.
Hazard Quotient
The ratio of the potential exposure to the substance and the level at which no adverse effects are expected.
HAZOP
Abbreviation of Hazard and Operability Studies.
Mean Time Between Failure
The average time between failures for a continuously operating system.
Mean Time to Failure
The measured operating time of a system or component divided by the number of failures that occurred during that time.
Preliminary Analysis
This is a hazard identification and frequency analysis technique that can be used to assess potential hazards at an early design stage.
Propagation Test
Test to look at how an event such as combustion propagates from one component to the next.
Reliability
The probability of specified performance for a given period of time when used in the specified manner.
Reliability Block Diagram
A graphical frequency analysis technique that uses system models to investigate overall reliability.
Resilience
Amount of change a system can undergo without changing state.
Response Time
The time needed for the system or its components to re-equilibrate to a new state, following a forcing resulting from external or internal processes or feedbacks.
Statistical Process Control
Statistical techniques to measure and analyse the extent to which a process deviates from a set standard.

Technology Readiness Level
A measure used to assess the maturity of evolving technologies prior to incorporating that technology into a system or subsystem.
Transient Response
The ability of a system to respond quickly and accurately to transients.
