A technique by which many events that interact to produce other events can be related using simple logical relationships permitting a methodical building of a structure that represents the system.

An analytical tool that graphically renders the combination of faults that lead to the failure of a system.

elsmar.com

A deductive, top-down method of analyzing system design and performance. It involves specifying a top event to analyze, followed by identifying all of the associated elements in the system that could cause that top event to occur. Fault tree analyses are generally performed graphically using a logical structure of AND and OR gates. Sometimes certain elements, or basic events, may need to occur together in order for that top event to occur. In this case, these events would be arranged under an AND gate, meaning that all of the basic events would need to occur to trigger the top event. If the basic events alone would trigger the top event, then they would be grouped under an OR gate. The entire system as well as human interactions would be analyzed when performing a fault tree analysis.

A method that provides a systematic description of the combinations of possible occurrences in a system that can result in failure. It is a graphical representation of the boolean logic that relates to the result.

The process of identifying potential design weaknesses using a highly detailed logic diagram depicting basic faults and events that can lead to system failure and/or safety hazard.[ A - H | I - P | Q - Z

bizmanualz.com

A systematic way of prospectively examining a design for possible ways in which failure can occur. The analysis considers the possible direct proximate causes that could lead to the event and seeks their origins. Once this is accomplished, ways to avoid these origins and causes must be identified.

jointcommission.org

a risk management technique consisting of the identification and analysis of conditions and factors which cause or contribute to the occurrence of a defined undesirable event, usually one which significantly affects system performance, economy, safety or other required characteristics.

donald-firesmith.com

a graphical management tool for describing the cause and effect relationships that result in major failures. The fault or major failure being analyzed is identified as the "top event." All of the possible causes of the top event are identified in a tree using "or" nodes for independent causes and "and" nodes for multiple causes that must exist concurrently for a failure to occur.

mistakeproofing.com

A form of safety analysis that assesses hardware safety to provide failure statistics and sensitivity analyses that indicate the possible effect of critical failures.
