The bow-tie technique was first developed as a technique for developing safety cases in the Oil and Gas Industry. The principle of the technique requires the identification of hazards, circumstances (threats) and events leading to the risk realisation (usually as a fault tree), and then, a tree of consequences leading from the event to the consequences and the estimated loss (usually with an event tree).

Goal Structuring Notation (GSN) and Claim Trees are two similar techniques used to present an explanation of how the available evidence can be interpreted to indicate the achievement of a top-level claim or assertion, for example that a system is tolerably safe.

Functional Safety Analysis is an approach that assesses all the system functions to determine the hazards associated with what the system does. The purpose of Functional Safety Analysis is to identify hazards associated with both the correct and incorrect operation and non-operation of the system, lower level functions and human functions.

Failure modes and effects analysis (FMEA) is a reliability evaluation technique to determine the effect of system and equipment failures. This qualitative technique helps identify failure potential in a design or process i.e. to foresee failure before it actually happens.
A FMECA is an analytical quantitative technique which ranks failure modes according to their probability and consequences.
