Fault tree analysis (FTA) is a tool that begins at the point of failure and works back through the process to the components. FTA is used to identify the root causes of system failures by constructing a logical diagram of the various possible causes. This method helps in understanding the paths leading to a failure and identifying corrective actions. Reference: "Reliability, Maintainability, and Risk" by David J. Smith, which describes fault tree analysis and its application in failure analysis.

When subgroups are selected in a way that minimizes the opportunity for variation within a subgroup and maximizes the opportunity to detect variation between subgroups, this subgrouping is known as rational subgrouping. Rational subgrouping is a concept used in control charting to ensure that the data within each subgroup is homogeneous, making it easier to detect special causes of variation between subgroups.References:

Severity in the context of software quality and risk management refers to the extent of impact a failure would have on a system or process.

It assesses the consequences of a failure, regardless of its likelihood or detectability.

High severity indicates significant detrimental effects, such as critical system failures or safety hazards.

References: The ASQ and FMEA (Failure Mode and Effects Analysis) methodology define severity as the measure of the seriousness of the effect of a failure mode.
