risk_config_default: Default Risk Configuration

In r4subrisk: Risk Quantification Engine for Clinical Submission Readiness

Default Risk Configuration

Description

Returns configuration for risk assessment including FMEA scale definitions, RPN thresholds, and risk level classification bands.

Usage

risk_config_default(
  rpn_bands = list(critical = c(80, 125), high = c(40, 79), medium = c(15, 39), low =
    c(1, 14)),
  evidence_severity_to_probability = c(info = 1, low = 2, medium = 3, high = 4, critical
    = 5),
  evidence_severity_to_impact = c(info = 1, low = 2, medium = 3, high = 4, critical = 5),
  default_detectability = 3
)

Arguments

rpn_bands	Named list of RPN band boundaries c(lower, upper). Evaluated in order; first match wins.
evidence_severity_to_probability	Named numeric vector mapping evidence severity to probability scores (1–5 scale).
evidence_severity_to_impact	Named numeric vector mapping evidence severity to impact scores (1–5 scale).
default_detectability	Default detectability score (1–5) when not explicitly provided. Lower = more detectable.

Details

The FMEA-inspired risk model uses three dimensions:

• Probability (1–5): likelihood of the issue occurring/persisting

• Impact (1–5): severity of consequence if unresolved

• Detectability (1–5): difficulty of detecting the issue (1 = easy, 5 = hard)

RPN = Probability x Impact x Detectability (range 1–125)

Value

A list of class "risk_config" with elements: rpn_bands, evidence_severity_to_probability, evidence_severity_to_impact, default_detectability.

Examples

cfg <- risk_config_default()
cfg$rpn_bands
