Compare Risk Registers (Trend Analysis)

Description

Compares two risk register snapshots and reports changes in RPN, new risks, resolved risks, and risk level transitions.

Usage

compare_risk_registers(before, after)

Arguments

before	A risk_register (earlier snapshot).
after	A risk_register (later snapshot).

Value

A list with:

• rpn_changes: tibble of risks with changed RPN

• new_risks: risk_ids present in after but not before

• resolved_risks: risk_ids present in before but not after

• level_transitions: tibble of risk level changes

• delta_mean_rpn: change in mean RPN

Examples

r1 <- data.frame(
  risk_id = c("R001", "R002"),
  description = c("Missing vars", "Bad derivation"),
  probability = c(4, 3), impact = c(5, 4), detectability = c(2, 3)
)
r2 <- data.frame(
  risk_id = c("R001", "R003"),
  description = c("Missing vars", "New issue"),
  probability = c(2, 3), impact = c(5, 3), detectability = c(2, 2)
)
rr1 <- create_risk_register(r1)
rr2 <- create_risk_register(r2)
compare_risk_registers(rr1, rr2)
