Risk Control Effectiveness
A practical framework for tracing a risk control from the intended safety effect through evidence, residual risk, and continued monitoring.
Make the evidence behind the risk decision traceable.
The paper focuses on the evidence needed to show that a risk control was implemented, achieves its intended safety effect, and continues to perform as expected during production and use.
Distinguish implementation, initial effectiveness, and continued effectiveness
Build a six step risk control evidence chain from risk through monitoring
Connect effectiveness evidence to the residual risk conclusion without unsupported precision
Evaluate dependencies and interactions among risk controls
Define production and post production signals that can trigger reevaluation
Use a ten question effectiveness assessment and recommended risk control matrix fields
