Glossary › Control Effectiveness Index
What is Control Effectiveness Index?
The Control Effectiveness Index provides a metric for assessing whether controls achieve their intended purpose. It incorporates testing results, incident trends, and audit findings. In TPRM, this index helps evaluate vendor control maturity and identify areas where additional safeguards or remediation may be necessary.
FAQs

Does the index rely only on self-assessments?
No, it should include independent evidence such as audits and testing.
Is a high index score always sufficient?
High scores must still be supported by ongoing monitoring and validation.
