Control Design & Implementation, Execution & Effectiveness Testing: What's the Difference?
In the CERRIX platform, controls are a central component of your governance, risk, and compliance framework. Understanding the different types of control activities and testing phases is essential for effective risk mitigation and assurance.
This article explains the differences between Control Design & Implementation Testing, Control Execution, and Control Effectiveness Testing.
Control Design & Implementation Testing
Definition: This is a test of the suitability and proper setup of the control. It determines whether the control, as designed and implemented, is capable of addressing the associated risk.
Purpose: To assess whether the control is appropriate and has been set up correctly within business processes or IT systems.
Example: Reviewing if a purchase approval workflow enforces segregation of duties between requester and approver.
In CERRIX: Documented in the Control Library or during Control Assessment workflows, often by second or third line teams (Compliance, Audit). Testing results are stored and linked to the control for transparency and auditability.
Control Execution
Definition: Control execution refers to the actual performance of a control activity by the responsible party or system, according to its defined frequency and procedure.
Purpose: Ensure that the control is carried out as designed, on time, and by the appropriate stakeholder.
Example: A weekly review of user access logs performed by an IT administrator.
In CERRIX: Control execution is logged through the Control Monitoring module. Control owners receive automated tasks or notifications to perform and evidence control activities.
Control Advanced Effectiveness Testing
Definition: This test checks whether the control operates effectively over time. It involves reviewing historical evidence to confirm that the control consistently works as intended.
Purpose: To validate that the control not only exists but also reliably mitigates the associated risk.
Example: Sampling the past 6 months of control executions to verify timely and complete access reviews were performed.
In CERRIX: Performed through the Control Advanced Effectiveness Testing feature, allowing testers to upload sampling results, attach evidence, and rate control performance (e.g., effective, partially effective, ineffective).
