1. OCEG, "GRC Capability Model," Version 3.5 (2021). The model's "Review" component (Component 4) describes activities that go beyond simple follow-up on action plans. Specifically, Element 4.3, "Monitor," involves "ongoing monitoring of the internal and external context, culture, and stakeholder needs as well as GRC activities, controls, and outcomes" (p. 58). This demonstrates that follow-up is about monitoring outcomes and effectiveness, not just the action plan itself.
2. OCEG, "GRC Capability Model," Version 3.5 (2021). The "Improve" component (within the "Review" section) emphasizes using information from monitoring and assurance to "determine and implement improvements to address the root cause of issues and mature the GRC capability" (p. 57). This confirms that the process is about resolving root causes and achieving improvement, a scope far broader than just checking off action plan items.
