1. Executive Summary & Purpose

This SOP establishes the standardized methodology for maintaining a Risk Register compliant with ISO 31000:2018 principles. The purpose is to provide a structured mechanism for identifying, assessing, treating, and monitoring organizational risks to ensure systemic resilience and informed decision-making.

2. Scope & Prerequisites

• Scope: Applies to all operational, financial, and strategic risk assessments within Template Registry.
• Prerequisites:
  • Access to the centralized Risk Management Information System (RMIS).
  • Approved "ISO 31000 Risk Assessment Matrix" (Likelihood x Impact).
  • Read/Write access to the organizational Risk Register repository.

3. Roles & Responsibilities (RACI Matrix)

4. Step-by-Step Procedure

Phase I: Identification

• Conduct stakeholder interviews to solicit internal and external risk factors.
• Log risk events in the "Risk ID" column using the format ISO-RR-[YYYY]-[SEQ].
• Categorize risks (e.g., Strategic, Operational, Compliance, Financial).

Phase II: Assessment (Inherent Risk)

• Determine Likelihood (1: Rare to 5: Almost Certain).
• Determine Impact (1: Insignificant to 5: Catastrophic).
• Calculate Risk Score (Likelihood × Impact).
• Assign color-coded severity: Low (1-4), Medium (5-9), High (10-16), Extreme (20-25).

Phase III: Treatment & Monitoring

• Select treatment strategy: Accept, Avoid, Transfer, or Mitigate.
• Assign "Risk Owner" and define "Mitigation Controls."
• Set "Residual Risk" score post-control implementation.
• Establish "Trigger Dates" for periodic re-evaluation.

5. Quality Assurance & Pro-Tips

• Metric Thresholds: Any "Extreme" risk score requires an immediate management response plan (within 48 hours).
• Pro-Tip (Normalization): Standardize impact definitions across all departments to prevent "optimism bias" where one department views a $50k loss as "Minor" while another views it as "Major."
• Common Pitfall: Treating the Risk Register as a "set-and-forget" document. It must be a living repository reviewed at every operational steering meeting.

6. Frequently Asked Questions

Q: How do I differentiate between an Issue and a Risk?

• A: An Issue is an event that has already occurred and is impacting operations. A Risk is a potential future event that might occur. Log current impacts in the Issue Log; log potential threats in the Risk Register.

Q: What is the primary difference between Inherent and Residual risk?

• A: Inherent risk is the raw exposure before controls. Residual risk is the exposure remaining after existing mitigation controls are applied. Always document both to demonstrate the effectiveness of your controls.
