The Bottom Line

Four risk attributes capture each Service’s risk posture — Service Risk Rating (High / Medium / Low), Single Point of Failure Flag, Business Continuity Plan Reference, and Related Risk Records. These Walk-maturity attributes connect the Services Inventory to enterprise risk management and support risk-informed Service portfolio prioritization.

Core Concepts

Concept	Definition & Strategic Role
Service Risk Rating	A composite High / Medium / Low rating set by the Service Owner with input from risk and security teams — drives risk-based prioritization.
Single Point of Failure Flag	Yes / No — surfaces concentration risk; Services flagged Yes warrant explicit mitigation plans or continuity arrangements.
Business Continuity Plan Reference	A pointer to the BCP that addresses the Service — connects the inventory record to the continuity discipline.
Related Risk Records	Risk records in the planned Risks Inventory associated with this Service — enables risk-informed Service governance.

Quick Q&A

Question: What action should the Service Owner take when the Single Point of Failure Flag is Yes?

Answer: Document an explicit mitigation plan or business continuity arrangement — capture it in the Business Continuity Plan Reference attribute. A SPOF without a documented mitigation is an unmanaged enterprise risk; flagging the Service is the first step, but the flag is meaningful only when paired with an actionable plan.

Question: How does Service Risk Rating differ from Service Tier and Strategic Importance?

Answer: Service Tier measures operational criticality (what happens if degraded); Strategic Importance measures strategic positioning (mission centrality); Service Risk Rating measures aggregate risk the Service represents (likelihood and impact across security, compliance, operational, vendor, and other risk dimensions). The three are independent — a Tier 4 commodity Service may be High Risk if it depends on a single Vendor with concentration risk; a Tier 1 Mission-Critical Service may be Low Risk if it has redundant providers and proven continuity.

Risk attributes capture the risk posture of each Service — its risk rating, whether it is a single point of failure, its business continuity plan reference, and related risk records. These attributes connect the Services Inventory to enterprise risk management.

Attribute Name	Maturity	Description and Notes
Service Risk Rating	Walk	Description — A composite risk rating for the Service, capturing the aggregate risk the Service represents to the enterprise. Benefit(s) — Enables risk-based Service portfolio prioritization. Supports risk-informed governance investment. Source — Manual. Examples — High, Medium, Low Notes — Valid values: High, Medium, Low. Should be set by the Service Owner with input from risk and security teams.
Single Point of Failure Flag	Walk	Description — Whether the Service is a single point of failure for one or more critical enterprise processes. Benefit(s) — Surfaces concentration risk. Enables resilience investment prioritization. Source — Manual. Examples — Yes, No Notes — A Service flagged Yes should have a documented mitigation plan or business continuity arrangement.
Business Continuity Plan Reference	Walk	Description — A reference to the business continuity plan that addresses the Service. Benefit(s) — Connects Services to their continuity plans. Supports continuity discipline and audit. Source — Manual. Examples — BCP-IT-001; SharePoint document URL Notes — Empty for Services not subject to formal continuity planning.
Related Risk Records [Multi-Value]	Walk	Description — Risk records in the planned Risks Inventory associated with this Service. Benefit(s) — Connects Services to the formal risk register. Enables risk-informed Service governance. Source — Manual. Examples — RSK-VENDOR-LOCK-IN; RSK-COMPLIANCE-DATA-RESIDENCY Notes — Refer to the planned Risks Inventory for risk governance.
