The Bottom Line

Assessment and Health attributes provide the considered view of Service health — Service Health Rating (Green / Yellow / Red), Customer Satisfaction Score, and Last Health Assessment Date. These are governance-level signals distinct from real-time operational monitoring: the assessment captures the periodic review judgment, not the moment-by-moment operational state which lives in the monitoring system.

Core Concepts

Concept	Definition & Strategic Role
Service Health Rating	A summary Green / Yellow / Red rating set by the Service Owner based on aggregated operational signals — performance against objectives, satisfaction, incident frequency, governance findings.
Customer Satisfaction Score	Quantitative consumer-side feedback distinct from internal operational metrics — captured through Requester surveys or Service Owner-conducted reviews.
Last Health Assessment Date	The timestamp anchor for assessment overdue-detection — distinct from Last Governance Review Date because health assessment and governance review may run on different cadences.

Quick Q&A

Question: Why are operational telemetry metrics like uptime percentage and MTTR not included in this category?

Answer: Because operational telemetry belongs in monitoring systems, not in an inventory. The Services Inventory is for governance attributes that change deliberately (the Service Owner sets the Health Rating after review); the monitoring system tracks metrics that change continuously (uptime is recalculated every minute). Putting telemetry in the inventory creates stale data and the wrong system of record.

Question: How is Service Health Rating different from Service Availability Status?

Answer: Service Availability Status is the current operational state (Available, Degraded, Unavailable, Maintenance) and changes minute-to-minute. Service Health Rating is the considered governance judgment (Green, Yellow, Red) set by the Service Owner after periodic review and changes deliberately on assessment cadence. Health is a judgment; availability is a state.

Assessment and Health attributes record the current health and consumer-satisfaction state of each Service. These attributes provide governance visibility distinct from real-time operational monitoring — the assessment captures the considered view of Service health, not the moment-by-moment operational state.

Attribute Name	Maturity	Description and Notes
Service Health Rating	Walk	Description — A summary rating of the Service’s current health, typically derived from multiple operational signals (performance against objectives, customer satisfaction, incident frequency, governance review findings). Benefit(s) — Provides leadership-level Service portfolio health visibility. Enables prioritization of Service improvement investment. Supports the IF4IT Service Management Best Practices "Use lifecycle data to improve Service Portfolio decisions" guidance. Source — Manual. Examples — Green (healthy), Yellow (attention needed), Red (action required) Notes — Valid values: Green, Yellow, Red. Updated by the Service Owner based on review of operational data, not by automated systems alone. May be Calculated in mature implementations from underlying metrics.
Customer Satisfaction Score	Walk	Description — The most recent customer satisfaction measurement for the Service, typically captured through Service Requester surveys after Service Request closure or through periodic Service Owner-conducted reviews. Benefit(s) — Provides quantitative consumer-side feedback distinct from internal operational metrics. Enables comparison across Services and over time. Supports Service improvement prioritization based on consumer experience. Source — Manual. Examples — 4.2 (out of 5), 87% (satisfied or very satisfied) Notes — Record the measurement scale alongside the value. Should be updated when new measurements become available. May be Derived from survey tools in mature implementations.
Last Health Assessment Date	Walk	Description — The date of the most recent formal Service health assessment. Benefit(s) — Enables overdue-assessment detection. Supports the discipline of regular Service health review distinct from operational monitoring. Source — Manual. Examples — 2026-04-30 Notes — Distinct from Last Governance Review Date — the health assessment may occur outside the formal governance review cycle.
