Service Availability Management Maturity Assessment

About this assessment

This assessment asks whether the organization knows how available each critical service must be and what an outage costs, whether services are designed, monitored, tested, maintained and supported to meet those targets, and whether the availability users actually experience is proven. It starts with governance: the availability policy, a register of regulatory, critical infrastructure, contract and data residency obligations, roles, criticality tiers drawn from business impact analysis, a measurement standard that counts degraded service, and analyst competency. Requirements cover vital business functions, cost of downtime, targets, reliability requirements for new services and planned downtime. Design and analysis test the resilience standard, graceful degradation, dependency maps that include hidden shared services such as name resolution, certificates and identity, single points of failure in components, people, credentials and tools, fault trees, predicted availability and design review. Monitoring is assessed at two levels that are often confused: component health coverage, and end-to-end monitoring of each vital business function from the user's view, with delivered availability calculated from the end-to-end signal, reliability data collected from real outages and failures predicted before they happen. Resilience operations test redundancy health, denial of service protection, failover tests, controlled resilience experiments, safety limits on automation and AI agents that can change production, and break-glass and out-of-band access for when the usual paths are down. Maintainability covers maintenance strategy chosen from failure modes, preventive maintenance, downtime minimization, staged release of changes and vendor-pushed updates, prevention of outages from expired certificates, keys and contracts, restoration including cold start order, spares and unsupported components. Supplier and dependency questions address contracted availability, cloud zones and regions within data residency limits, supplier monitoring, shared platforms, power, cooling and carrier route diversity including subsea paths, concentration on one provider, route or country, and AI model provider fallback. The final domains test risk treatment, reporting, outage analysis, cost of downtime, error budgets, the availability plan and measured improvement. Each question is scored on whether the practice is documented, carried out and demonstrably effective, so results show whether a gap is a missing standard, an adoption problem or a lack of evidence.
