By the end of this module you should be able to:
- Separate design target from SLA
- Understand observability
- Recognise the need for end-to-end metrics
Targets versus guarantees
A standards-defined service type or 5QI does not automatically create a contractual guarantee. An SLA must define the metric, measurement point, time window, exclusions and remedy.
End-to-end observability
Operators need telemetry across RAN, transport, Core, edge and service platforms. Without correlated data, it is difficult to prove why performance changed.
Enterprise evidence
Customers may need dashboards, APIs, reports and alarms showing availability, latency, packet loss, throughput or device registration state. Assurance is part of the product, not an afterthought.
Knowledge check
What turns a performance aim into an SLA?
