The Four Domains of Analytical Reliability
The analytical reliability framework is organized into four domains. Each domain captures a different way that analytics systems can fail while still appearing healthy.
Domains
-
Data Movement Reliability
Ingestion, transformation, and delivery remain correct and complete across the pipeline.
-
Semantic Reliability
Models, metrics, and relationships preserve the intended meaning of the data.
-
Execution Reliability
Query behavior remains consistent at runtime despite workload or infrastructure change.
-
Change Reliability
Updates to code, models, and configuration do not introduce hidden analytical regressions.
How the Domains Work Together
Failures in one domain often cascade into others. Analytical reliability requires visibility across data movement, semantics, execution behavior, and change processes.
