Analysis Layers and Relationships

ATICA places analysis information in different Capella architecture layers.

Analysis information	Capella layer	Model relationship
Aircraft- or system-level Functional Hazard Analysis	System Analysis	Failure conditions are associated with functions, flight phases, and affected entities.
Logical functions and functional failures	Logical Architecture	Functional failures can be traced to failure conditions in System Analysis or failure modes in lower layers.
Physical components and failure modes	Physical Architecture	Failure modes, causes, effects, detection methods, and functional FMEA data are defined here.
Configuration items, parts, part failures, and failure rates	EPBS Architecture	Physical components can be transitioned to configuration items for Bill of Materials work and an FMEA in EPBS Architecture.

The architecture preparation guide explains how to create or transition the structures used by an FMEA.
