FAP
Shape functions, interfaces and dependencies before the architecture is locked.
Overview
FAP is the bridge between requirements and architecture. It helps teams decompose features into functions, map interfaces and dependencies, and reason about behaviour early — while change is still cheap.
By structuring the functional picture up front, FAP keeps the later architecture honest and gives every downstream product a clear model of what the system is meant to do.
Key capabilities
Feature decomposition
Break features into functions with clear ownership, inputs and outputs.
Interface & dependency mapping
Visualise how functions interact before they become architectural commitments.
Early behaviour reasoning
Surface conflicts and gaps while they are inexpensive to fix.
Hand-off to architecture
Feed a clean functional baseline straight into AurigaArch.
