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.
