Orchestrator-Subagent Fan-Out and Fan-In (CCAR-P)

Design multi-agent systems and orchestration strategies

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
An orchestrator decomposes a large job into independent units and dispatches them to subagents running in parallel; each subagent returns a verdict or result, and a synthesis step aggregates the fanned-out results into one output. Fan-out reduces latency for independent units compared with processing them one at a time, and the orchestrator, not the subagents, owns the decomposition and the aggregation logic.
