Orchestration
Orchestration is the coordination of multiple AI agents or steps toward one outcome, rather than a single agent handling a single task.
Real work decomposes. Preparing a quarterly account review means pulling usage data, reading recent support threads, checking the renewal date and drafting a summary. Those are different tasks with different tools, and some can run at once while others must wait. Orchestration is the layer that decides the order, runs what can be parallel, and assembles the result.
It is also where failure is handled. A single agent that hits an unavailable system stops. An orchestrated run can retry that step, continue with the parts that do not depend on it, and report precisely what is missing, which is the difference between a partial result and no result.
