As organizations move beyond simple Q&A copilots, a common challenge quickly emerges: single agents struggle to handle multi-step, cross-domain scenarios. In our work with customers using Microsoft Copilot Studio, this shows up when copilots are expected to combine reasoning, real-time data, and domain-specific rules, such as troubleshooting workflows, aggregating system insights, or synthesizing information from multiple business areas. Multi-agent orchestration addresses this challenge by allowing copilots to delegate work to specialized agents while keeping a single decision layer.
