ExpaiaAgent System Design Patterns for the Enterprise
An overview of single-agent, router, and multi-agent design patterns and when to use each in enterprise workflows.
Choosing the right agent architecture
Not every workflow needs a fleet of collaborating agents. Understanding the continuum from single-agent to multi-agent systems helps you match complexity to the problem.
Single-agent systems
Best for focused, well-defined tasks. One agent connects to specific tools and executes a clear workflow.
Use when: The task has a clear input/output, limited decision branching, and doesn’t require coordination with other processes.
Router-based systems
A router agent receives tasks and delegates them to specialized sub-agents. This pattern scales well when you have diverse task types but want centralized orchestration.
Use when: You have multiple distinct workflows that share common triggers or data sources.
Multi-agent collaboration
Multiple agents share context and coordinate actions. This pattern handles complex, multi-step processes where different agents bring specialized capabilities.
Use when: The workflow crosses system boundaries, requires parallel execution, or involves negotiation between competing objectives.
Getting started
Start simple. Deploy a single agent for your highest-value workflow, measure outcomes, then expand. Expaia’s platform supports all three patterns and makes it straightforward to evolve your agent architecture as needs grow.
