Different tools for different uncertainty
Workflow automation follows explicit rules: when this happens, perform that action. AI agents operate within a goal, context, toolset, and boundary, making limited decisions when the path cannot be fully predetermined.
Use certainty where certainty exists
Approvals, data synchronization, notifications, and calculations usually belong in deterministic workflows. Classification, summarization, research, drafting, and contextual triage can benefit from an agent.
- Workflow: repeatable, auditable, predictable
- Agent: contextual, adaptive, probabilistic
- Human: accountable for exceptions and high-impact decisions
The hybrid operating pattern
A robust system uses automation as the control plane and agents as bounded intelligence. The workflow provides state, permissions, logs, and escalation. The agent handles ambiguity inside that structure.
