12 Workflows, 1 Conversation: Conversational AI for a Global Professional-Services Firm
A Gemini Enterprise-powered assistant orchestrating twelve specialized AI agents behind a single conversational interface, with sensitive matters routed to humans.
What made this hard.
- Twelve HR workflows spread across disconnected HRMS screens.
- Routine tasks taking 6–9 minutes of navigation.
- Routine tickets consuming capacity needed for sensitive cases.
- PeopleSoft as the system of record that couldn't be duplicated.
- Clear boundary needed for AI vs human judgment.
How we engineered the solution.
Gemini Enterprise orchestration routing to twelve sub-agents via A2A protocol.
Independent agents built on Agent Development Kit, one capability each.
MuleSoft integration keeping PeopleSoft untouched.
Escalation agent, model-tier optimization, and Vertex AI tracing.
The biggest shift wasn't building agents. It was orchestrating them, and knowing where they should stop.
What this engagement proved.
Orchestration beats consolidation for modular AI.
Best agentic designs show where AI should stop.
Conversational layers succeed when the system of record stays untouched.
Observability is a first-class requirement in multi-agent systems.
