ASK to Multi-Agent
Employee Intelligence

Built 0→1 inside a 10,000-person org with no mandate, no budget, no prior AI infrastructure. Today it handles 40,000+ queries a month across HR, IT, and Finance to autonomously.

Monthly saving: 60% of 40,000 queries deflected = 24,000 resolved autonomously. (₹850 − ₹17) × 24,000 = ₹2 crore/month in operational cost avoidance. This number is what convinced Finance to invest in the enterprise platform layer.

User Personas
Engineer · 5+ yrs

Praveenkumar

Pain: 3 different portals for 3 different questions. Never knows who to contact first.

Needs: One place to ask anything. Self-service for leave, IT assets, travel policy.

HR Representative

Aishwarya

Pain: Answers the same 20 questions 50 times a week. Can't focus on strategic HR work.

Needs: Repetitive queries automated. Escalation only for genuinely complex issues.

New Joinee · Day 1

Dimple

Pain: Afraid to bother senior colleagues. Onboarding doc is 200 pages.

Needs: Ask anything without judgment. Instant answers on benefits, IT, code of conduct.

Agentic Handler to Domain Routing

Why this is agentic, not a chatbot: A chatbot retrieves and responds. ASK understands intent, decomposes cross-domain queries, routes to specialised agents in parallel, maintains state across turns, gates on confidence, and escalates with full context to all invisibly to the user.

Domain Classification Flow
  1. User query received → Supervisor agent runs intent classification
  2. Confidence scored per domain (HR / IT / Finance / Cross-domain)
  3. Below 0.65 confidence on primary domain → clarification node: one targeted question to resolve ambiguity
  4. Above 0.65 → route to domain agent(s). Cross-domain queries dispatched in parallel
  5. Domain agent retrieves from its dedicated vector store (RBAC-filtered per user's department)
  6. Vertex AI cross-encoder re-ranks retrieved chunks · LLM generates response
  7. Response delivered · feedback collected · RLHF loop updates document ranking

Why RAG over fine-tuning: HR/IT/Finance knowledge bases update continuously to new policies, org changes, compliance updates. Fine-tuning requires 2 to 3 week retraining + validation per update. RAG updates in hours. Knowledge currency beats marginal accuracy gain from fine-tuning for this use case.

Human Handover Design
TriggerThresholdBehaviourRationale
Low domain confidence0.65Clarification node to one targeted question to resolve ambiguity firstBetter to clarify than confidently answer wrong. False confidence is the worst failure mode.
Low confidence after clarification<0.65Human handover with full query + context + agent path exportedHuman agent never starts cold to they see everything ASK tried
Policy exception request to Direct route to HR/IT manager · flagged as exceptionKeeps high-judgment decisions with humans. ASK handles volume.
PII or complaint detected to Immediate human route + flagged in audit logRisk mitigation. Sensitive queries never auto-resolved.
Enterprise Layer
RBAC

Active Directory integration. Engineers see engineering policies. Finance sees finance data. Cross-department knowledge is architecturally separated to no accidental leakage.

Audit Logs

Every query logged with: original intent, domain classification, agent path, confidence at each step, response generated, whether human handover was triggered. Full compliance trail.

Plug-in Framework

Standardised agent interface so other teams can build domain agents on ASK infrastructure without owning orchestration. Two additional teams building on the platform.

Zero New Portal

Deployed entirely inside Microsoft Teams to existing auth, existing habit, zero adoption friction. The biggest barrier to enterprise AI adoption is the new login. Eliminated architecturally.
