Scenario‑Based Vendor Evaluation and Readiness Tests for Utility Voice AI
A practical, scenario-driven framework to evaluate Voice AI vendors, scope integrations, run readiness tests, and assign operational accountability for outage and service-request workflows in utilities.
1. Purpose, scope, and audience
This framework is for utility leaders evaluating Voice AI for customer‑service, outage communications, service requests, and field‑service routing. It focuses on procurement, vendor evaluation, phased rollout, scenario-based readiness tests, and accountable operational controls.
Scope and intended outcomes
Targeted outcomes for procurement and rollout: validate account-safe behaviors (no unauthorized account changes), ensure verified status responses (outage and restoration), guarantee safe escalation for ambiguous or safety‑sensitive calls, and produce measurable acceptance criteria for phased deployment.
- Operational reliability for outage and service-request workflows
- Integration safeguards with OMS/CIS/CRM/field systems via approved APIs
- Clear human escalation and runbooks for failure modes
Who should use this framework
Primary users include customer-service managers, outage communications leads, operations and field-service supervisors, IT/integration architects, procurement, and regulatory/compliance officers. Each group should own specific deliverables in the procurement and testing phases.
- Procurement: SLA, artifacts, security evidence
- IT/Integration: API contracts, adapters, test harnesses
- Operations/Field: routing, scheduling, technician handoffs
2. Canonical architecture and failure boundaries
Agree a canonical call flow and explicit failure boundaries before vendor selection. That shared architecture defines what Voice AI is authorized to do and what always must route to humans.
Canonical call flow (decision model)
Define a single, auditable call flow that every vendor must demonstrate: Caller → Voice AI front-end → Account/location validation → Approved utility API / knowledge source → Action: status response OR service-request creation OR human escalation. All steps must be instrumented with event identifiers.
- Front-end IVR or call-handling system hands session to Voice AI
- Voice AI performs account or premise validation using approved APIs or tokenized lookup
- If validated, Voice AI fetches authoritative data (outage status, service history) from utility systems via controlled adapters
- Action outcomes: automated response (non-critical), create or update service-request, or escalate to human agent
Failure boundaries and safe defaults
Explicitly document failure modes and the default response for each. Safe defaults must bias toward human involvement for ambiguous, safety‑sensitive, or account‑change requests. Use documented thresholds for containment vs. escalation.
- Unknown or partial validation → escalate to agent
- Conflicting data from authoritative sources → pause automation, notify ops and escalate
- Integration timeout or API error → retry policy then escalate
- High-risk phrases (e.g., 'gas leak', 'electrical fire') → immediate human escalation and emergency guidance
3. Vendor evaluation criteria and procurement checklist
Procurement must be outcome‑focused and testable. Move beyond feature checklists to required artifacts, tests, and evidence of operational maturity.
Integration, data contracts, and APIs
Require vendors to demonstrate adapters that call only approved APIs and adhere to a signed data contract. Tests should prove the end‑to‑end path from Voice AI to the utility system and back, including error injection and reconciliation.
- Signed data contracts showing fields, validation rules, and error codes
- Sandbox endpoints for OMS/CIS/CRM with replayable test records
- Tokenized or delegated credentials (no hard-coded service accounts)
Operational controls, SLAs, and surge capacity
Ask for measurable SLAs tied to service outcomes: containment rate, escalation latency, success rate for service‑request creation, and surge capacity guarantees. Include phased rollback or throttling mechanisms for event spikes.
- Containment and escalation metrics with sample dashboards
- Defined surge modes and capacity commitments during large outages
- Runbook commitments for failover, degraded modes, and manual overrides
Security and privacy evidence
Require third‑party evidence: ISO/IEC 27001 and ISO/IEC 27701 alignment or equivalent attestations, subprocessors list, and data‑residency plans (hosting region, backup region, cross‑border transfers). Vendors should document remote-support access, retention policies for recordings, and breach notification duties.
- ISO 27001 and ISO 27701 certifications or gap remediations
- Subprocessor inventory and transfer mechanisms
- Policies for recording consent and retention aligned with law and utility policy
4. Scenario‑based readiness tests and phased rollout
Design tests that reflect high‑impact, real‑world scenarios: multi‑premise outages, ambiguous account data, language and accessibility variations, surge volumes, and field‑service scheduling handoffs.
Outage communications scenarios
Run scripted scenarios that exercise upstream and downstream dependencies. Validate that Voice AI accurately reports outage status, estimates, and restoration messaging, and that it escalates when authoritative data is inconsistent or unavailable.
- Single-premise flicker vs. feeder-level outage simulation
- Conflicting OMS vs. customer report: ensure escalation and logging
- Mass outage surge test: measure containment, queueing, and escalation rates
Service‑request and field‑service routing tests
Validate full lifecycle: caller intent capture → location/account validation → create SR with correct priority and attachments → dispatch handoff to field systems → technician acknowledgment and status updates. Test misrouted SRs and reassignments.
- End‑to‑end SR creation and reconciliation with field‑service system
- Test for missing or ambiguous address data and safe escalation
- Confirm read/write permissions and audit trails for SR changes
Acceptance gates for phased rollout
Apply go/no‑go gates between phases based on measurable KPIs: containment threshold, false‑positive rate for automated actions, escalation latency, and system availability. Require remediation plans before advancing.
- Phase 1: limited pilot with scripted scenarios and live supervised calls
- Phase 2: targeted rollout to specific feeder/region with performance SLAs
- Phase 3: enterprise rollout with continuous monitoring and periodic audits
5. Operational runbooks, escalation and accountability
Operational playbooks translate contract terms and tests into day‑to‑day behavior. Define human roles, escalation triggers, and evidence capture for audits and regulators.
Human‑in‑loop escalation and routing
Define the precise triggers that route to agents, supervisors, or emergency services. Ensure voice sessions include session IDs, event-level logs, and handoff transcripts for audit and quality assurance.
- Escalation triggers: validation failures, safety keywords, data conflicts, retry exhaustion
- Agent handoff payload: account token, call transcript, last validated data, recommended action
- Supervisor alerts for repeated failures or systemic degradations
Incident response and business continuity
Maintain incident runbooks that coordinate vendor and utility actions during degradations: distinguishing partial functional loss (e.g., read-only status) from full loss (no access to APIs). Define notification timelines and stakeholder responsibilities.
- Immediate containment steps and manual fallback workflows
- Escalation matrix for technical, security, and regulatory incidents
- Post-incident analysis: root cause, mitigations, and acceptance criteria to resume automation
6. Measurement, observability, and acceptance criteria
Acceptance and operational control depend on event‑level telemetry. Specify the metrics, dashboards, and audit artifacts required for acceptance and ongoing governance.
KPIs and event‑level analytics
Require vendors to expose event streams for each call with standardized fields (session ID, validation outcome, authoritative data version, action taken, escalation reason). Define dashboards and alerts for containment, escalation latency, SR accuracy, and error rates.
- Containment rate: percent of calls resolved without human agent
- Escalation latency: time from trigger to agent pickup
- SR success ratio: created SRs that reconcile with field‑service records
Acceptance tests and go‑live metrics
Acceptance criteria should be quantitative and timebound. Require vendors to meet these thresholds in a representative live window before full deployment and to provide continuous evidence post‑go‑live.
- Pre-go-live: 7‑day live supervised window with defined KPI thresholds
- Post-go-live: 30‑day stability reporting and weekly health checks
- Regular audits: integration tests, security posture reviews, and privacy impact assessments
7. Procurement deliverables and RACI for rollout
Translate the framework into contract deliverables and a RACI. Vendors must deliver reproducible test artifacts and the utility must own acceptance gates and operational controls.
Required contract artifacts
List the minimum artifacts to request and accept during procurement and rollout. Each artifact should be verifiable by the utility in a sandbox environment.
- Signed data contracts and API test suite with sample payloads
- Integration test reports, runbooks, and playbooks for degradations
- Subprocessor list, hosting regions, retention and access policies, and evidence of certifications
Roles, RACI and phased responsibilities
Create a RACI that assigns responsibility for test execution, go/no‑go decisions, runbook updates, and post‑incident remediation. The utility must retain final authority over escalation rules and account validation logic.
- R: Vendor — build adapters, deliver test harness, operate managed service
- A: Utility — acceptance gates, go/no‑go decisions, escalation policy ownership
- C: Operations/Field — validate SR lifecycle and technician workflows
- I: Regulatory/Legal — review data residency and privacy obligations

Frequently asked questions
Good starting points include billing and account questions, move-in or move-out intake, appointment scheduling, service-request capture, outage-status messaging from approved systems, payment-routing assistance, and structured escalation. Safety-critical and infrastructure-control decisions should remain with qualified utility teams.
Official reference: Cross-Sector Cybersecurity Performance Goals
Use the minimum approved identifiers needed for the workflow, validate them against the utility's system of record, limit data exposure, and provide a human-assisted path when verification fails. The Voice AI should not guess account, premise, or outage information.
