Business Requirements Delivery — CZ-NST-2026-04-001

Every Nesto requirement
delivered by the platform

This document maps each of Nesto’s seven Worker Onboarding Portal requirements to the Nexus component that fulfils it. No gaps. No custom-code workarounds.

7/7
Requirements covered by the platform — no gaps

Platform components: Nexus + deltaPrism + Chameleon + Atlas

Developer sprints needed per compliance rule change

Nesto’s Worker Onboarding Portal requires automated multi-jurisdiction compliance, RBAC approval gates, a tamper-proof audit trail, and two white-label portals — without ongoing engineering spend for each regulatory change. Every one of those requirements is delivered by four platform components: Nexus (pipeline orchestration — this is the platform name), deltaPrism (data governance and audit), Chameleon (white-label portals), and Atlas (intelligence and document understanding layer). Compliance branches, document validation rules, and regulatory API endpoints are all pipeline configuration. When Gulf regulators update their requirements, Nesto updates a config file. No developer. No sprint. No release.

Atlas Strategic Position: Atlas is the intelligence layer above Wormwood, deltaPrism, and Chameleon. It does not replace any component — it adds capabilities that belong above the pipeline: document understanding at scale, cross-record consistency enforcement, exception explanation, CV pre-qualification before pipeline entry, evidence pack assembly for regulatory inspection, and SuccessFactors handoff integrity gate. Atlas observes the entire pipeline, extracts meaning from documents, flags inconsistencies, and generates intelligence outputs the other components rely on but cannot produce themselves.

R-06Worker Self-Service PortalChameleonWorker uploads, document status, read-only access.
R-07Regulatory API integrationNexus pipeline configEndpoint, auth, and payload format are config. Change takes minutes, not a sprint.
Atlas — Intelligence Layer (7 capabilities included): (1) Document OCR with field extraction and confidence scoring; (2) Cross-document consistency checking across worker file; (3) Exception identification and persona-based routing; (4) Operator readiness narratives for HR dashboards; (5) Evidence pack assembly for regulatory inspection; (6) SuccessFactors handoff integrity gate; (7) CV pre-screening API for candidate eligibility evaluation. Full capability specification documented in Nesto commercial pack (ATLAS_FIT.html, DOC-009).

02 — Multi-Jurisdiction Coverage

MoHRE
UAE — employer side
Nexus rules
Worker registration, contract attestation. Endpoint config, not code. MoHRE has changed its API 3× in 18 months.
eMigrate
India
Nexus rules
ECR-category clearance. India branch activates automatically on Nationality = IN.
FEIMS
Philippines
Nexus rules
OEC issuance, employer accreditation. Philippines branch — no custom code per regulatory body.
POLO
Philippines pre-departure
Human Gate
Conditional gate fires only when Nationality = PH. Configurable — no engineering involvement.
Internal Audit
All jurisdictions
deltaPrism
HR gate + document retention. Evidence export from deltaPrism — no manual assembly required.

03 — The Most Efficient Path

"No code" does not mean zero effort. Configuration changes still require internal resources. When a regulatory body updates its requirements, someone on Nesto’s team must update the config file and test the change. The efficiency gain is that this work takes hours, not weeks — and requires no developer sprint, no release cycle, and no ongoing vendor dependency.

Building a multi-jurisdiction compliance system from scratch requires three parallel engineering projects: a rule engine, an audit system with Gulf-standard immutability and evidence export, and two white-label portals. Every regulatory change requires a developer sprint. Every new jurisdiction requires code changes, testing, and deployment.

The platform delivers all of this on day one — rule engine (Nexus), audit log (deltaPrism), both portals (Chameleon), and intelligence layer (Atlas). Atlas handles document understanding, cross-record consistency, exception routing, evidence assembly, and SuccessFactors integrity gates. Regulatory changes become config file updates. New jurisdictions become new pipeline branches. Nesto’s team owns the configuration, not a development partner.

Approximate Cost Avoidance — First 12 Months

Engineering capacity (if building yourself)
  • Rule engine + audit system + two portals: ~$180,000–$240,000 (6–9 months, mid-market rates)1
  • Ongoing maintenance + regulatory updates: ~$60,000–$90,000/year (1.5–2 FTE equivalent)2
  • Atlas equivalent build: ~$250,000–$500,000 (OCR + consistency checking + exception routing + evidence assembly + SuccessFactors gate + CV screening API + operator narratives)3
Platform approach
  • Implementation (Phase 1): Fixed-price delivery — embedded engineer on-site, full knowledge transfer4
  • Ongoing platform licence: Included — all components, platform support/maintenance, up to 6 regulatory config changes/year4
  • Atlas (all 7 capabilities): Included — document intelligence, consistency checking, exception routing, evidence assembly, SuccessFactors gate, CV screening4

Disclaimer: Estimated costs are approximate and vary by region, vendor rates, and project scope. Development partner rates may differ significantly from market averages. The comparison illustrates the efficiency advantage of a platform approach, not a precise cost guarantee.

04 — Delivery Model & Exit

Phase 1 — Implementation
Embedded engineer on-site
Platform configuration, portal setup, jurisdiction rule build-out, and go-live. Full knowledge transfer to Nesto’s team at Phase 1 close. No outsourced dependency after handover.
Ongoing — Platform Support
SLA-backed from month 7

Priority incident response. Up to six regulatory config changes per year included. Additional capacity available on request. Nesto retains full operational control.

What's included: Platform support and maintenance (infrastructure, security patches, core feature updates). Service desk support (user training, how-to questions, operational guidance) is separate, optional, and recommended from a service ticket perspective.

IP & Exit
Clean exit guaranteed
90-day notice. Full data export in open format within 30 days. Pipeline definitions and config files are Nesto work product — fully portable. England & Wales governing law.
