Phase 2: Summary of Approach

Scope & Release Strategy

  • 10 of 12 products are running partial releases (controlled pilots)
  • 2 products (EY Fabric Next & Portal) are full-scope releases
  • 1 product (Risk Radar) runs a simulated full release as a greenfield replay
  • Most pilots target non-prod environments; Tax SL products also include production
  • 8 brownfield (existing products) vs 4 greenfield (new builds or replays)

AI Approach Distribution

  • 5 products take a purely Agentic approach (Assurance, Consulting, EY Parthenon) — orchestrating AI agents with human oversight
  • 2 products use a hybrid model (Risk Radar: Assisted+Agentic; EY Workforce: 60% Agentic / 40% Assisted)
  • 5 products adopt an Assisted approach (Fabric & Tax) — enhancing existing workflows with AI prompts and co-pilots
  • Tax teams (ITTS, EYMP) have aspirational targets to evolve toward orchestration

Estimation & Expected Gains

  • Marketing.AI: 55 → 34 SPs (38% reduction)
  • EY.AI for Risk: 40 → 26 SPs (35% reduction)
  • EY Workforce: 70–100 → 40–60 person-days (~40% reduction)
  • Risk Radar: 9 months → 3 months (67% reduction)
  • Spotfire: 12 months/$1M → ~1 hour per migration (transformational)
  • Several Tax and Fabric products have yet to establish AI-specific ROM baselines

Tooling Landscape

  • Factory.AI — adopted by all 12 products as the primary AI platform
  • GitHub + Copilot — used by 11 of 12 products
  • Figma — used by 10 products
  • Azure DevOps (ADO) — system of record for Consulting and some Tax
  • Playwright — adopted by Consulting for automated QA
  • SonarQube / Artifactory — used by Fabric for quality gates

Program Objectives Alignment

  • Accelerate time-to-market — targeted by 10 of 12 products
  • Enhance software quality & security — targeted by 10 of 12 products
  • Increase efficiency — targeted by 11 of 12 products
  • Reduce total cost of delivery — targeted by 6 of 12 products
  • Enforce compliance — targeted by 7 of 12 products

Team Size by Service Line

  • Tax: 83 people across 4 products (largest SL)
  • Fabric: 70 people across 2 products
  • Consulting: ~13.5 people across 3 products
  • Assurance: ~9 people across 2 products
  • EY Parthenon: TBD (1 product)
