# OCI Deal Accelerator — Business Case
# Demo: PharmaCorp Mexico — ExaCS migration from on-prem Exadata X6
# Follows exact schema expected by oci_bizcase_gen.py

business_case:
  customer_name: "PharmaCorp Mexico"
  prepared_by: "Carlos Mendoza — Solutions Architect"
  date: "2026-04-12"

  executive_summary: >
    PharmaCorp Mexico operates 3 mission-critical Oracle databases (EBS R12, SAP, DW)
    on aging Exadata X6 hardware. The hardware refresh quote is $1.8M and locks the
    company into 5 more years of on-prem operations with no DR capability. Migration
    to OCI ExaCS X11M reduces annual infrastructure costs by 61% ($1.75M over 3 years),
    adds cross-region DR (RPO<15min, RTO<1h), and resolves the pending SOX audit
    finding on automated patching.

  drivers:
    primary: "hardware_refresh_avoidance"
    urgency: "HW refresh due in 6 months — must decide now or commit $1.8M"
    cost_of_inaction:
      financial: "$2.88M over 3yr: $1.8M HW refresh + $300K/yr support + $80K/yr DC costs"
      operational: "No DR today — single site, single point of failure for EBS production"
      strategic: "SOX audit finding pending: manual quarterly patching is non-compliant"

    notes: >
      ROI based on 3-year TCO comparison. 1-month payback driven by immediate
      elimination of HW refresh commitment ($1.8M avoided). Conservative — does
      not include productivity gains from automated patching or DR risk reduction.

  risks:
    migration_risks:
      - risk: "EBS R12 customizations may require OS-level changes post-migration"
        probability: "Medium"
        impact: "Medium"
        mitigation: "Inventory all customizations pre-migration; test in Pre-Prod"

      - risk: "FastConnect provisioning delay (partner-dependent)"
        probability: "Medium"
        impact: "Low"
        mitigation: "Start in Phase 1 week 1; IPSec VPN as interim backup"

      - risk: "HW refresh deadline pressure (6 months)"
        probability: "High"
        impact: "High"
        mitigation: "16-week migration plan fits within window with margin"

    do_nothing_risks:
      - risk: "No DR — single site, single point of failure for EBS production"
        probability: "High"
        impact: "Critical"
        mitigation: "Cannot be mitigated without infrastructure investment"

      - risk: "SOX audit finding remains unresolved (manual patching)"
        probability: "High"
        impact: "High"
        mitigation: "Remediation requires automated patching — on-prem can't deliver"

      - risk: "$1.8M HW refresh locks in 5 more years of on-prem with no cloud ROI"
        probability: "High"
        impact: "High"
        mitigation: "Sunk cost — delays any cloud migration benefit for 5+ years"

  recommendation:
    summary: >
      Proceed with OCI ExaCS migration. 61% cost reduction over 3 years ($1.75M saved),
      cross-region DR capability, and SOX compliance resolution. The alternative
      (HW refresh at $1.8M) costs more and leaves DR + compliance gaps unresolved.
