Why the World Still Runs on SAP

• AI won’t replace SAP/ServiceNow/Salesforce — it wraps them as a new action layer.
• Switching costs are prohibitive; these systems encode compliance, permissions, canonical data.
  • SAP ECC → S/4HANA migration: $700M, 3 years, 50 Accenture staff.
  • Lidl abandoned SAP transition after $500M spent.
• Three phases of opportunity: implementation, usage/maintenance, extensions.
  • Implementation: AI auto-generates field mappings, test scripts, migration playbooks.
  • Usage: copilots + computer-use agents cover last 30–40% of workflows where APIs don’t exist.
  • Extensions: thin apps replace 12-transaction workflows with single intent-driven UI.
• Factor Labs and Sola deploying computer-use agents in production, replacing BPO spend.
• ERP becomes system of record; the AI intent layer becomes the new system of action.
  • Digital workers context-switch ~1,200x/day — 4 hours/week lost to app-hopping.
  • “Describe the outcome, the system gets you there” replaces transaction codes.
• Moat compounds: every workflow → reusable intent, every exception → guardrail.
