Key Considerations

Hidden ECC Costs

  • Increasing third-party support premiums (17-22% annually)
  • Skills scarcity driving up contractor rates
  • Technical debt accumulation
  • Security compliance gaps and audit risk
  • Integration challenges with modern systems

S/4HANA Value Drivers

  • Reduced infrastructure footprint with HANA
  • Simplified data model reduces storage costs
  • Process automation through embedded intelligence
  • Faster close cycles and real-time analytics
  • Modern UX improves productivity
