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
