Common Mistakes to Avoid
Several selection pitfalls repeat across major ERP integration service providers and can lead to rework, slowed delivery cycles, and unstable interfaces.
Choosing a vendor without the governance model needed for multi-system release coordination
When release orchestration spans ERP, CRM, and custom apps, governance gaps create defects and unstable cutovers. Deloitte and IBM Consulting reduce this risk by providing structured integration program governance, end-to-end test management, and security and identity lifecycle controls.
Treating data migration as a separate task instead of cutover-ready integration preparation
Interfaces fail at go-live when mapping and validation do not support cutover readiness. Accenture focuses on structured ERP program delivery that includes data migration mapping, validation, and cutover planning, while PwC emphasizes reconciliation testing to prevent reporting defects.
Underestimating master data synchronization and ownership for shared records
Order-to-cash and procure-to-pay failures often trace back to inconsistent customer, product, or reference data mapping. Capgemini and NTT DATA address this directly through master data synchronization and master data governance for shared records.
Skipping managed operations planning for post go-live interface monitoring and incident response
Production handover without monitoring makes it harder to stabilize interfaces and control change. Infosys and Tata Consultancy Services provide managed operations and centralized monitoring with security controls for ongoing interface reliability.
