Cognizant emphasizes security controls, auditability, and data quality gates within its program delivery governance so audit log expectations align with cutover readiness and structured testing.
What tradeoff occurs when an ERP modernization program prioritizes rapid workflow automation over detailed fit-gap analysis?
Deloitte’s engagements connect fit-gap analysis outputs to functional and technical specifications for audit-friendly alignment, which protects change scope even when multiple workstreams run in parallel. When workflow automation is prioritized without that fit-gap-to-spec traceability, providers like Intellectsoft and Elinext can still deliver automation, but teams risk later rework because automation logic may diverge from requirements traceability artifacts.
