  • Match delivery model to workload volume and migration waves

    For multi-application programs that require repeated migration waves, Accenture fits well because it uses a cloud migration factory model with standardized accelerators. For similarly industrialized migration governance with standardized wave execution, Cognizant provides a comparable cloud modernization factory model. For enterprises that need migration factory delivery paired directly with target operating model design, Deloitte is built for large multi-app estates.

  • Define governance and security integration requirements early

    If the organization needs governance and security controls embedded during modernization engineering, Capgemini supports production readiness by integrating operational governance and security controls into delivery. If hybrid governance across architecture and ongoing optimization is required, IBM Consulting provides hybrid cloud operating model and governance integration across migration and continued optimization. If security controls must be built into the DevSecOps operating model, Tata Consultancy Services focuses on security-by-design and DevSecOps integration.

  • Choose the modernization engineering depth based on target architecture

    For programs that demand re-architecting and containerization approaches, Capgemini provides deep engineering for re-architecting, containerization, and cloud-native builds. For legacy app modernization that needs end-to-end capabilities from rehosting through refactoring and cloud-native operations, Cognizant delivers rehosting, replatforming, and refactoring toward containerized architectures. For enterprises seeking application modernization factories that deliver refactoring waves with standardized engineering and tooling, Wipro supports structured delivery management with cross-functional engineering teams.

  • Demand operating-model and CI CD enablement tied to release reliability

Common Mistakes to Avoid

Common pitfalls across major modernization providers occur when teams select the wrong engagement shape for their scope, or when they assume governance and readiness will be handled after engineering is complete.

  • Choosing a provider without a migration factory model for multi-app wave plans

    For large multi-wave migrations, Accenture and Cognizant industrialize delivery with repeated waves and standardized accelerators. Deloitte also combines migration factory delivery with operating-model design, which reduces governance drift across many application migrations.

  • Treating governance and security as a separate phase from engineering

    Capgemini embeds cloud governance and security controls into modernization delivery so production readiness is addressed during implementation. IBM Consulting integrates governance into hybrid operating model design and ongoing optimization, which prevents late-stage compliance fixes.

  • Underestimating operating-model readiness work for DevSecOps and release reliability

    Deloitte provides DevSecOps enablement including secure CI CD and automated controls tied to release and reliability engineering support. Tata Consultancy Services emphasizes security-by-design and DevSecOps operating models with cloud controls integrated into delivery.

  • Requesting go-live without demanding runbook readiness and post go-live stabilization

    NTT DATA connects modernization roadmaps to operational runbooks and managed run support after migration. DXC Technology focuses on end-to-end delivery that includes security and runbook readiness artifacts to stabilize workloads after transformation.
