Large providers offer different combinations of proprietary tooling, cloud engineering, industry assets, and managed services. A shortlist can misrepresent those differences if it treats every provider as interchangeable or ignores the internal governance burden.

  • Selecting a provider without testing its proprietary tooling against the actual estate

    Require Hexaware to map Amaze and RAPID workflows to the source platforms, target platforms, conversion tasks, and testing scope. Require Cognizant to demonstrate how Skygrade handles dependency mapping and migration wave planning for the identified estate.

  • Assuming a broad delivery framework creates a single control plane

    Ask IBM to identify which Cloud Pak for Data controls and DataStage functions are included in the proposed architecture. Ask Infosys to document ownership across Cobalt, hyperscaler services, enterprise applications, and managed operations.

  • Underestimating governance and decision latency in large programs

    Define architecture authority, escalation paths, regional responsibilities, and cutover approvals before selecting Tata Consultancy Services, Infosys, Deloitte, or Accenture. These providers can support large programs, but each may involve multiple teams and management layers.

  • Treating industry coverage as interchangeable across providers

    Match Capgemini to SAP and mainframe coordination, Deloitte to regulated industry reference architectures, and Genpact to finance, supply chain, and customer operations. Require named specialists for the business domains that determine migration priorities.

  • Ignoring administration and API limitations in the operating model

    Test Wipro's administration controls and API surface during solution design because its service model is less standardized than specialist platforms. Test Genpact's provisioning controls and public API documentation before assigning internal teams to ongoing platform administration.
