Common Mistakes to Avoid

Common failures come from choosing a provider without the delivery governance, engineering depth, or client coordination needed for complex modernization execution.

  • Selecting a provider that cannot support multi-wave release governance

    Organizations that need repeated migration waves with controlled testing and releases should prioritize Accenture or Infosys because both emphasize modernization factories with testing and governance mechanics. Providers without that kind of orchestrated wave model tend to require higher manual coordination across cutovers.

  • Underestimating how governance and operating-model work affects early momentum

    Smaller teams can feel slowed by governance overhead in delivery models like those described for Deloitte, Capgemini, and TCS. Short timelines and small modernization scopes should be paired with clear decision ownership, which Nagarro calls out as required to avoid slow trade-off approvals.

  • Assuming modernization outcomes are independent of discovery and client availability

    IBM Consulting ties modernization outcomes heavily to client availability for legacy app and data discovery, so discovery staffing must be scheduled early. For any program where discovery is not ready, rework risk rises across migration and refactoring planning.

  • Choosing integration and API delivery depth that does not match the modernization approach

    For phased replacement strategies that rely on API and integration modernization, Accenture’s and Cognizant’s emphasis on robust API engineering is a concrete fit. Programs that treat integration as a minor side task can see delayed handoffs because modernization depends on API enablement and integration modernization patterns.
