Common Mistakes to Avoid
Repeated delivery constraints across providers center on misaligned expectations for governance effort, unclear data ownership, and selecting a delivery model that does not match migration wave complexity.
Assuming governance and documentation do not affect speed
Accenture and Deloitte can produce heavy process and documentation during governed migrations, and that overhead increases when client stakeholders cannot provide validation availability. Capgemini and IBM Consulting also add governance and structured planning steps that can slow down early cycles if target data ownership and acceptance criteria are not clearly assigned.
Not establishing data ownership and access readiness upfront
Multiple providers flag that delivery depends on clear target data ownership and data access readiness, including Capgemini, Wipro, NTT DATA, CGI, and Sopra Steria. When ownership is unclear, mapping acceptance and issue resolution slow down during active migration waves.
Choosing a provider with a wave or factory operating model for a small one-off transfer
Infosys and NTT DATA emphasize multi-system programs with structured waves and cutover execution, which can be excessive for very small one-migration efforts. CGI and Sopra Steria similarly focus on complex program readiness, which can feel process-heavy for small, simple transfers.
Under-scoping reconciliation validation and rollback planning
Delays and defects increase when reconciliation testing and rollback readiness are not treated as core workstreams, which is why Deloitte, Tata Consultancy Services, IBM Consulting, and Wipro embed reconciliation and cutover readiness into their delivery methods. Providers that emphasize operational controls, including IBM Consulting with rollback strategies and CGI with strict cutover readiness controls, directly address go-live risk.
