Failing to plan for legacy modernization discovery and extensive architecture work
IBM Consulting flags that legacy modernization can require extensive discovery and architecture work. Tata Consultancy Services also indicates that large estate modernization depends on tightly defined scope and governance, which reduces value if discovery and governance are not planned.
Selecting a provider without explicit sustainment-ready release, testing, and quality controls
Infosys builds structured delivery governance that includes test automation, quality controls, and release management, which supports continuity after launch. Providers that focus heavily on transformation without sustainment mechanics can increase the burden on the client during operational transition.
