Reducing Failure Risk in Application Modernization

Modernization programs often fail not because the technology is wrong, but because delivery is mis-sequenced and poorly governed. The article outlines five common failure modes: starting with tools instead of outcomes, big-bang rewrites, underestimating data/integration dependencies, unclear decision rights, and neglecting change management and operational readiness. It recommends incremental releases tied to metrics, architecture guardrails (security/observability), and continuous risk reduction throughout delivery. Tech leaders can use this to reduce cutover risk and demonstrate value before committing to multi-year migrations.
