Why Carve-Outs Are Expensive
Financial models predict: 6-12 months, $2-5M. Reality: 12-24 months, $5-15M. Hidden costs: shared service decomposition, data migration, license renegotiation, identity/auth separation, monitoring stack duplication, CI/CD pipeline separation, and team knowledge transfer.
The most expensive surprise: shared databases. Separating a shared database takes 6-12 months and costs $1-3M alone.
