Reducing the Integration Tax in Legacy Digital Transformations

Digital programs often stall not on new features but on the hidden “integration tax” of connecting them to legacy systems—time, rework, and operational risk that compounds with every bespoke interface. The article explains how tight coupling, data silos, and brittle file/script-based integrations force repeated translation work, pushing integrations onto the critical path and increasing production fragility. It outlines low-disruption patterns—API-first contracts, façade layers, read-optimized data stores, and strangler-style replacement—plus a pragmatic sequence to target the most expensive integrations and operationalize reuse. Tech leaders should treat integration as architecture and governance (not tooling) to regain delivery speed without destabilizing core systems.
