Modernization: Taming the legacy and keeping the new house clean
summary
Modernization focuses on a thin slice: a bill‑payments journey carved out from a monolithic estate and put into production to prove feasibility. Teams assemble cross‑functional members, use a BFF back end for front end pattern and reduce scope to two services only, deferring costly choices by hard‑code integrations until API available and introducing small corruption layers for legacy. Examples include swaps to MarkLogic, MongoDB and REST APIs; outcome is a working production slice that preserves team autonomy and exposes remaining legacy risks.
