Greenfield & Brownfield Projects

New builds and system conversions — including S/4HANA journeys that protect what works and fix what doesn't.

The greenfield-versus-brownfield question has no universal answer. A clean reimplementation buys you simplicity at the price of disruption; a system conversion preserves your history at the price of carrying old decisions forward. We help you choose on evidence, then deliver either path.

For S/4HANA journeys specifically, we assess your custom code, data volumes, process debt and business appetite before recommending a route — and we will tell you if the honest answer is a hybrid, selective approach.

Our approach

  • Assessment decides the route. Custom-code analysis, data profiling and process-debt review pick the path on evidence.
  • Greenfield: design freedom used deliberately. Standard-first design, clean master data, only justified customisation.
  • Brownfield: conversion without carry-over. We use the conversion to retire dead code and clean data along the way.
  • Business continuity throughout. Month-end still closes, orders still ship, payroll still runs — through every phase.

Typical engagements

  • Greenfield S/4HANA implementations for growing enterprises
  • Brownfield ECC-to-S/4HANA system conversions
  • Selective data transition projects combining both approaches
  • New-entity builds inside an existing corporate template

What you can expect

  • A defensible route decision with the trade-offs documented
  • A landscape ready for the 2030 ECC maintenance horizon
  • Less custom code and cleaner data than you started with
