Multi-company ERP programs require a balance between harmonization and local autonomy. Too much standardization can slow down local execution; too much local freedom creates process divergence and maintenance overhead.
The most effective approach defines a non-negotiable global core and controlled local variations. This model improves decision speed and reduces conflict between group-level consistency and local operational requirements.
Recommended global core
- Security model and access principles.
- Key master data standards.
- Group reporting logic and close calendar.
- Change governance process.
Local exceptions should be explicitly justified: legal constraints, market-specific operations, or contractual requirements. Without justification, exceptions become preferences and scale complexity unnecessarily.
A clear RACI is mandatory: who proposes, who validates, who implements, and who supports. In prospect discussions, this governance clarity is often a major trust factor for executive sponsors.
Wave planning should group entities by comparable maturity and complexity. This sequencing enables learning effects and increases rollout speed with each subsequent wave.
