Look for the repeated work.

Different businesses often need similar capabilities: receiving inquiries, managing documents, coordinating work, and reporting activity. Identifying those repeated needs creates a starting point for reusable software.

Share capabilities with clear boundaries.

A common platform does not require every business to share the same data or permissions. Define who owns each record, who may access it, and what an integration is allowed to change. Treat access and confidentiality as part of the design.

Keep business ownership explicit.

Shared technology can support several teams, but accountability should remain clear. An operating business owns its customer relationship and commitments. The platform team owns the agreed technical service. Document that relationship rather than relying on informal assumptions.

Choose reuse where it improves the work.

Reuse introduces maintenance and coordination costs. Start with capabilities that recur frequently and have similar requirements. Measure the value through time saved, fewer repeated steps, and a lower support burden. A specialized workflow may still need its own implementation.

Make the shared platform maintainable.

Version interfaces, document dependencies, and provide a way to recover from a failed change. A holding company gains more from a dependable, understandable platform than from a collection of tightly coupled experiments.
