Modernization
A new ERP arrives: what to do with your own systems
When a company implements NetSuite or SAP, its in-house systems do not disappear on their own. Each one needs a decision.
Four paths
Retire, absorb, extend or rebuild
Retire
The ERP fully covers the function: the in-house system is switched off with its data migrated.
Absorb
The ERP covers the function with adjustments: rules and data move into the ERP.
Extend
The ERP covers the core and the in-house system keeps what makes it different, integrated with it.
Rebuild
The function does not fit in the ERP: it is rebuilt on current technology with its specification.
How to decide
With evidence, not assumptions
A measured sample of the most critical screens turns each system into a verifiable specification and shows what the ERP covers and what it does not.
For ERP implementers
For NetSuite and SAP implementers
If you implement NetSuite or SAP and your client has in-house systems the ERP does not cover, we invite you to work with SISCON on that part: we document the system, migrate the data and rebuild or extend what the ERP leaves out, while your team focuses on the implementation.
Frequently asked questions
How do I know which of the four paths fits?
It depends on how much of the system's real function the ERP covers. The measured sample makes it visible before deciding.
Do you work with the ERP implementer?
Yes, we are open to working with whoever implements the ERP on what the ERP does not cover.
Does operation stop?
No. Cutover is route-based and reversible.
Next step
Start with a measured sample: 5 to 10 screens of your system turned into a verifiable specification, with tests and an inventory of differences.
