Set goals and scope
- Write down the business problems you expect the ERP to solve.
- Choose a first release that delivers value without trying to do everything.
- Assign an executive sponsor and a full-time project lead.
Map current and target processes
Document how order-to-cash, procure-to-pay and hire-to-retire work today. Decide where to adopt the standard process instead of customizing.
Prepare and migrate data
- Cleanse customers, vendors, items and opening balances.
- Do at least two trial migrations before the real one.
- Reconcile totals after each trial.
Configure and extend
- Configure before you customize.
- Keep extensions isolated so upgrades do not break them.
- Document every deviation from the standard.
Test with real scenarios
- End-to-end tests of each core process.
- Role and permission tests.
- Performance test with realistic volumes.
Train and cut over
- Role-based training close to go-live.
- A defined cut-over plan with a rollback option.
- Extra support during the first close.
Stabilize and expand
Track issues, tune the configuration, and only then add the next module or entity.
