A process map gives configuration a reason. It explains which business event starts the work, which record carries it forward and which person is responsible when the normal path changes.
Map records, not departments
Department diagrams show reporting structure, but ERP configuration follows records. Map how a lead becomes a quotation, how a purchase request becomes a bill or how an attendance record becomes a payroll input.
For each step, identify the source record, the decision made and the next record created. This reveals where information is copied into spreadsheets, messages or disconnected applications.
Document the exception path
The standard path is usually easy. Returns, partial receipts, rejected expenses, price changes and cancelled orders determine whether the configured system can support daily reality.
- Mark who can approve, reverse or delete a record.
- Note which supporting documents must remain attached.
- Define how the team knows an exception is resolved.
Convert the map into acceptance tests
Each important path should become a short test with an expected outcome. A receiving test, for example, can confirm the purchase order balance, received quantity, warehouse stock and supplier obligation after a partial delivery.
These tests create a shared language between business owners and implementation teams and remain useful when processes change later.
