Custom ERP vs Off-the-Shelf ERP: A Decision Framework
Choose the boundary that must be unique before choosing an ERP product.
Decision boundary
Choose the boundary that must be unique before choosing an ERP product.
Do not begin with a screen list or a vendor promise. Define the operating decision, the data that proves it and the person responsible for exceptions.
Requirements to confirm
- Map the workflows that create orders, stock and approvals
- List integrations that cannot be handled by a standard connector
- Define who owns master data and exception decisions
Common mistake
Treating a workflow as a set of fields usually creates a system that looks complete but cannot explain ownership, exceptions or acceptance. Keep each rule testable with representative records and real job roles.
How to start
Start with one bounded workflow, document assumptions and acceptance evidence, then expand after the first milestone is operated safely. See the related service and illustrative scope。
