Direct answer
What is the direct answer?
An ERP requirements checklist should document business processes, roles, approvals, shared data, exceptions, integrations, reports, migration rules, security, and rollout ownership. It should describe how work must operate, not merely list screens or modules.
What should you know first?
- Map current and target processes before selecting modules or software.
- Name the owner, source, validation rule, and retention need for important data.
- Document exceptions and approvals as carefully as the normal workflow.
- Treat migration, training, support, and reporting as core project scope.
Which business processes should the ERP cover?
Start with the cross-team processes that create delays, duplicate entry, weak control, or unreliable reporting. Define the trigger, participants, decisions, outputs, exceptions, and success measure for each process.
A module name such as inventory or procurement is too broad to estimate. A useful requirement explains how a request becomes an approved purchase, how goods are received, how discrepancies are handled, and which records finance needs.
Separate the first release from future improvements. Prioritise workflows that establish dependable shared data or remove a costly operational constraint.
What should be documented for every workflow?
| Requirement | Question to answer | Expected output |
|---|---|---|
| Roles | Who starts, reviews, approves, and audits? | Permission matrix |
| Data | Which fields, sources, and validation rules apply? | Data dictionary |
| Exceptions | What happens when the normal path fails? | Exception map |
| Controls | Which limits, evidence, and separation are required? | Control register |
| Measures | How will speed, quality, and adoption be judged? | Reporting plan |
Which technical requirements are commonly missed?
These requirements shape architecture and delivery risk. Bring them into discovery so the estimate reflects an operable system rather than a demonstration of the happy path.
- →Identity, permissions, audit history, and account recovery
- →Integration ownership, rate limits, retries, reconciliation, and failure alerts
- →Migration cleaning, mapping, test runs, sign-off, and rollback
- →Performance expectations for peak volumes and large reports
- →Backup, recovery, monitoring, support, and supplier exit procedures
How should an ERP rollout be phased?
Phase the rollout around complete operational outcomes, stable master data, and teams that can adopt the change together. Each phase needs acceptance criteria, migration rehearsal, training, support, and a clear fallback.
A phased release reduces risk only when dependencies are explicit. Avoid splitting a single end-to-end process across systems without defining temporary ownership and reconciliation.
FAQ
What do businesses ask most often?
Should we choose an ERP platform before writing requirements?
Usually no. Define the critical processes, controls, integrations, data, and constraints first, then compare how well configurable products and custom development meet them.
Who should contribute to ERP requirements?
Include process owners, representative users, finance, operations, technology, security, and the leaders accountable for adoption and business outcomes.
How detailed should ERP requirements be?
They should be detailed enough to test a workflow, estimate its risk, define acceptance, and expose unresolved rules without prescribing every interface decision too early.
