ERP Implementation Checklist for Regulated Manufacturers

Implementing an ERP system in a regulated manufacturing environment is not the same as a standard rollout. The system will hold data that carries regulatory and patient risk, so the implementation has to produce not only a working system but the documented evidence that it was specified, built, and tested under control. Microsoft Dynamics 365 Business Central is not compliant out of the box — compliance is achieved through risk-based configuration and computer system validation (CSV) against documented requirements. This checklist walks through what an implementation for a regulated manufacturer has to cover, phase by phase.

How to use this checklist

Work through the phases in order; each one produces evidence the next depends on. The depth of effort per item should follow a risk assessment — a critical, GxP-relevant function (batch release, electronic signatures, audit trail) warrants more rigour than a low-risk report. This is the CSA / risk-based approach that GAMP 5 (Second Edition) expects: validate what matters, and document why the rest matters less.

Phase 1 — Scope and requirements

1. Define the regulatory scope: which regulations apply (EU GMP Annex 11, 21 CFR Part 11, Annex 22 for AI, GAMP 5) and which processes are GxP-relevant.
2. Write a User Requirements Specification (URS), approved by QA, covering functional, data-integrity, security, and regulatory requirements.
3. Perform a GxP risk assessment per process area to set the validation effort (CSA / risk-based).
4. Record the intended use and system boundaries, including integrations (LIMS, QMS, WMS, MES).

Phase 2 — Supplier and system qualification

5. Assess the supplier: for Business Central online, evaluate Microsoft's documented quality and security controls rather than auditing the data centre yourself.
6. Classify the system and its extensions against GAMP 5 software categories.
7. Qualify the infrastructure (or document reliance on the SaaS platform's qualified infrastructure).
8. Confirm the release / update cadence is understood and controlled (SaaS updates are a change-control input, not a surprise).

Phase 3 — Design, configuration, and data integrity

9. Configure the audit trail so that GxP-relevant changes are captured, attributable, and tamper-evident (ALCOA+).
10. Design access control on least-privilege: role-based permissions, segregation of duties, and no shared accounts.
11. Configure electronic signatures where required, with the meaning of the signature recorded.
12. Define data-integrity controls across the record lifecycle — creation, change, archival, and retention.
13. Document every configuration decision so it can be traced to a requirement.

Phase 4 — Validation (IQ / OQ / PQ)

14. Write validation protocols (IQ, OQ, PQ) that trace to the URS.
15. Execute the protocols and retain the executed records with evidence.
16. Log, assess, and close every deviation before release.
17. Produce a Validation Summary Report (VSR), approved by QA, that concludes the system is fit for intended use.
18. Maintain a requirements-to-test traceability matrix.

Phase 5 — Go-live and operations

19. Put change control in place before go-live — no change to the validated system without assessment.
20. Train users and record the training as evidence.
21. Schedule periodic review to confirm the validated state remains current.
22. Define the process for handling SaaS updates under change control (impact assessment, regression testing where warranted).

A checklist is a starting point, not a validation plan. If you are scoping an implementation in a regulated environment, a short advisory conversation can clarify where the real risks are before the project starts.
