GMP consultant

GMP consultant: GMP expert for validation, audits and inspections

A GMP expert (SME expert) handles qualification, validation, computer system validation, GxP audits, inspection readiness and GMP documentation when in-house capacity or expertise is lacking. A&O's specialists work under GMP themselves, with our own manufacturing authorisation and GMP-certified laboratory in Itzehoe.

At A&O Pharma

How we work with you.

Single project

For a single project

We take on a defined project: qualification of equipment and rooms from DQ to PQ, process and cleaning validation, analytical method validation, computer system validation or a manufacturing transfer. Preparation for a GMP inspection and responses to audit findings can be commissioned in the same way.

Ongoing

Ongoing external QA support

We work within your quality system, for example on CAPA, deviations, change control, complaints, self-inspections and PQR, or help to set up a quality management system. This includes documents such as SOPs, the Site Master File and CMC documentation. If a position in quality assurance is vacant, our interim management is also an option.

Suppliers and service providers

GxP audits and supplier qualification

We audit suppliers and service providers against GMP, GDP or GCP and support supplier qualification. The report gives you the basis for the assessment which, under Chapter 7, rests with you as the contract giver.

Process

How we get started.

  1. Initial call

    You describe the occasion and timeframe, such as an upcoming inspection, a project or an audit. We get back to you within 1 to 2 days.

  2. Offer and contract

    Scope, schedule and responsibilities are set out in a written contract, as required by Chapter 7 of the EU GMP Guide and Section 9 AMWHV.

  3. Execution

    Risk assessment, protocols, execution and reports. Review and approval stay with you.

  4. Completion

    You receive the report and documents. On request we accompany the inspection and the responses to findings.

What the law requires

Legal basis

Anyone who manufactures medicinal products commercially or professionally needs a manufacturing authorisation under section 13 of the German Medicinal Products Act (AMG). Section 3 of the German Medicinal Products and Active Substances Manufacturing Ordinance (AMWHV) refers to the EU GMP Guide. Wholesale distribution is governed by the EU Guidelines on Good Distribution Practice (GDP), which likewise require self-inspections, supplier qualification and validated systems. GMP, GDP and GCP are often grouped together under the term GxP.

What a consultant may take on and what stays with the manufacturer

Chapter 2 of the Guide requires consultants to have adequate education, training and experience for the subject they advise on. Under Chapter 7 and section 9 AMWHV, every outsourced activity needs a written contract.

  • A consultant may prepare protocols and documents, carry out qualification and validation, and conduct audits.

  • The manufacturer remains responsible for the pharmaceutical quality system and for reviewing and approving protocols supplied by a third party (Annex 15, point 2.6).

  • Batch certification remains with the Qualified Person under section 14 AMG.

Qualification and validation under Annex 15

The validation master plan defines the programme. Qualification runs from user requirements (URS) through DQ, factory acceptance testing (FAT) and site acceptance testing (SAT), IQ, OQ and PQ. Process and cleaning validation, validation of analytical test methods and change control follow. Scope and depth follow a documented risk assessment. Retrospective validation is no longer considered acceptable.

Computer system validation and data integrity

Under Annex 11, applications must be validated and IT infrastructure qualified. A risk assessment determines the extent of validation and of data integrity controls. Requirements include a system inventory, access controls, audit trails that are regularly reviewed and periodic evaluation of whether a system remains validated. Drafts of a revised Annex 11, a revised Chapter 4 and a new Annex 22 on artificial intelligence were open for consultation from July to October 2025.

GMP documentation, self-inspection and regulatory inspection

Chapter 4 distinguishes instructions such as specifications and SOPs from records. In addition there is the Site Master File. Under Chapter 9, self-inspections must follow a pre-arranged programme and be recorded, and independent audits by external experts may also be useful. Under section 64 AMG, sites holding a manufacturing or import authorisation are generally inspected by the competent authority every two years.

Weighing it up

External via A&O or hire your own?

External via A&O PharmaHire your own person
Availability At short notice for a project or phase, without a recruitment process. Available only after recruitment and induction, then permanently on site.
Breadth of expertise Access to several specialists, for example for qualification, computer system validation and audits. One person covers what they know themselves.
Knowledge of your site Needs time to become familiar with your equipment, processes and systems. Knows the equipment, processes and contacts from day-to-day work.
Outside view Looks at processes without the blind spots of routine. Chapter 9 names independent audits by external experts as useful. Knows why processes are set up as they are, but more easily overlooks what has become routine.
Responsibility Works to a written contract. The quality system and approvals remain with you. Can hold roles in your quality system on a permanent basis.
Cost Incurred only for the agreed service. With consistently high demand, a permanent position may be more economical. Fixed staff costs, including in periods with little project work.

Frequently asked questions

What we are often asked.

What does a GMP consultant do?

A GMP consultant helps manufacturers meet the requirements of Good Manufacturing Practice, for example in qualification, validation, audits, inspection readiness and documentation. The consultant works to a written contract, while responsibility for the quality system stays with the manufacturer.

What is the difference between GMP and GxP?

GMP is Good Manufacturing Practice. GxP groups several good practices together, including GMP, Good Distribution Practice (GDP) for storage and transport and Good Clinical Practice (GCP) for clinical trials. GxP consulting therefore usually covers more than manufacturing.

What do DQ, IQ, OQ and PQ mean?

Design qualification (DQ) shows that the design meets the user requirements and GMP, installation qualification (IQ) that the equipment is installed correctly. Operational qualification (OQ) shows that it performs as intended across its operating range, performance qualification (PQ) that it works effectively and reproducibly in the process.

What does GxP-compliant data processing and computer system validation involve?

Computer system validation is documented evidence that a computerised system reliably does its job. Annex 11 requires a risk assessment that also takes data integrity into account, access controls, regularly reviewed audit trails, data back-up and periodic evaluation. A&O validates computerised systems in its own laboratory in Itzehoe.

May an external service provider prepare validation protocols?

Yes. Under Annex 15, protocols supplied by a third party must be checked by the responsible personnel at the manufacturing site for suitability and compliance with internal procedures before approval.

How do you prepare for a GMP inspection?

A self-inspection or audit is the usual starting point, covering documentation, open deviations and CAPA, the status of qualification and validation, computerised systems and the control of outsourced activities. After the inspection come the responses to the findings with an action plan.

How often does the authority inspect a manufacturing site?

Under section 64 AMG, sites holding an authorisation under section 13 or section 72 AMG are generally inspected every two years. Unannounced inspections are provided for in particular where counterfeiting or serious defects are suspected.

May a self-inspection be carried out externally?

Chapter 9 of the EU GMP Guide provides for self-inspections to be carried out independently and in detail by designated competent persons from the company. Independent audits by external experts may also be useful. Every self-inspection must be recorded with its observations and actions.
