What are they?

Structured, objective evaluations — conducted by experts who are independent of the activities being assessed

An audit is a systematic, independent and documented process for obtaining evidence and evaluating it objectively in order to determine the extent to which agreed criteria are fulfilled (ISO 19011).

Audits provide organisations with a reliable, evidence-based picture of how processes actually perform — not just how they are documented. When conducted by experienced professionals who have no stake in the outcome, audit findings carry credibility both internally and with customers, regulators and certification bodies.

MBO provides first-party (internal) audits carried out on behalf of the organisation and second-party (supplier / partner) audits on behalf of interested parties — in both cases by consultants who are independent of the function or supplier being audited, ensuring objectivity and professional rigour.

Audit Types

Two distinct audit contexts, one professional approach

ISO 19011 defines three types of audit by party. MBO specialises in the first two — the types where a truly independent auditor adds the greatest value.

First-Party Audit

Also called: Internal Audit

A first-party audit is performed by, or on behalf of, the organisation itself for management review and internal purposes. It assesses the organisation's own processes, systems or procedures against its own requirements, applicable standards or regulatory obligations.

While many organisations perform internal audits with their own staff, using an external independent auditor eliminates familiarity bias, ensures conformance to the applicable standard, and often surfaces issues that internal teams overlook — making findings more credible and action plans more targeted.

First-party audits are a mandatory element of ISO 9001, ISO 14001, ISO 45001, ISO 50001 and other management-system standards. They also serve as an essential preparation tool before external (third-party) certification or surveillance audits.

Second-Party Audit

Also called: Supplier / Customer Audit

A second-party audit is carried out by an organisation — or by someone acting on its behalf — upon its suppliers, subcontractors or other external parties. The primary purpose is to assess whether suppliers meet agreed quality, safety, environmental or contractual requirements before or during a commercial relationship.

Delegating second-party audits to an experienced, independent consultant ensures that findings are credible, technically sound and free from commercial pressures. It is also considerably more cost-effective than developing and maintaining an in-house supplier-audit capability.

Second-party audits are widely required in the automotive, aerospace, food, medical device, construction and defence sectors, and increasingly expected by large organisations throughout their supply chains.

The independence advantage

Why choose an independent auditor?

Independence is not just a procedural formality — it is the foundation of audit credibility and the main determinant of audit value.

An auditor who does not report to the function being audited, has no financial interest in the outcome, and is not embedded in the organisation's culture can provide observations that internal teams simply cannot. Familiarity blindness — the tendency to normalise long-standing practices — is one of the most common reasons that internal audits miss significant nonconformities.

MBO's consultants bring sector-specific technical knowledge, cross-industry benchmarking experience, and an objective external perspective. Findings are documented with the precision required for root-cause analysis and corrective action, not just for ticking a compliance box.

A key principle of ISO 19011: auditors must be impartial and free from conflict of interest. Using a consultant who is independent of both the audited function and of any certification body is the most straightforward way to demonstrate this impartiality.

Where applicable, integrated audits covering multiple ISO management system standards (e.g. ISO 9001 + ISO 14001 + ISO 45001) are conducted in a single visit, maximising efficiency and minimising operational disruption.

Methodology

How an MBO audit is conducted

Our audit process follows the PDCA model described in ISO 19011 and is adapted to the specific type, scope and context of each engagement.

Audit Planning

Scope, objectives and criteria are agreed. Audit programme, checklist and document-review schedule are prepared in advance.

Document Review

Relevant procedures, records, previous audit reports and corrective actions are reviewed before the on-site visit to identify areas requiring focus.

On-Site Audit

Opening meeting → process observation → interviews with process owners → records sampling → evidence gathering. Conducted against agreed criteria.

Findings & Closing Meeting

Nonconformities, observations and opportunities for improvement are presented to management with supporting objective evidence.

Audit Report

A formal written report — structured, graded and referenced — delivered within an agreed timeframe after the audit visit.

Corrective Action Support

Optional guidance on root-cause analysis methods and corrective action planning, with follow-up verification on request.
