Supplier/Vendor Audits

Supplier & Vendor Audit Services

A Supplier/Vendor Audit seeks to verify physically or on-site at the supplier’s premises, that they are complying with certain criteria. This criteria can be dictated by your organization and may encompass the following but not limited to:

  • A specific ISO or API standard, such as ISO 9001 or API Q2
  • Your organization’s own requirements for Suppliers/Vendors
  • Product specification
  • Procurement requirements

In general, a Supplier/Vendor audit should provide certainty that the Supplier/Vendor has the capability to provide products and/or services to your organization, that meet your own Quality, Environmental, Safety, Information Security, On-Time Delivery, or other requirements as applicable.

Frequently Asked Questions

Yes, starting on April 1, 2020 Mireaux began providing Remote Auditing, which applies to Supplier Audits, however it may only be done partially remotely depending on what the scope of the audit is. Remote Auditing can be done fully remotely or partially, and for Supplier Audits, therefore, the scope of the audit may dictate whether the audit can be done fully remotely or partially on-site.

There are many reasons that can spark the need to conduct a Supplier/Vendor Audit. Among them are the following:

  1. Your organization requires it for Supplier/Vendor approval
  2. Your organization requires it for Supplier/Vendor re-approval
  3. The Supplier/Vendor has shown a negative trend in the number of NCRs (product or service nonconformances)
  4. The Supplier/Vendor has been issued a Corrective Action and you would like to verify implementation and effectiveness
  5. A customer complaint was received, where the root cause was attributed to a failure or breakdown in the supplier/vendor processes
  6. Your organization wants to give the Supplier/Vendor additional work and wants to verify capabilities and capacity
  7. An information security incident, environmental impact, or safety incident occurred and it is evident that an error in the supplier/vendor’s processes, contributed to the problem.

In essence, reasons for conducting a Supplier/Vendor Audit abound. If your organization practices the ISO principle of “Relationship Management” formerly known as “Mutually beneficial Supplier Relationships”, then being able audit your Supplier/Vendor should be welcomed as an opportunity for furthering the ties between you and your supplier/vendor.

The ISO management system standards do not require Suppliers/Vendors Audits as part of the evaluation/reevaluation of supplier or vendors. API however, is more prescriptive in its requirements for Suppliers/Vendors’ initial evaluation and selection, as shown on the following API Q2 excerpt:

The requirement above is clear in that an assessment of the supplier needs to be done at their facility (the facility from where the supplier is providing their product or service); however, the assessment can be conducted by your organization, an organization you outsourced to, or a third-party. Whichever method you decide, it should be part of your supply chain program and be documented as part of your management system requirements.

Audits should never be confrontational or offensive.  If you have a management system in place that follows the ISO principle of “Relationship Management” formerly known as “Mutually beneficial Supplier Relationships”, then the relationship between you and your supplier/vendor should be one of mutual cooperation and improvement.

In general, Mireaux discourages use of surprise audits or similar scare tactics. We like to send Audit Agendas in advance and make sure that the organization is fully aware of our visit. However, if you truly believe that there are major discrepancies that need to be verified, it is up to your organization to bypass early notification and just show up.

Having a management system in place means establishing a process to control suppliers, vendors or external providers. While this process may vary based on the organization, the type of suppliers, or the requirements of the standard it subscribes to; in general it consists of having a program in place to approve and periodically reapprove the supplier. And is here where auditing the supplier could become a great tool to ensure that the approval or re-approval of the supplier is done thoroughly and not from a distance. 

Mireaux Auditors have extensive experience conducting audits and have been at both receiving ends of the Audit spectrum, escorting an Auditor during External Audits, or leading audits themselves.  As an ISO 9001 and ISO 27001 certified company, Mireaux has its own set of standards and procedures that its Associates have to follow. From issuing the Agenda 2 weeks in advance, to providing Audit Reports within 3-days of Audit completion;Mireaux can help your organization verify your supplier/vendor’s management system for the benefit of all.

Mireaux will help find your customized solution!
