Training module

Supplier Auditing

Plan and conduct supplier audits using contract-based criteria, defined evidence targets and disciplined audit documentation

Cross-disciplineManagement System Auditor
Supplier auditor discussing evidence and audit criteria with a supplier representative on-site, illustrating supplier audit execution through contract-based requirements and evidence-focused assurance.

Are your supplier audits failing to provide reliable assurance?

Execute disciplined supplier audits with clear criteria, targeted evidence, and robust documentation for defensible and usable results.

Overview

What this module is about

Supplier audits often navigate complex terrain, balancing contractual obligations with operational realities and limited access. Without a structured approach, these audits can devolve into superficial reviews or mere relationship management.

This module provides a professional, evidence-focused methodology for executing supplier audits. Participants will learn to define audit scope and criteria from contractual requirements, prepare specific evidence targets, conduct audits effectively within access boundaries, and produce clear documentation that supports internal use and downstream reporting, ensuring results are defensible and actionable.

Audience

Who it is for

Management system implementers and coordinators

Executives and department heads accountable for management system performance

Those responsible for processes, policies, assets, risks and controls

Auditors seeking insight into management-side practice, not audit technique

Consultants working on management system design, governance or improvement

Decision supportIs this module for you?

It is a good fit if you…

conduct supplier audits under contractual or access constraints.

struggle to define scope, criteria, and evidence expectations upfront.

experience supplier audits drifting into visits or relationship meetings.

need supplier audit results that are defensible and usable internally.

want to run supplier audits professionally under real-world limitations.

It may not be the best fit if you…

already execute supplier audits with clear scope and evidence targets.

are not involved in supplier audits or second-party assurance.

need contract negotiation, procurement, or supplier management training.

are looking for programme governance rather than audit execution.

Agenda

What is taught

8 parts
01Supplier audits as assurance engagements

How supplier audits function as assurance engagements rather than performance discussions, and how purpose, boundaries, and typical constraints such as access, confidentiality, proprietary methods, and subcontractors shape audit execution

02Engagement-level planning

How to turn contracts, SLAs, and mandatory obligations into audit criteria, and define an auditable scope that matches what can realistically be assessed across sites, services, and interfaces

03Preparing supplier-specific evidence targets

How to prepare using available pre-reading materials and build evidence target matrices that align criteria with supplier-specific interfaces and constraints

04Executing supplier audits on-site, remote, or hybrid

How to structure the audit day, maintain control of time and access, and follow key service interfaces end-to-end across handovers, controls, and records

05Evaluating what you see under supplier constraints

How to triangulate evidence when direct access is limited, and recognise audit-relevant red flags such as restricted sampling or inconsistent records

06Managing challenging situations professionally

How to handle defensiveness, commercial pushback, and boundary disputes, and decide when to pause, rescope, or escalate based on clear decision points and internal alignment

07Audit documentation and handover

How to maintain workpapers that link evidence to criteria and support later reporting, and define handover packages that meet downstream reporting and follow-up needs

08Case-based workshop

Applying the learned concepts, methods, and approaches in a realistic case setting

Outcomes

Learning outcomes

01

Define a supplier audit scope and brief using contractual and mandatory requirements as criteria

02

Translate audit criteria into supplier-specific evidence targets and an evidence request plan

03

Document audit workpapers that clearly link evidence to criteria and support downstream decisions

Choose and structure an on-site, remote, or hybrid supplier audit approach appropriate to access constraints

Run supplier audit activities in a controlled manner, managing timing, access, and interface tracing

Evaluate supplier evidence under real-world limitations using triangulation and consistency checks

Materials

The content and the assessment

Written module

The full content in writing, complete in itself. Videos are recorded for parts of it as an alternative way through, and the written module always carries everything.

Exercises

Graded work on the case organisation's own registers: structured answers checked against the encoded case, written answers scored against a rubric traced to it, with a trainer holding the final word on every assessed item.

On completion

The assessed exercises must be passed before the certificate is issued.

Scheduling

No public run of Supplier Auditing is scheduled at the moment. Tell us you are interested and we will let you know when the next one opens, or discuss running it in-house.

Case organisation

You work inside a company that already has the problem

Exercises run on one case organisation, carried across modules rather than restarted, so what you build here is what the next module finds.

Northstar Integrated Services AG is a group headquartered in Zurich, providing digital operations platforms and managed services to regulated organisations across Europe. It has not always been that. It began in 2008 as a field-operations firm of about twenty-five people, and what first forced documented decisions and named accountability on it was not growth but a single regulated customer. It now runs an acquired business in Poland and the Czech Republic through a subsidiary that kept its own legal identity, which is where the interesting failures live: group instruments rolled out operationally and never put in force by the governing bodies of the subsidiary itself.

Linked registers
Organisation and people, risks, objectives, policies and documents, findings and reviews, third parties, processes

Not a case study
Nothing is summarised for you; the evidence is where it would really be

It has a history
The organisation has a timeline, and modules enter it at different points, so a structure can be studied before it broke as well as after

It crosses borders
A Swiss parent, an acquired operating business in Poland and the Czech Republic under its own legal entity, and customers in several jurisdictions

Why it matters

Judgement is not trained on tidy examples, and it is not trained on a fresh one each week. Northstar is deliberately untidy, and modules enter it at different points of its history, so you see a governance structure being built, outgrown and rebuilt rather than a finished one. What you decide in one module is what the next one finds.
