Audit plan in a nutshell:
An audit plan is a structured document that sets out in detail the timing, responsibilities and scope of a planned audit. For purchasing, it serves as an essential tool for the systematic evaluation of suppliers and internal processes in order to ensure quality standards and identify potential for improvement.
Example: An automotive supplier draws up a three-month audit plan for Q1 2024, which includes 12 supplier audits, with two days scheduled per audit with three auditors each and specific focal points such as quality management, process safety and sustainability standards defined.

What is an audit plan?
An audit plan is a structured document that defines the process, scope and objectives of an audit. In procurement, the audit plan is used to systematically review purchasing processes, supplier relationships and compliance requirements. It ensures that all relevant areas are taken into account and that the audit is carried out in an efficient and targeted manner.
Core elements of an audit plan
Importance of the audit plan in purchasing
In procurement, the audit plan is a key tool for ensuring quality and compliance within the supply chain. With a carefully created audit plan, buyers can minimize risks, optimize processes and evaluate the performance of suppliers. This contributes significantly to the transparency and efficiency of purchasing processes and supports the strategic orientation of the company.
Creation of an effective audit plan
The creation of an audit plan includes setting the audit objectives, defining the scope of the audit, selecting the audit methods and developing a detailed schedule. This guarantees a structured approach and ensures that all relevant aspects of the procurement process are reviewed.
Practical example
Example: Auditing a new supplier
1. define audit objectives: Review the new supplier's production capacity and quality standards to ensure that it meets the requirements.
2. define the scope of the audit: Focus on the supplier's production processes, quality management systems and logistics capacities.
3. select audit methods: Conduct site visits, interview key personnel and analyze quality documentation.
4. create a schedule: Setting the audit date, planning the journey, assigning responsibilities within the audit team and communicating the plan to the supplier.
