Supplier Auditing
Munich – “Bosch’s Supply Problems Cause BMW Sales Drop,” read the headline in the Handelsblatt. Headlines like this—or similar ones about production stoppages resulting from supplier bottlenecks—are appearing with increasing frequency in the business press. In BMW’s case, Bosch was unable to continue supplying steering gears due to its own problems with a casting supplier.
Single Sourcing: Both a Strategy and a Risk
Automakers and their suppliers share a challenging business relationship. Characterized by complex supply chains (increasing supply chain depth and geographic span of supplier relationships) and growing interdependencies, the importance of suppliers and their delivery performance is steadily increasing. Due to rising cost pressures, OEMs are consciously placing themselves in a position of dependence on a single supplier, for example, through single sourcing. The goal of this procurement strategy is to reduce costs through synergies such as the consolidation of purchasing volumes and joint research and development. However, the disadvantage of a single source of supply becomes apparent due to the high level of dependence on the supplier. Furthermore, suppliers are closely synchronized with the OEM’s production process. Virtually zero-inventory supply chains, as well as the shift to production-synchronized delivery (JIT—Just in Time and JIS—Just in Sequence), reduce inventory costs on the one hand but, on the other hand, increase the demands on delivery performance. If a link in the supply chain fails, supply bottlenecks will disrupt the OEM’s production more severely than before, thereby increasing the extent of damage caused by the supply disruption.
Supplier Audits as a Preventive Measure
These conditions necessitate on-site preventive measures, as the OEM can only reduce the likelihood of a supply bottleneck through such measures. One such preventive measure is the supplier audit. Supplier audits serve to identify potential risks at an early stage and present them transparently. The sooner the OEM detects potential risks at the supplier, the greater the likelihood of proactively preventing potential supply bottlenecks. Unlike reactive supply assurance, the sustainable empowerment of critical suppliers has a positive long-term impact on delivery performance and, consequently, on costs.
Objectives of the Supplier Audit
On-site supplier visits are very time-consuming, but they offer the greatest benefits in terms of risk reduction and the early resolution of supply issues. In addition to delivery quality, it is crucial to focus on preventing potential field risks as part of the supplier audit. Furthermore, efforts should always be made to improve both direct and indirect production areas, such as optimizing floor space and employee utilization, as well as synchronizing production differences between suppliers and OEMs (production based on the pull principle).
Selection of Suppliers to Be Audited
Identifying critical suppliers is key to the feasibility of supplier audits. A supplier’s field quality performance and current delivery performance—such as on-time delivery and delivery quality—are only part of the identification criteria. Rather, a comprehensive understanding of the supply chain, including all n-tier suppliers, is sufficient to determine the critical supplier locations in terms of production technology and structural dependencies.
