Observations and situational analysis:
Tier 1 suppliers, as direct providers of materials or components to OEM (Original Equipment Manufacturers), play a critical role in the supply chain, and their schedule performance and quality issues can significantly impact customers. Below is an overview of common issues and their effects, based on our insights and experience.
Schedule Performance Issues
Delays in Delivery:
Inefficient and/or incapable manufacturing processes, raw material shortages, logistical challenges, or poor coordination with Tier 2 suppliers can have a negative impact on deliveries. For example, a shortage of raw-materials and a shortage of production talent can exacerbate delays. And, some suppliers regretfully utilize manufacturing processes which lack the appropriate level of statistical capability.
Impact on Customers:
Late deliveries disrupt production schedules, especially in just-in-time (JIT) manufacturing, leading to halted assembly lines, increased costs, and delayed product launches. Customers may face penalties for failing to meet their own delivery commitments or lose market share due to unfulfilled orders.
Inaccurate Lead Times:
Due to many of the same reasons as listed above, suppliers may overestimate their capacity or fail to account for dependencies on sub-tier suppliers, leading to unrealistic lead time promises.
Impact on Customers:
Manufacturers relying on precise timelines may face inventory shortages or overstocking, increasing inventory costs and inefficiencies. This can also erode trust in the supplier relationship.
Quality Issues
Defective Materials or Components:
Inadequate quality control, inconsistent testing, or lack of visibility into sub-tier supplier processes (e.g., 65% of companies have limited visibility beyond Tier 1). Small and medium-sized enterprises (SMEs), common in sub-tier supply chains, often lack robust quality management systems. Statistical process control of quality is often less than robust in smaller suppliers.
Impact on Customers:
In addition to missed shipments and poor schedule performance, defective parts lead to product recalls, safety issues, or rework, increasing costs (up to 30% more in quality defect-related costs) and damaging brand reputation. For example, a faulty component in the automotive industry can lead to customer dissatisfaction if it affects the final product’s performance.
Non-Compliance with Standards:
Suppliers may fail to meet regulatory or industry standards due to insufficient training, outdated processes, or lack of certifications. Aggregating these multi-industry practices into a common set of principles, High Value Manufacturing (HVM) has established our 11+1 Quality Management Strategies.
These strategies are based on the generic principles of ISO 9001 and AS9100. The specific strategies meet the expectations as delineated by IAQG (International Aerospace Quality Group), VDA (Verband der Automobilindustrie), and AIAG (Automotive Industry Advisory Group) certification organizations. Aerospace, Defense, Automotive, and many other industries have applied these Quality Management Strategies. ISO/IATF 16949 certification has also been achieved by utilizing these basic strategies.
These strategies start with “Capable and Stable Manufacturing Processes” maintained and controlled via Statistical Process Control. That is the “+1 Quality Management Strategy” and without that, the other 11 strategies will not achieve maximum potential.
HVM’s process for addressing client challenges begins with a confidential conversation. During a complimentary Zoom consultation, HVM conducts a Manufacturing Health survey that identifies potential operational issues and options for next steps. The team at HVM works closely with plant leadership to assess, recommend, and implement improvements directly on the plant floor.
Impact on Customers:
Inconsistent quality leads to unpredictable product performance, customer complaints, and increased inspection costs. This is particularly critical in industries like automotive or medical devices, where quality directly affects safety and reliability.
Broader Impacts on Customers
Operational Risks:
Delays and quality issues disrupt production, leading to inefficiencies and higher operational costs.
Financial Losses:
Rework, recalls, and lost sales due to quality defects or delayed deliveries can erode margins. For instance, poor supplier management can lead to significant margin erosion.
Reputational Damage:
Customers face dissatisfied end-users, damaged brand trust, and potential loss of market share when products fail or are delayed.
By addressing these schedule and quality challenges proactively, Tier 1 suppliers can strengthen their relationships with customers, minimize disruptions, and enhance overall supply chain resilience.
