PPM (Parts Per Million) levels are a crucial metric in the automotive industry and their reduction is a constant goal for SQA (Supplier Quality Assurance) and SQE (Supplier Quality Engineering) professionals.

PPMs represent the number of defective parts per million parts produced. This indicator provides an accurate measure of quality in terms of defects. Let's explore strategies and best practices to help vendors decrease PPMs, which will result in greater efficiency and competitiveness in the industry.

The Importance of Reducing PPMs

Before delving into strategies, it's important to understand why reducing PPMs is critical during vehicle and component production. A high level of PPMs can have a significant impact, starting with a vendor's reputation, their relationship with customers, and ultimately, their success in the marketplace. High PPMs can lead to warranty claims, rework costs, and loss of customer confidence. Therefore, reducing PPMs is not only a goal, it is also a pressing need for automotive manufacturers and suppliers.

Practical Strategies to Decrease PPMs

1. Quality Management

This involves the implementation of an effective quality management system that ensures that production processes meet the required specifications and standards. ISO/TS 16949 certification is an example of a widely recognized quality standard in the automotive industry.

2. Process control

Process control is the most important point for detecting and preventing defects in the early stages of production. Implementing tools such as Statistical Process Control (SPC) and inline inspection can help monitor and keep processes under control, thus reducing the likelihood of defects.

3. Continuous follow-up

Incorporate real-time tracking systems to monitor quality. It promotes the identification and constant correction of problems. Lean Six Sigma methodology and Failure Mode and Effect Analysis (FMEA) are widely used in this industry to detect, correct and improve quality and reduce PPMs. By eliminating defects and reducing variability, a constant improvement in quality is achieved.

4. Collaboration with suppliers

Sharing information about quality standards, expectations, and best practices can help align the efforts of everyone involved in the supply chain to reduce PPMs.
