At its core, an SQE's role is about building trust—trust in suppliers, trust in processes, and, ultimately, trust in the products delivered to customers. This trust doesn’t come easily. It’s earned through meticulous attention to detail, clear communication, and a relentless focus on continuous improvement. In this book, we’ll explore the challenges and triumphs of supplier quality engineering. We’ll dive into the technical skills required to succeed, from statistical analysis to auditing. We’ll examine the interpersonal dynamics of working with suppliers, buyers, and production teams. And we’ll celebrate the moments when everything comes together, and a product is delivered to a satisfied customer.
