Product quality is one of the key foundations for the success of any commercial or industrial organization. Its impact goes beyond customer satisfaction—it extends to the company’s reputation, customer loyalty, and long-term sustainability in the market. Product quality can be defined as the extent to which a product meets customer expectations and needs while complying with specific standards and specifications. One of the main indicators of a high-quality product is reliability. A reliable product performs consistently well over time without frequent issues or malfunctions. The durability of the materials and precision of the manufacturing process play a significant role in ensuring this reliability. مرره حلوووووو
