Inspections and quality control measures exist in all industries. However, they have subtle differences. Inspections emphasize quality and separating good products from bad ones until enough products are manufactured. In contrast, quality control improves the production process such that only good products are manufactured. Indeed, inspection serves as a tool for quality control. As the situation improves, the need for inspection diminishes.
Product and process quality can be considered from different angles. Product or service quality involves giving customers what they want. High-quality products or services which no one is willing to use merely waste resources without creating value. A modern view of quality defines it as the incurred loss starting with the launch of a product. This may seem unintuitive at first. However, we must realize that products can only create value by meeting customer requirements.
