The purpose of preparing a control plan (QC engineering drawing) is to help produce high-quality products that meet customer requirements. It is through the overall design, selection and implementation of value-added control methods to provide a structural approach to achieve the above purpose. The control plan (QC engineering drawing) is maintained and used throughout the product life cycle. In the early stages of the product life cycle, its main purpose is to provide information and communicate the initial plan for process control; after that, it leads manufacturing to how to control the process and ensure product quality

编订控制计划（QC工程图）的目的是帮助生产满足客户要求的优质产品。它是通过总体设计、选择和实施增值性控制方法以提供结构性的途径来达到上述目的.控制计划（QC工程图）保持和使用于整个产品寿命周期。在产品寿命周期早期，其主要目的是提供资料和传达流程控制的初始计划；其后，它把制造引向怎样控制流程和确保产品质量
