Control Plan Management Specification: Minimizing Variation in Processes and Products

Control Plan Management Specification\n\n1. Purpose\nThis document provides a concise written description of the system for minimizing process and product variation. It is a dynamic file that reflects the current control methods and measurement systems being used.\n\n2. Scope\nThis specification applies to the management of control plan development, review, approval, changes, and execution.\n\n3. Authority and Responsibility\nThe development, implementation, and modification of control plans are primarily carried out by the project team, led by the Technical Department.\n\n4. Definitions\n4.1 Sample Control Plan: A description of dimension measurements, material, and performance tests to be conducted during sample production. Sample control plans are prepared only when requested by customers.\n4.2 Trial Production Control Plan: A description of dimension measurements, material, and performance tests to be conducted after sample production and before full-scale production.\n4.3 Production Control Plan: A document describing product/process characteristics, process control, tests, and measurement systems during batch production.\n\n5. Task Content\n5.1 Control Plan Format:\n5.1.1 Control plans should be written in a standard format.\n5.1.2 If the customer specifies a format, that format should be used.\n\n5.2 Control Plan Development:\n5.2.1 Control plans must be developed by the project team, with members from the Technical Department. After completion, the control plan should be reviewed by the project team using the "Control Plan Review Checklist" and signed by all project team members upon approval.\n5.2.2 The control plan consists of 26 fields that need to be filled in. The requirements for each field can be found in the customer reference manual: Advanced Product Quality Planning (APQP).\n5.2.3 Control plans cannot replace the information contained in detailed operator instructions.\n5.2.4 A single control plan can be applicable to a group or family of products produced from the same process and raw materials.\n5.2.5 The core team should identify the special characteristics that make up the product and process from all sources, and all special characteristics should be listed in the control plan.\n\n5.3 Control Plan Distribution:\n5.3.1 Control plans are technical documents and should follow the document control procedure for distribution.\n5.3.2 Control plans should be distributed by the Technical Department to the Production and Quality Departments.\n\n5.4 Control Plan Execution:\n5.4.1 The production department should strictly follow the control methods and measurement systems specified in the control plan. The quality department should conduct inspections and tests in accordance with the control plan.\n\n5.5 Control Plan Modification:\n5.5.1 Control plans are living documents. When any changes occur that affect the product, manufacturing process, measurement, logistics, or supply sources, the Technical Department should organize a re-evaluation and update of the control plan by the original project team members.\n5.5.2 After modification, the control plan should be reissued by the Technical Department, following the document control procedure.\n5.5.3 If no changes occur, the control plan should be reviewed every six months.\n\n6.
