Purpose: To control the changes that occur in the company's operations and ensure that changes are in an effective and controlled state.\n\n2. Scope:\n2.1 Changes proposed by customers, such as design changes, requirement changes, and delivery changes.\n2.2 Process changes that occur internally within the organization, including all changes related to people, machinery, materials, methods, environment, and measurement.\n2.3 Changes proposed by suppliers.\n\n3. Responsibilities:\n3.1 The Sales Department is responsible for receiving customer change information and documentation, organizing the review of customer change content, internal communication of customer requirements, liaising with customers regarding internal change matters, and approving internal change applications and resubmitting PPAP after changes.\n3.2 Relevant functional departments are responsible for reviewing customer change information, timely application for internal process changes, controlling the change process, and resubmitting PPAP after changes.\n3.3 The Quality Department is responsible for assessing the feasibility of internal change applications and monitoring the implementation of internal and external changes.\n3.4 Other departments are responsible for transmitting and supervising the execution of supplier change information.\n\n4. Management Contents:\n4.1 Classification of changes:\n4.1.1 Changes can be distinguished by their source:\na. Customer changes\nb. Internal process changes\nc. Supplier process changes\n4.1.2 Changes can be distinguished by their type:\na. Design changes or engineering modifications\nb. Process changes\nc. Capacity changes\nd. Delivery changes\n4.1.3 Changes can be distinguished by their stage:\na. Changes that occur during new product planning or development stages\nb. Changes that occur during mass production stages\n\n4.2 Control process for customer design changes:\nWhen the Sales Department receives customer change information, the following control process should be followed.\n\n4.2.1 Changes during mass production stage:\n4.2.1.1 After receiving customer change notification, the Sales, Administration, Technology, Production, and Quality departments should be promptly notified in the form of an "Engineering Change Request" document. The request should include detailed information such as the reason for the change, the content of the change, whether a resubmission of PPAP is required, the content and timing of the submission, and the disposal method for the products before the change (if there are significant changes, relevant personnel should consider holding a meeting and include the details in the notification document). After the review by the relevant departments and approval by the responsible supervisor, the document should be distributed to the relevant departments.\n4.2.1.2 Review of relevant drawings or documentation:\nAfter receiving the change information and drawings, the relevant departments should promptly review the content of the change (if necessary, business personnel should convene a meeting with relevant department personnel for review), ensuring that each department fully understands the change content in order to develop practical and feasible control plans that ultimately meet customer requirements. If it is found during the review that it is difficult to meet the customer's change requirements, it should be promptly raised and resolved through negotiations between the business department and the customer.\n4.2.1.3 Statistics and handling of design change products:\nAfter receiving the change notification and inventory statistics requirements from the sales personnel, the manufacturing department must promptly count the products in process before the design change, summarize the information to the supervising department, and have the warehouse department consolidate the (semi-)finished product inventory. The results should be communicated to the supervising department for changes. At the same time, the sales department should summarize the quantity of in-transit products, third-party warehouse finished products, and customer-owned finished products before the change, and negotiate the disposal method with the customer. Ultimately, the business personnel should inform the relevant departments of the product handling plan.\n4.2.1.4 The Technology Department should promptly adjust the process plan and modify the fixtures according to the design change requirements. They should provide an estimation of the process and fixture modification cycle and cost to the sales department, and modify relevant self-made drawings and process documents. These should be distributed to the relevant departments, while also providing technical services for trial production or mass production of design change products.\n4.2.1.5 Inspection, confirmation, and validation of trial production or mass-produced products after design changes should be organized by the supervising department responsible for the changes.\n4.2.1.6 Production and quality department personnel should strictly segregate and label the products produced before and after the design change. They should also arrange trial production or reorganize production according to inventory and customer order requirements in a timely manner. If trial production is necessary, the supervising department is responsible for arranging it.
