Product projects strictly implement technical status management in accordance with the Q/GR G0477-2019 “Technical Status Management Procedures” standard. Technical status management encompasses technical status identification, technical status control, technical status documentation, and technical status review. Technical status management should commence at the conceptual design stage and continue throughout the entire lifecycle of the product, including design, development, procurement, production, testing, installation, service, use, and disposal. It should clearly and accurately reflect the technical status of the product and effectively control any changes to the technical status.
