Abstract: At present, in the stage of automobile product development, a large number of process changes are involved, and the current change process regardless of the size of the change, the unified way of first evaluation, then approval, and then implementation, the process is relatively simple, and the approval is cumbersome, which is not only inefficient, but also causes a large amount of waste of resources, and seriously affects the work efficiency and product quality. Therefore, this paper refines and summarizes the process change process of the existing car companies into five stages: change requirement, change application, change review, change verification, and change implementation, and proposes a process change control optimization strategy suitable for the automobile development stage, which can improve work efficiency and ensure product quality at the same time, and provide a theoretical basis for process change in the vehicle development stage.

Key words: process changes; optimization strategy; management methods; vehicle development stage

摘要： 汽车产品在开发阶段涉及大量的工艺变更，目前的变更流程不管变更大小，统一需要 先评估后批准，再执行的方式，流程较为单一、审批繁琐，不仅效率低下，也造成了大量的 资源浪费，严重影响工作效率及产品质量。因此，文章将现有各车企过程变更流程进行提炼、 归纳为变更需求、变更申请、变更评审、变更验证、变更实施五个阶段，并提出一种适用于 汽车开发阶段的过程变更管控优化策略，在提高工作效率的同时也能保障产品质量，为整车 开发阶段过程变更提供理论依据。
