7.0 PROCESS 流程

7.1 Issue ECR工程变更申请的提出

7.1.1 Customer Required ECR 客户要求的工程变更

AQP issue ECR for customer change(Product/Capacity,etc) and lead to evaluate ECR.

项目部接到客户变更需求(产品/产能等时，提出ECR，组织相关部门评估。

Internal ECR 内部需求的ECR

A) Each department could issue ECR when necessary. Purchase department release ECR for supplier change. AQP department release ECR for engineering change. Production department release ECR for production change. Quality department release ECR for quality issues.

相关部门有需求时，可以提出工程变更申请。供应商相关的工程变更由采购部提出；工程相关的工程变更由项目部提出；生产相关的工程变更由生产部提出；质量相关的工程变更由质量部提出。

B) Program Manager lead to evaluate ECR.

公司内部的ECR由项目经理组织相关部门评估。
