2.0 DEFINITION AND PURPOSE:定义和目的

GP-12 Early Production Containment requires a Pre-Launch Control Plan that is a significant enhancement to the supplier's production control plan and raises the confidence level to ensure that all products shipped will meet GM’s requirements. The pre-launch control plan will also serve to validate the production control plan. The Pre-Launch Control Plan should take into consideration all known critical conditions of the part as well as potential areas of concern identified during PPAP.

GP12 早期生产围堵政策需要一项试运行控制计划，这份计划极大地增进了供应商的生产控制计划以及提升自信心，保证所有发出的产品都符合GM要求。试运行控制计划也可用来确认生产控制计划。试运行计划应考虑到部件的所有已知临界条件和PPAP期间所关注的范围。

The purpose of GP-12 is to: 其目的：

?Validate the supplier’s production control plan 确认供应商生产控制计划

?Protect our assembly and manufacturing centers and service part warehouses from quality non-conformances during critical periods

确保在关键时期里的装配制造中心和配件仓库的产品质量不受损。

?Document the supplier's efforts to verify control of its processes during start-up, acceleration, after revisions to the manufacturing process, or when manufacturing runs are separated by 3 months or more

为供应商提供文件证明，是对其在核实从开始生产、加速生产、到生产步骤修订之后或是中断了3个月或者更久的制造运行间的过程控制所做的努力。

?Ensure that any quality issues that may arise are quickly identified, contained, and corrected at the supplier's location

保证出现的任何质量问题都要由供应方那边快速地指出确定并及时作出补救修正。

?Increase involvement and visibility of supplier’s top management 加大供应商高管理层的参与力度。
