产品验证时工艺验证的一部分,即PPQ,product performance qualification, 它是工艺验证的第二阶段
工艺验证包括以下三个方面
Stage 1-Process Design: The commercial manufacturing process is defined during this stage based on knowledge gained through development and scale-up activities.
第1阶段-工艺设计:在该阶段,基于从开发和放大试验活动中得到的知识确定商业化生产过程。
Stage 2-Process Validation (process performance qualification,PPQ): During this stage, the process design is evaluated to determine if the process is capable of reproducible commercial manufacturing.
第2阶段-工艺验证:在这一阶段,对已经审计的工艺进行评价来判断其是否能够进行重复性的商业化生产。
Stage 3-Ongoing process monitoring: Ongoing assurance is gained during routine production that the process remains in a state of control.
第3阶段-持续工艺监控:在日常生产中一直保证工艺处于受控状态。
