Actual yields should be compared with expected yields at designated steps in the production process.
Expected yields with appropriate ranges should be established during process validation or from historical data.
翻译要点:
实际产量应与预期产量进行比较;
预期产量应在工艺验证或历史数据基础上设定合理范围;
明确产量要在合理范围内波动,超出范围要调查。
11.6 Deviations(偏差)
Any deviation from established procedures should be documented and explained.
Critical deviations should be investigated and the investigation and its conclusions should be documented.
