Companies have been cited by FDA for not validating spreadsheets used for in-process analytical calculations, finished product analytical calculations, tracking and trendy quality metrics, and for their databases or lists.
如果你的电子表格适用于任何受相关法规监管的活动,则必须被验证。FDA引用了多家公司未对其用于工艺过程分析计算、成品分析计算、跟踪和分析质量量度趋势及其数据库或列表的电子表格进行验证。
