大家好：
为进一步规范ERP发版工作，加强研发质量管控，在2017年初，我们对ERP产品发版管理制度V1.1进行了优化，详细调整点如下：
1、结合公司《ERP产品全生命周期管控策略V4.0》，将孵化期产品和成长&成熟期产品的发版活动进行区分细化
2、新增定义《ERP研发质量标准v1.0》
3、结合公司《产品PMO管理机制v1.0》，修订《产品上市评估表》形成2017年版本
4、针对主项目和子项目协作问题，梳理形成《ERP发版-主项目工作清单v1.0》
经ERP353和云ERP1.0SP3发版前工作的试运行、各事业部核心角色的评审，最终经产品PMO的审核，现正式发布ERP产品发版管理制度V2.0，即日生效！
如对本管理制度有任何疑问，欢迎咨询各团队QA";
