-## 首问负责，严禁推诿
+### 1、首问负责，严禁推诿
+首问负责制：无论是线上问题还是测试问题，第一责任人要负责对问题的跟踪，解决以及闭环。
+
+
+### 2、每天分析线上异常日志，提交结果
+如： 商品服务调用失败，查询品牌超时，定位超时原因是网络原因，或者程序问题，或者脚本写的有问题。并给出相应的修改建议。

+### 3、每周一之前检查组内下周工作计划，最大粒度的工作不超过3人天
+每周一要输出本周的开发计划，并录入到伙伴云表格中，并定时更新状态。参考
+https://app.huoban.com/apps/1745147
+
+### 4、每月至少组织一次review代码，提交review结果
+组长组织组员每月review重要代码，并提交review结果，以及修改建议
