阿里计划未来100天每周六推“超级星期六”,原来马云要求淘宝闪购稳定在8000万单

7月14日,淘宝闪购联合饿了么宣布,在订单结构向全品类深度拓展的同时,日订单量再次突破8000万创新高(不含自提及0元购)。 淘宝闪购日活跃用户数在突破2亿基础上,上周(7月7日至13日)又环比净增15%。但真正值得注意的是,淘宝闪购在8000万的订单规模下,准时率稳定在 96%。稳固准时率、巩固基本盘似乎是目前阿里外卖业务的重点。 某位阿里员工就曾表示,"就怕冲得太快后,其他能力都没跟上,反而适得其反,原本好的基本盘都没了。" 马云要求淘宝闪购稳定在8000万单,巩固基础,再往上冲 据新浪财经消息,阿里创始人马云在上周六、日要求淘宝闪购"稳定在8000万单",先提升好能力,巩固好基础,再往上冲。马云此举或为叫停此前淘宝闪 购"Tic-Toc 节奏"计划。 而淘宝闪购"Tic-Toc 节奏"计划:即一个周六冲刺新高,下周六保持上周水平,直至 8 月 7 日立秋当天冲击 1 亿单,或会因盲目追求增速,而致使系统稳定 性、物流配送、售后服务等其他能力滞后,影响整体基本盘。 这就不难理解,淘宝闪购为何要持续投入100天每周六都推"超级星期六"了。7月13日,阿里又宣布计划未来100天,每周六推"超级星期六",发放总 ...
