团队管理预算的重要性
｜
67
根据实时数据评估差异值，以查看哪些团队的数据偏离了季度预测值，然后与他们一道
寻找解决方案。每日一次的评估能迅速识别差异，并在差异变大之前将其扼杀在摇篮里。
之后，在支出超过预测的当天，管理层就能了解该情况。管理层和业务部门将据此开会
讨论增加成本（如果存在的话）所产生的价值是否合理。
持续评估有助于业务部门进行更优决策，保持持续进步，同时也展现了支出降至低点所
需的最短时间。设置预算不等于不允许支出，而是提供一种参照，用于识别支出何时偏
离计划。从某种意义上来说，这也促进了各部门之间的对话。
机器学习才是精准预测支出的出路，但仅应用单一的模型或算法是不够的。一些机器学
习算法可以完美地处理冗长的历史成本数据，另一些机器学习算法则擅长处理有限的数
据点。你的账户里可能有很长的历史成本数据，但当你引入新的工作负载或开了新账户
时，可能之前的机器学习算法便无法有效工作了。因此，结合多种场景的算法集成方法
是适应历史变化的更有效方法。
在进行成本预测时，你必须考虑一些重要因素 ：你要预测哪个时间段的支出？（此时的
支出模式可能异于六个月前）你采用的成本指标是哪个？它会被分期付款至预付费实例
的购买中吗？它随约定价格而定吗？团队协调更是重中之重，所以你必须确保尽快协调
成本指标，使各部门保持一致。
团队管理预算的重要性
我们很容易将“预算”错误地理解为一种严格的限制管控措施。但预算不需要也不该阻挡
创新的进程。正如之前所说（此处值得重复），
