看板不是报表：中小企业数据可视化的四个设计原则A Dashboard Is Not a Report: Four Design Principles for SME Data Visualization
我们复盘了交付过的二十余个经营看板，发现真正被每天打开的只有三个。差别不在技术，在设计。We reviewed more than twenty business dashboards we have delivered and found that clients actually open only about three of them every day. The difference isn't technology—it's design.
「做个数据看板」是我们接到过最多的需求之一。但交付之后，客户每天真的会打开的看板，平均只有三个。“Build us a data dashboard” is one of the most frequent requests we receive. But after delivery, clients actually open only about three dashboards a day on average.
问题往往不在技术，而在没人定义过「看了之后要做什么决定」。The problem usually isn't technical. It's that no one has defined what decision you are supposed to make after looking at it.
原则一：每个数字都要绑定一个动作Principle 1: Every Number Should Be Tied to an Action
如果一个指标出现异常，看板上没有任何对应的处理指引，那它就没有存在的必要。好的看板会直接写清楚：超过什么阈值需要做什么。If a metric goes off track and the dashboard offers no guidance on how to respond, it has no reason to exist. A good dashboard states plainly what to do when a threshold is crossed.
原则二：先做口径，再做图表Principle 2: Define the Metrics Before Building the Charts
我们在项目早期一定要求客户把指标口径写下来：销售额含税还是不含税、退款怎么算、跨月订单归哪个月。口径不清时，画得再漂亮的图也只是把分歧可视化。Early in every project, we require the client to write down metric definitions: is sales revenue before or after tax, how are refunds counted, which month do orders that span months belong to? Without clear definitions, even the most polished charts only visualize disagreement.
原则三：分层而不是平铺Principle 3: Layer, Don't Flatten
老板看的是三行数字，一线看的是今天的待办。把所有指标平铺在一屏上，等于什么都没说。Executives need three lines of numbers; frontline staff need today's to-do list. Flattening every metric onto a single screen says nothing to anyone.
原则四：移动端优先Principle 4: Design for Mobile First
我们统计客户的实际打开场景，超过七成是在手机上看。看板的第一屏必须在竖屏手机上读完——这会倒逼你砍掉一半的指标，而那一半通常本来就不重要。When we measured where clients actually open their dashboards, over 70% of views were on phones. The first screen must be readable on a phone in portrait mode—which forces you to cut half your metrics, and that half usually wasn't important anyway.
