A good dashboard feels like a window. You look through it and see how the business is doing. In practice, it is closer to a painting. Someone chose what to put in the frame, what colors to use and where to start the axis, and each choice shapes what you believe.
None of that is dishonest by default. But it means you need a few habits for reading a dashboard, or it will lead you around. Here are the three we use every week.
Habit one: ask what it is compared with
Every number is meaningless without something next to it. Four hundred leads this month is neither good nor bad until you know what it is compared with.
Compared with last month? That might be a holiday month. Compared with the same month last year? Better, if the business has not changed. Compared with the target? Best, because the target says what you wanted.
When someone shows us a chart, our first question is always against what? A line going up feels like good news. Put it next to the target line and it may be going up more slowly than it needs to.
Watch the axis too. A chart that starts at 90 instead of zero can make a 3 percent change look like a cliff. It is a useful trick for showing small differences, and an effective way to fool yourself when you forget it is there.
Habit two: check the span of time
A week of data is a small sample, and small samples are noisy. One viral post, a rainy Tuesday or a competitor sale can swing a week in ways that mean nothing for the quarter.
We try to look at the same number across three spans: the last week, the last four weeks and the quarter to date. If all three tell the same story, believe it. If they disagree, the shortest span is usually the noise.
Beware of the starting date as well. A chart that begins right after a bad month will always look like growth. Ask what happened just before the first point on the left.
Seasonal businesses need extra care. Comparing December with November tells you almost nothing about a gift shop. Compare December with last December, then ask whether anything else has changed.
A chart is an argument. Ask who is making it.
Habit three: find the number that should move too
This one catches more mistakes than the other two together. Before you act on a chart, find a second number that should move if the first one is real, and check that it did.
If ad clicks are up 30 percent, sessions on the site should be up too. If they are not, the clicks may be bots, or a tracking tag broke. If bookings are up, revenue should follow within a few days. If it does not, maybe the new bookings are all discounted.
This is the best protection we know against a broken measurement. Tracking goes wrong far more often than people expect: a tag deleted during a redesign, a form that stopped sending, a currency set wrong. The error shows up as a lovely, confident chart.
Pair your numbers. Whenever a metric changes, name its partner and look at it.
Look for what is missing
Dashboards show what was measured. They say nothing about what was not. If customers also phone you, visit in person or buy through a partner, the dashboard does not see them, and it quietly suggests they do not exist.
Ask what the chart cannot see. If the answer is a lot, treat the dashboard as one view, not the truth.
Be careful with averages
An average can hide the most interesting thing in your data. If your average order is $80, that might be a hundred orders of $80, or ninety of $20 and ten of $620. They call for very different decisions.
When you can, look at the spread as well as the average, even if it is just the smallest, the largest and the middle. It takes a minute and often changes the conversation.
Write down what you expected
Here is a habit that sounds childish and works. Before opening the dashboard, write down what you expect to see. A number or a direction, no more.
Then compare. When you are wrong, you learn something. When you are right too often, you may be looking at the same stories and missing changes. It also stops you from explaining away any result afterward, because you committed first.
When in doubt, ask for the sum
If a number looks too good, ask for its sum. Where does it come from, what was added, what was left out? If nobody can show you, wait before acting on it.
That is the rule behind our own reports. Every figure comes with the numbers it was built from, and a second person has checked them. It is not glamorous, but it is how you keep a pretty chart from running the business.
Pass it on
In short.
If you only have a minute, these are the three things to keep.
