Do You Like Dashboards?
Not much happening lately, what with the holiday in the US and the obsession with bargain hunting on Black Friday and Cyber Monday.
A while back, Paul (@ppedrazzi) and I were sharing our mutual unhappiness with application dashboards. They always seem like a good idea for quick and easy information consumption, but inevitably, dashboards are messy to develop and ultimately ignored by users.
I had a revelation over the long weekend, while reading How We Decide; there’s too much information for the brain to capture.
I know, obvious.
Jonah Lehrer discusses the classic assertion that the brain can handle only seven data points at once, which I believe influenced the American phone number sequence, among other things.
And even seven is a stretch, as thinking power seems to decrease dramatically as more data are introduced.
But it isn’t as obvious when you’re designing a dashboard.
Typically, the requirements for a dashboard are numerous, and since your target user is likely a decision-maker or executive, you want to account for as many as possible.
This is where the problems start because a dashboard needs to present the most relevant information, but accommodating more functionality means decreasing how much the brain can focus on, important or otherwise, rendering the entire dashboard useless.
Couple this with the fact that many users don’t really know what is really important beyond a handful of functions.
Therefore, a dashboard with a bunch of information quickly gets overwhelming.
Think about the cars, the original dashboard. Aside from speed and a fuel gauge, what else about the car is critical. Probably engine temperature, an area for warnings, maybe RPMs. What about time and direction?
That’s already seven pieces of information.
But modern cars go well past seven. If you watch Top Gear, you’ll see how overly complicated cars frustrate their users, and it seems the amount of dashboard information is directly proportional to the cost of the car.
All the really hard work goes into boiling down the many, varied requirements for a dashboard into the no more than seven really important ones.
And that’s really tough.
So, what’s the answer, or do you love dashboards the way they are?
