Dashboards are useless! They are a waste or time. Get Netflix if you want to watch something. It's cheaper than any other option.
I repeated those words on many public occasions. I think that companies exaggerate the need for dashboards. They spend a lot of effort creating a bunch of graphs and put a lot of people in charge of staring at them. As if that's going to help anyone. The main advantage of dashboards is that they are colorful and full of lines, boxes, and labels. Those properties are always an easy sell to decision makers like CTOs and heads of departments. When a software vendor comes to a meeting with decision makers with authority to write checks, he knows that there is no sale without "pretty colors". It does not matter what that software does, but how it looks like. That's why every software company focuses on dashboards.
Think about it. What good is a dashboard for? Are we going to look at graphs until a bar reaches a red line indicating that a critical threshold is reached? If that's the case, why not create an alert that will trigger under the same conditions and stop wasting time staring at screens and waiting until something happens. Instead, we can be doing something more useful (like staring Netflix).
