The default urge is to create as many reports & dashboards as possible because it looks like more data & information equals more visibility and insights.

But, that is not how it works. What works wonderfully well is trying not to have many (or any) reports at all. Seriously, try to avoid making them for as long as possible and delete the requirements for them as much as possible. Consolidate what you need to understand into scores that tell you what's happening.

This leads to a few advantages:

1. You won't waste time behind things you won't really need.

2. You anyway won't be able to ignore or delete what you don't really need.

3. Save a huge amount of mental bandwidth trying to implement a complex system.

4. Save a lot of time and money.

5. Avoid information overwhelm. That's usually what happens even after implementing complex systems.

6. Get everyone focused on what actually matters, instead of distracting them with mostly unnecessary information.

7. Discover who needs to see exactly what kind of data. Not everyone needs all the details, so minimize that too.

So, how much can you remove before you can't anymore?
