Efficiency - Reuse - Do you create a report whenever you need a number from a system?

Whenever you need a number from a system you should think of how you can create a report, so next time you can press a button to get the result.

If you found yourself doing ad-hoc reports, or random SQL queries, a few years ago, the best thing to do was to make sure the boss knows you could not find the data you needed, so he could commission a new report to be built.

Since 2015, the best practice is instead to jump into Power BI and build the report yourself.

See Ulysses' video on how Power BI is the best tool for this:
