The idea
The car dashboard
A car's dashboard shows speed, fuel, temperature and warning lights. It does not show the engine's design or the history of every journey.
It shows the handful of numbers the driver must act on, all at once, at a glance. Everything else is deliberately absent.
A data dashboard is the same idea for an organisation, and most bad dashboards fail by putting the engine design on the windscreen.
Check against your class slides. No Power BI material exists in the export, so this chapter is built from the Camm textbook and the class's own case documents.
