One-size dashboards are a myth. Build three layers: Outcome for execs (telescope), Driver for teams (levers), Deep Dive for analysts (microscope). AI enriches layers, it doesn’t flatten them. The aim isn’t more charts; it’s scaling clear decisions at the right altitude. Make layers reduce noise. Go!

Think like a doctor, not a data collector. Your dashboards should be a cockpit, not a buffet. Every metric has a cost in attention, fueling debate and cognitive load. Track only what informs decisions. If a number doesn't drive action, it's just noise.

In the Data Delusion, we focus on metrics while losing sight of what truly matters. We celebrate tiny, irrelevant wins, creating an illusion of progress. Data without human judgment is just noise – it's time to use it to sharpen our questions, not just track our speed.
