80% of dashboards I'm asked to fix have the same problem: they answer questions nobody is asking. The CEO doesn't care about 47 KPIs. She cares about 3 numbers that tell her if next quarter will hit target.
My 4 rules: 1) One screen = one decision. 2) Big numbers first, charts second. 3) Filter by stakeholder role on load. 4) Annotate the why — not just the what.
I design Power BI dashboards that survive past the launch demo. If your last dashboard project ended in screenshots emailed once a week, you don't need more data — you need a better story.
