Designing executive dashboards leaders actually use
The design principles behind executive dashboards that reach the C-suite and stay there.

Executive dashboards fail for a predictable reason. They are built to display everything the data warehouse can produce rather than the handful of decisions a leadership team actually makes each month.
Begin with the decision, not the dataset. Ask which recurring choices the dashboard should inform, who makes them, and on what cadence. Every visual that does not support one of those choices is a candidate for deletion.
Limit the top view to the small number of measures that describe the health of the business. If a leader cannot read the page in under a minute, the design has failed regardless of how sophisticated the model behind it is.
Give every metric a single, documented definition. Most disputes in a review meeting are not about performance but about whether two teams counted the same thing the same way. Agreeing definitions is unglamorous and enormously valuable.
Show direction, not just position. A number without a trend, a target or a comparison invites the question of whether it is good news, which wastes the first ten minutes of the meeting.
Push detail into layers. Keep the summary clean and let users drill through to the operational view when they want the underlying records. Detail should be available on demand rather than crowded onto the front page.
Treat performance as a design requirement. Slow pages get abandoned quietly. Model the data properly, pre-aggregate what you can, and test with realistic volumes before rollout rather than after.
