Advanced guide to dashboard design principles, KPI selection, visual hierarchy, color usage, and creating dashboards that drive action.
Dashboard Design Principles
1. Purpose-Driven Design
- Define clear objectives before building
- Identify your target audience
- Focus on actionable insights
- Avoid information overload
2. Visual Hierarchy
- Most important metrics at top-left
- Use size and color to emphasize priority

- Maintain consistent spacing
KPI Selection Strategy
Key Questions to Ask:
- What decisions will this dashboard support?
- Who will use this dashboard daily?
- What actions should users take based on the data?
- How often do these metrics need updating?
KPI Categories:
- Operational: Daily performance metrics
- Tactical: Weekly/monthly trend analysis
- Strategic: Long-term business objectives

Layout Best Practices
Grid System
- Use consistent grid alignment
