Dashboard Design Brief

Help me write a complete design brief for a data dashboard.

**Purpose of the dashboard:**
[What question does someone answer by looking at this dashboard?]

**Primary users:**
- Who uses it: [e.g. sales managers, executives, analysts, customer success team]
- How often: [e.g. daily, weekly, real-time monitoring]
- Their data literacy: [Comfortable with data / needs plain language / power users]

**Key decisions this dashboard supports:**
[What will users do differently because they looked at this?]

**Metrics to include:**
[List what you think should be on it — or describe the business area and let me suggest]

**Data sources:**
[Where the data comes from — e.g. Salesforce, PostgreSQL, Google Analytics, Mixpanel]

**Tool:**
[e.g. Tableau, Looker, Metabase, Power BI, Grafana, custom React]

**Constraints:**
[Any technical, design, or organizational constraints]

Write a dashboard brief covering:
1. **Dashboard purpose statement** — one sentence on what this dashboard does and for whom
2. **Layout recommendation** — how to organize sections (above/below the fold, tabs, filters)
3. **Metric inventory** — every metric to include, with: name, definition, chart type, update frequency, and priority (must-have / nice-to-have)
4. **Interactivity requirements** — filters, drill-downs, time range selectors needed
5. **Design principles** — color, density, and hierarchy guidelines for this audience
6. **What to leave out** — metrics that seem relevant but shouldn't be on this dashboard
