name: dashboard-specification description: Design specifications for effective dashboards. Use when planning new dashboards, improving existing ones, or documenting dashboard requirements before development.

Dashboard Specification

Quick Start

Create comprehensive dashboard specifications that clearly define metrics, layout, interactivity, and user needs before development begins.

Context Requirements

1. Purpose: What decisions will dashboard support
2. Users: Who will use it and how often
3. Metrics: KPIs and supporting metrics needed
4. Data Sources: Where data comes from
5. Refresh: How often data updates

Context Gathering

"To spec your dashboard, I need:

• Primary use case (what decisions?)
• Users (roles, frequency, tech-savviness)
• Must-have metrics vs nice-to-have
• Data availability and freshness
• Any existing dashboards to replace/improve"

Workflow

Step 1: Define Dashboard Purpose

Copyfrom datetime import datetime

class DashboardSpec:
    def __init__(self, name, purpose):
        self.name = name
        self.purpose = purpose
        self.target_users = []
        self.use_cases = []
        self.metrics = []
        self.data_sources = []
        self.layout = None
        
    def add_user_persona(self, role, frequency, use_case):
        self.target_users.append({
            'role': role,
            'frequency': frequency,
            'use_case': use_case
        })
    
    def add_metric(self, name, definition, calculation, importance):
        self.metrics.append({
            'name': name,
            'definition': definition,
            'calculation': calculation,
            'importance': importance  # primary, secondary
        })
    
    def add_data_source(self, source, tables, refresh):
        self.data_sources.append({
            'source': source,
            'tables': tables,
            'refresh': refresh
        })

# Initialize
spec = DashboardSpec(
    name="Revenue Performance Dashboard",
    purpose="Monitor daily revenue performance, identify trends, and track against targets"
)

spec.add_user_persona(
    role="VP Sales",
    frequency="Daily (morning)",
    use_case="Check if on track for monthly target, identify at-risk deals"
)

spec.add_user_persona(
    role="Sales Reps",
    frequency="Multiple times daily",
    use_case="Track personal performance, pipeline health"
)

print(f"✅ Dashboard spec started: {spec.name}")

Step 2: Define Metrics Hierarchy

Copy# Primary metrics (hero numbers)
spec.add_metric(
    name="MTD Revenue",
    definition="Total revenue closed month-to-date",
    calculation="SUM(deal_value) WHERE close_date >= start_of_month AND status = 'closed_won'",
    importance="primary"
)

spec.add_metric(
    name="Revenue vs Target",
    definition="Actual MTD revenue compared to monthly target",
    calculation="(MTD_revenue / monthly_target) * 100",
    importance="primary"
)

# Secondary metrics (supporting context)
spec.add_metric(
    name="Win Rate",
    definition="% of opportunities won this month",
    calculation="COUNT(won) / COUNT(total_opps) * 100",
    importance="secondary"
)

spec.add_metric(
    name="Average Deal Size",
    definition="Mean value of deals closed MTD",
    calculation="AVG(deal_value) WHERE status = 'closed_won'",
    importance="secondary"
)

print(f"✅ Metrics defined: {len(spec.metrics)}")

Step 3: Design Information Architecture

Copydef design_dashboard_layout(metrics, user_priority):
    """
    Create hierarchical layout based on user needs
    """
    
    layout = {
        'hero_section': {
            'size': 'large',
            'position': 'top',
            'metrics': []
        },
        'trend_section': {
            'size': 'medium',
            'position': 'middle_left',
            'charts': []
        },
        'breakdown_section': {
            'size': 'medium',
            'position': 'middle_right',
            'charts': []
        },
        'detail_section': {
            'size': 'small',
            'position': 'bottom',
            'tables': []
        }
    }
    
    # Primary metrics → Hero section
    for metric in metrics:
        if metric['importance'] == 'primary':
            layout['hero_section']['metrics'].append({
                'metric': metric['name'],
                'display': 'KPI card with sparkline'
            })
    
    # Trends
    layout['trend_section']['charts'] = [
        'Daily revenue trend (30 days)',
        'Revenue by product line (trend)',
        'Pipeline conversion funnel'
    ]
    
    # Breakdowns
    layout['breakdown_section']['charts'] = [
        'Revenue by sales rep (bar)',
        'Win rate by region (map)',
        'Deal size distribution (histogram)'
    ]
    
    # Details
    layout['detail_section']['tables'] = [
        'Top 10 deals closed MTD',
        'At-risk pipeline deals'
    ]
    
    return layout

spec.layout = design_dashboard_layout(spec.metrics, 'VP Sales')
print("✅ Layout designed")

Step 4: Define Interactivity

Copydef specify_interactions(layout):
    """Define filters, drill-downs, and actions"""
    
    interactions = {
        'global_filters': [
            {'filter': 'Date Range', 'default': 'MTD', 'options': ['MTD', 'QTD', 'YTD', 'Custom']},
            {'filter': 'Region', 'default': 'All', 'options': ['All', 'North America', 'EMEA', 'APAC']},
            {'filter': 'Product', 'default': 'All', 'options': ['All', 'Product A', 'Product B', 'Product C']}
        ],
        'drill_downs': [
            {'from': 'Revenue by Region', 'to': 'Revenue by Sales Rep'},
            {'from': 'Pipeline chart', 'to': 'Individual deals in stage'}
        ],
        'click_actions': [
            {'element': 'Deal in table', 'action': 'Open deal details in CRM'},
            {'element': 'Sales rep name', 'action': 'Filter to rep performance'}
        ],
        'hover_tooltips': [
            {'chart': 'All charts', 'show': 'Exact values, % change, vs target'}
        ]
    }
    
    return interactions

interactions = specify_interactions(spec.layout)
print("✅ Interactivity specified")

Step 5: Document Data Requirements

Copy# Data sources
spec.add_data_source(
    source="Salesforce CRM",
    tables=["Opportunity", "Account", "User"],
    refresh="Real-time (15 min)"
)

spec.add_data_source(
    source="Finance Database",
    tables=["revenue_targets"],
    refresh="Daily at midnight"
)

def create_data_model_spec():
    """Document required data model"""
    
    model = """
    ## Required Data Model
    
    ### Fact Table: deal_facts
    - deal_id (PK)
    - close_date
    - deal_value
    - status (closed_won, closed_lost, open)
    - sales_rep_id (FK)
    - product_id (FK)
    - region
    
    ### Dimension: sales_reps

    - target_revenue
    - target_deals
    """
    
    return model

data_model = create_data_model_spec()
print("✅ Data model documented")

Step 6: Generate Complete Specification

Copydef generate_dashboard_spec(spec):
    """Create comprehensive dashboard specification document"""
    
    doc = f"# Dashboard Specification: {spec.name}\n\n"
    doc += f"**Purpose:** {spec.purpose}\n\n"

        doc += f"- Tables: {', '.join(source['tables'])}\n"
        doc += f"- Refresh: {source['refresh']}\n\n"
    
    return doc

full_spec = generate_dashboard_spec(spec)

with open('dashboard_spec.md', 'w') as f:
    f.write(full_spec)

print("✅ Complete specification generated: dashboard_spec.md")

Context Validation

• User needs clearly defined
• Metrics have clear definitions
• Data sources confirmed available
• Refresh frequency realistic
• Layout prioritizes most important info
• Interactivity serves user goals

[Visual wireframe showing KPI cards, trend charts, breakdown charts, detail tables]

## Interactivity

**Filters:** Date range, Region, Product
**Drill-downs:** Region → Rep → Deal
**Actions:** Click deal → Open in CRM

## Data Requirements

**Sources:**
- Salesforce (real-time, 15 min lag)
- Finance DB (daily refresh)

**Tables:**
- Opportunity, Account, User
- revenue_targets

## Success Metrics

Common Scenarios

Scenario 1: "Design new executive dashboard"

→ Focus on high-level KPIs → Minimize interactions → Automated insights → Mobile-friendly → Static screenshots for offline use

Scenario 2: "Improve existing dashboard"

→ Audit current usage → Interview users → Identify pain points → Simplify, don't add → A/B test changes

Scenario 3: "Self-service analytics dashboard"

→ Flexible filters → Export capabilities → Saved views → Drill-downs → Comprehensive documentation

Scenario 4: "Operational dashboard for daily use"

→ Real-time data → Alerting for anomalies → Fast load times → Mobile optimization → Offline capability

Handling Missing Context

User wants "everything": "Let's prioritize:

• What's the #1 question to answer?
• What would you check first?
• What drives decisions? Start with MVP, iterate."

Unclear on users: "Different users need different dashboards:

• Executives: High-level, strategic
• Managers: Team performance
• ICs: Personal metrics, details Who's the primary audience?"

No data model: "I'll help design the data structure:

• What facts do we measure?
• What dimensions for slicing?
• What grain/granularity? Then map to available data."

Advanced Options

Dashboard Generator: Auto-create from specification

Usage Analytics: Track what users actually view

Progressive Enhancement: Start simple, add based on usage

A/B Testing: Test layout variations

Personalization: Customized views per user
