Building Your Dashboard
Step 1: Define Your KPIs
Sales Dashboard:
- Daily revenue
- Revenue vs goal
- Active customers
- Pipeline value
- Sales rep performance
- Conversion rates
- Average deal size
Operations Dashboard:
- Support queue
- Response time
- Resolution rate
- Team workload
- Customer satisfaction
- Ticket backlog
- Escalated issues
Marketing Dashboard:
- Website traffic
- Leads generated
- Cost per lead
- Conversion rate
- Campaign ROI
- Email metrics
- Social engagement
Step 2: Create Sheet Structure
Sheet 1: Raw Data
- Minimal processing
- Complete records
- Timestamps
- Source system IDs
Sheet 2: Calculated Metrics
- Formulas for KPIs
- Aggregations
- Ratios and percentages
- Trending data
Sheet 3: Dashboard View
- Charts and visualizations
- Executive summary cards
- Key metrics highlighted
- Drill-down capability
Step 3: Build Data Pipelines
Workflow 1: Daily Metrics
Trigger: Schedule (6 AM, 12 PM, 6 PM)
- Stripe: Daily revenue
- HubSpot: Deals, pipeline
- Analytics: Traffic, conversions
- Support: Open tickets
- Aggregate and append
Workflow 2: Real-Time Alerts
Trigger: Every 5 minutes
Monitor:
- Revenue drops 20%?
- Support queue > 10?
- Site down?
- API errors?
Send: Slack notifications
Step 4: Create Formulas
Daily Revenue:
=SUMIF(D:D, TODAY(), F:F)
Week-over-Week Growth:
=((B2-B1)/B1)*100
30-Day Moving Average:
=AVERAGE(B1:B30)
Rank Performance:
=RANK(B2, $B$2:$B$100, 0)
Step 5: Build Visualizations
Charts that matter:
- Line charts: Trends over time
- Column charts: Comparisons
- Pie charts: Composition
- Gauges: Progress to goal
- Scorecards: Key metrics
- Heat maps: Performance grids
Real-World Example: SaaS Company
Executive Dashboard:
Top Row (KPI Cards):
- Daily Recurring Revenue: $5,234
- Monthly Recurring Revenue: $157,000
- Active Customers: 1,247
- Churn Rate: 2.3%
- Support Satisfaction: 4.8/5
Middle Section (Trends):
- Revenue trend (90-day line)
- Customer growth (trend)
- Feature adoption (stacked bar)
- Churn trend (line)
Bottom Section (Details):
- Revenue by plan tier (pie)
- Customers by region (map)
- Support by category (bar)
- Team performance (table)
Right Sidebar (Alerts):
- High churn alert
- Payment failures
- API incidents
- Feature bugs reported
Advanced Features
Predictive Metrics
Add forecast to your data:
=FORECAST(TODAY(), historical_range, date_range)
Anomaly Detection
Flag unusual values:
=IF(ABS(B2-AVERAGE(B:B))>STDEV(B:B)*2, "⚠️ Anomaly", "✓ Normal")
Conditional Formatting
Highlight important data:
- Top 10% green
- Bottom 10% red
- Goals met blue
- Trends reversed yellow
Performance Optimization
For large datasets (100,000+ rows):
- Archive old data: Move 90-day-old data to archive sheet
- Use tables: Better than ranges for sorting/filtering
- Limit formulas: Avoid complex calculations in every row
- Refresh intervals: Update every 15 min, not every minute
- Delete old data: Keep only necessary columns
