Project KPI Dashboard
Business Case
Problem Statement
Project stakeholders struggle with:
-
Scattered data across multiple systems
-
Delayed reporting on project health
-
No real-time visibility into KPIs
-
Inconsistent metric definitions
Solution
Centralized KPI dashboard that aggregates data from multiple sources and presents key metrics with drill-down capabilities.
Business Value
-
Real-time visibility - Live project health status
-
Data-driven decisions - Actionable insights
-
Stakeholder alignment - Single source of truth
-
Early warning - Proactive issue detection

Quick Start
from datetime import date
Configure dashboard
config = DashboardConfig( project_name="Office Tower Construction", project_code="PRJ-2024-001", start_date=date(2024, 1, 1), end_date=date(2025, 12, 31), budget=50000000, currency="USD" )
Initialize dashboard
dashboard = ProjectKPIDashboard(config)
Calculate schedule KPIs
dashboard.calculate_schedule_kpis( planned_activities=100, completed_activities=85, planned_duration_days=180, actual_duration_days=195 )
Calculate cost KPIs
dashboard.calculate_cost_kpis( budgeted_cost=25000000, actual_cost=24500000, earned_value=24000000 )
Get summary
summary = dashboard.get_dashboard_summary() print(f"Overall Health: {summary['overall_health']}")
Common Use Cases
- Weekly Executive Report
df = dashboard.export_to_dataframe() critical = df[df['Status'] == 'critical'] print(f"Critical KPIs requiring attention: {len(critical)}")
- Trend Analysis
Get historical data for a metric
spi_history = [h for h in dashboard.history if h['name'] == 'Schedule Performance Index']
- Multi-Project Dashboard
projects = [] for project_config in project_configs: dash = ProjectKPIDashboard(project_config) # ... calculate KPIs projects.append(dash.get_dashboard_summary())
