Causal Loop Diagrams (CLDs)
Causal Loop Diagrams are powerful tools for understanding complex systems and team dynamics. VDF AI generates interactive CLDs to help you visualize cause-and-effect relationships in your agile processes.
What are Causal Loop Diagrams?
Causal Loop Diagrams show how different variables in a system influence each other through feedback loops. They help identify:
- Reinforcing loops: Cycles that amplify change (positive or negative)
- Balancing loops: Cycles that stabilize the system
- System bottlenecks: Where changes have the most impact
- Unintended consequences: Hidden effects of process changes
How to Generate CLDs
Using Agent Mode (Recommended)
- "Create a causal loop diagram showing how technical debt affects delivery time"
- "Visualize the relationship between team size, communication overhead, and productivity"
- "Show how context switching impacts team velocity and quality"
- "Map the feedback loops in our sprint planning process"
Using Scrum Consultant Tool
- Ask about team dynamics: "What's causing our sprint delays?"
- Request process analysis: "Why is our code quality declining?"
- Explore improvement strategies: "How can we reduce cycle time?"
Reading Causal Loop Diagrams
Diagram Elements
Variables (Nodes):
- Represent key factors in your system
- Can be metrics, behaviors, or conditions
- Connected by arrows showing influence
Arrows and Connections:
- Solid arrows: Direct influence (A affects B)
- Dashed arrows: Indirect or delayed influence
- Arrow thickness: Strength of influence
- + or - signs: Type of influence
Feedback Loops:
- Reinforcing loops (R): Self-amplifying cycles
- Balancing loops (B): Self-correcting cycles
- Loop polarity: Overall effect (positive/negative)
Common CLD Patterns in Agile Teams
Technical Debt Loop:
High Pressure → Rushed Code → Technical Debt → Slower Development → High Pressure
Team Learning Loop:
Knowledge Sharing → Better Practices → Improved Quality → Team Confidence → More Knowledge Sharing
Context Switching Loop:
Multiple Projects → Context Switching → Reduced Focus → Lower Quality → More Rework → Multiple Projects

Best Practices for CLD Generation
Effective Prompts
- Be specific: "Show how WIP limits affect cycle time in our Kanban process"
- Include context: "For a team of 6 developers working on React applications"
- Focus on problems: "Visualize why our sprint commitments are consistently missed"
- Consider timeframes: "Show both short-term and long-term effects"
Common Use Cases
- Sprint Retrospectives: "What patterns caused our last sprint's issues?"
- Process Improvement: "How would adding code reviews affect our delivery?"
- Team Dynamics: "Why is our team velocity inconsistent?"
- Technical Decisions: "What are the long-term effects of this architecture choice?"
Advanced CLD Features
Multi-Loop Analysis
- Primary loops: Main cause-and-effect relationships
- Secondary loops: Supporting or conflicting influences
- Loop interactions: How different cycles affect each other
System Archetypes
- Limits to Growth: Success creates conditions that limit further success
- Shifting the Burden: Quick fixes that don't address root causes
- Tragedy of the Commons: Individual optimization that hurts the group
Dynamic Behavior
- Time delays: Effects that take time to manifest
- Non-linear relationships: Effects that change based on magnitude
- Threshold effects: Changes that only occur above certain levels
Troubleshooting CLDs
Common Issues
- "I don't see a diagram": Ensure you're using Agent mode or Scrum Consultant tool
- "Diagram is too small": Use the "Fit to View" button to auto-resize
- "Export failed": Try refreshing the page and generating the diagram again
- "Missing variables": Be more specific in your prompt about which factors to include
Tips for Better Results
- Start simple: Begin with 3-5 key variables, then expand
- Use team language: Include terms your team actually uses
- Focus on behaviors: Include both technical and human factors
- Consider constraints: Mention limitations like budget, time, or resources
CLD Examples for Agile Teams
Sprint Planning Dynamics
Sprint Pressure → Overcommitment → Rushed Work → Technical Debt → Sprint Pressure
Team Learning and Growth
Knowledge Sharing → Better Practices → Improved Quality → Team Confidence → Knowledge Sharing
Process Improvement
Process Change → Initial Disruption → Learning Curve → Improved Efficiency → Process Change
Quality vs Speed Trade-offs
Delivery Pressure → Reduced Testing → Quality Issues → Rework → Delivery Pressure

- Start with the problem: Focus on the issue you want to understand
- Include all stakeholders: Consider all perspectives and influences
- Test assumptions: Validate relationships with data when possible
- Keep it simple: Begin with essential variables, add complexity gradually
Team Collaboration
