Systems Thinking Evaluation Skill

Evaluate what's working, what isn't, and why in any system — technical, organizational, product, or process.

Core Mental Models

1. System Boundary

What's inside (in scope), outside (environment, dependencies, constraints), where does it begin and end?

2. Stocks and Flows

• Stocks: What accumulates? (users, debt, trust, knowledge, bugs, revenue)
• Flows: What changes those stocks? (acquisition, churn, learning, entropy)
• Where are flows blocked, broken, or leaking?
