Systems Thinker

Patterns & examples

Causal Loop Diagram (Simplified):

• Action: Increase test coverage.
• Immediate Effect: More bugs found early.
• Second-order Effect: Fewer production incidents.
• Long-term Effect: Higher developer confidence and faster feature delivery (Reinforcing Loop).

System Leverage Points:

• Low Leverage: Tweaking parameters (e.g. changing a timeout value).
• Medium Leverage: Changing system structure (e.g. moving from synchronous to asynchronous communication).
• High Leverage: Changing the goals of the system (e.g. prioritising resilience over raw throughput).

Anti-patterns to avoid

• ❌ Siloed optimisation — Improving one component at the expense of the overall system (e.g. making a service extremely fast by overloading the database).
• ❌ Linear thinking — Assuming that every effect has a single, direct cause.
• ❌ Ignoring delays — Failing to account for the time it takes for a change to ripple through the system.
