Think in Systems — Interactive Mindmaps

Key concepts: 1. The Beginning

1. The Beginning

Your Life as a System

• Picture your life expanding into an infinite network
• Problems are interconnected, not isolated events
• Systems thinking reveals levers that actually move things

The Scrambled Eggs Principle

• Everyday routines are small systems you can tweak
• You don't need to invent systems, just improve them
• Changing inputs (like adding cheese) changes outputs
• Practice on small systems to spot complex ones later

Borrowing Existing Systems

• Apply proven models from one domain to another
• Supply-and-demand explains job hunting dynamics
• Structural imbalances, not personal failings, cause stuckness
• Two options: compete harder or change the supply side

The Romeo Question

• Ask: Am I trying to win as the supply?
• Decide between competing harder or finding less competition
• Cuts through noise in job hunting, dating, or negotiations
• Removes guesswork, not the work itself

Small Inputs, Big Leverage

• Small repeated inputs hide leverage over big outcomes
• Waking routine and self-talk shape energy and mood
• Break your life into smaller sub-systems to improve
• Start by noticing one small input to change this week

Key concepts: 2. Elements of Systems Thinking

2. Elements of Systems Thinking

Three Components of Any System

• Elements: visible actors like people or objects
• Interconnections: flows of information and signals
• Function/purpose: deduced from behavior, not claims

Key Concepts for Systems Vocabulary

• Interconnectedness: everything relies on something else
• Synthesis: understanding wholes, not just parts
• Feedback loops: reinforcing amplifies, balancing stabilizes
• Causality vs. correlation: avoid mistaking one for other

Emergence and Circular Thinking

• Emergence: new properties arise from component combinations
• Systems thinking shifts from linear to circular perspective
• Examples: cake from ingredients, frog from tadpole

Iceberg Model for Deep Diagnosis

• Event level: visible tip of the problem
• Patterns: recurring events over time
• Structure: policies, organizations, or rituals
• Mental models: beliefs and values sustaining structure

Practical Application of Frameworks

• Pair iceberg model with three-component framework
• Gain vertical depth and horizontal structure
• Reveals why surface-level fixes often fail

Key concepts: 3. How Do Systems Work?

3. How Do Systems Work?

Order of Impact in Systems

• Elements are most visible but least powerful
• Interconnections reshape behavior when changed
• Purpose is the heavyweight that transforms everything
• Fix purpose first, then interconnections, then elements

Stocks and Flows

• Stocks are measurable quantities at a given moment
• Flows are actions that change stocks over time
• Stocks act as memory, holding history of flows
• Stocks change slowly, setting system's rhythm

The Systems Thinker's Blind Spot

• People focus on stocks, not flows
• Most think only about increasing inflow
• Slowing outflow can also grow a stock
• This blind spot is where systems thinkers gain edge

Reinforcing Feedback Loops

• Reinforcing loops drive exponential growth or decay
• Savings account interest is a classic example
• The loop feeds itself and accelerates change
• More wolves lead to more pups, then more wolves

Balancing Feedback Loops

• Balancing loops push system toward a target
• Thermostat maintains temperature via cooling/heating
• Beneficial bacteria keep harmful bacteria in check
• These loops create stability and equilibrium

Three Questions to Test Models

• Will driving factors really play out as assumed?
• Will the system react as expected if they do?
• What outside forces nudge the driving factors?
• These questions keep your model honest

Delays and Oscillation

• Delays cause systems to overshoot and correct
• Thermostat wobbles because heat escapes faster
• Information delays include perception and response
• Airlines oscillate chasing a slipping sweet spot

Key concepts: 4. Bottlenecks, Leverage, and Feedback Loops

4. Bottlenecks, Leverage, and Feedback Loops

The Bottleneck Principle

• Every system has one tightest constraint
• Fixing anything else won't move the needle
• Don't confuse symptoms with bottlenecks
• Old beliefs can be hidden bottlenecks

High-Leverage Moves

• Find the 20% effort producing most results
• Change the rules of your system
• Build self-organization for automatic improvement
• Improve information flow with shorter feedback loops

The Improvement Cycle

• Name the real bottleneck, not just symptoms
• Apply one precise leverage point
• Set up a fast feedback signal to measure
• Repeat as the bottleneck shifts
