What this is
A public thinking system focused on how product decisions are made under constraints.
Most notes are evolving — not final.
If you only read three things
Start here, in this order:
- Problem Framing — how I define the right problem before solving it
- Helper Match SG - Case Study — a full product thinking walkthrough on a real problem
- Product Management as a System — how PM actually works beyond the textbook model
Suggested paths
Depending on what you’re looking for:
If you’re evaluating me as a product manager
If you want to understand my mental models
If you want to explore ideas
- Browse the Projects section
- Follow links between related nodes
- Use the graph to discover connections
How this system works
Each note represents one idea.
- Ideas are versioned, not overwritten
- When thinking changes, I record:
- what changed
- why it changed
- Earlier versions are preserved — so the reasoning remains visible
This means you are not just seeing what I think,
but how I arrived there.
How to read individual notes
Each note typically includes:
- Core Idea — what the idea is
- State of Thinking — current understanding
- Thinking Trace — how I arrived there
- What changed / Why it changed — evolution over time
You don’t need to read everything — scanning is fine.
Final note
This system is designed to be:
- honest rather than polished
- evolving rather than complete
- useful over time rather than immediately
If something feels unfinished, it probably is —
and that’s intentional.
