For tinkerers & generalists
You don't need to know the system.
You need a process.
A four-step method for diagnosing anything unfamiliar — a boat that won't charge, a bike that won't idle, a network that's gone quiet. Built by a career troubleshooter across seven completely different fields.
Most troubleshooting advice is a lookup table.
Symptom on the left, fix on the right. It works exactly once — on the system it was written for. The moment you're standing in front of something unfamiliar, the table is useless, and memorizing fixes gets you nowhere. The Diagnose Anything Method teaches the process underneath every fix, so it doesn't matter what the system is.
The Diagnose Anything Method
Investigate
Gather signal before touching anything. What's actually happening — not what you assume?
Assess
Separate confirmed fact from assumption. What's genuinely abnormal vs. just how this system behaves?
Theorize Expected Operation
Build an explicit model of how the system is supposed to work — the step most people skip.
Gap Analysis
Compare your model to reality. The exact point they diverge is where the fault lives.
Proven across seven completely different fields
If the same method holds up from a jammed copier to a live broadcast facility to an AI-driven security remediation pipeline, it isn't a job skill. It's a way of thinking.
- Photostatic copiers
- Live radio broadcast
- Enterprise networks
- Cybersecurity incident response
- AI-driven remediation
- Boats & motorcycles
- 3D printers & home projects
