4SR
The pattern of process revision emerged while I was mapping theoretical solutions.

Different fields, same underlying loop.
After years of working across software QA, auditing, validation, and AI governance, something started to click.
The terms change. The artifacts change. The tools definitely change.
But the process underneath? It barely does.
Whether you’re assessing a clinical system, tracing data lineage, auditing controls, or reviewing an AI workflow, the work still follows the same rhythm:
Observe -> Interpret -> Report -> Revise
I’ve call it 4SR — Four-step Revision.
It’s a simple way to bring complex systems into alignment:
1 Observe - Look closely at the current state
2 Interpret - Make sense of the structure, intent, and gaps
3 Report - Verbally and visually record your findings
4 Revise - Improve on the process
Then you start again.
The idea is inspired by John Boyd’s OODA loop - Observe, Orient, Decide, Act — a framework for adaptive thinking. While I was playing with mapping processes the other night I started to notice the Four-step Revision pattern emerge from every solution I was theorizing.
4SR takes that same adaptive logic of OODA and applies it to governance, auditing, and validation work. The goal isn’t just to decide; it’s to align, to bring messy systems back into clarity, integrity, and reliability.
In the end, every discipline has its own language. But underneath it all is the same motion - continuous revision toward better understanding.
Sometimes progress isn’t about inventing a new process.
It’s about finally seeing the one that was there all along.
