You land in a project. No docs. Everything already built. People arguing over what’s global, what’s local. You’re supposed to help. Where do you start?
You reverse engineer.
What It Means
You take what already exists — data, screens, test cases, change logs — and reconstruct how the system actually works. Not how someone said it should.
You trace:
Where fields appear
How they behave
Who touches them
What breaks when they change
You turn unknowns into a structure. Not perfect — usable.
Core Principles
Don’t trust documentation. Trust behavior.
Every field is a lead. Follow it.
Ownership is visible in who reacts, not who’s listed.
Repeating patterns = implied logic.
Unknown? Flag it. Silence = risk.
Fact vs. Fiction: Accept the Gaps
Often, what was planned doesn’t match what exists. Reverse engineering isn’t just about rebuilding a map — it’s about showing where reality diverged from intention.
Create a Gap Matrix:
| Function / Field | In Plan? | Exists in System? | Risk | Comment |
| ZZ_REGION_CODE | ✅ | ❌ | 🟥 | Missing in staging UI, rollouts blocked |
Document these deltas. Use them in meetings. Avoid testing things that were never built.
