A gated process, and a record of it.

Requirements become testable acceptance criteria

Before anything is built, what you asked for is written down as conditions that can be checked — not adjectives. "Prices update correctly" becomes a specific, verifiable statement about what happens to which products under which conditions. This is where most misunderstandings surface, and it is much cheaper to find them here.

Important work is reviewed in a fresh context

Work gets reviewed again from a clean slate, without the assumptions that built it. Someone deep in a problem stops seeing it; a review that starts cold catches what a second pass by the same tired eyes will not.

Tests and live verification are recorded

Automated tests run, and the system is exercised against real conditions rather than only in theory. Those runs are recorded, so "it was verified" points at a specific result you can look at instead of a claim you have to take on faith.

Irreversible production changes require human approval

Nothing that can't be undone happens automatically. When a change is about to write to a live catalog, delete something, or touch production data, it stops and waits for a person to approve it. Where it's practical, the system takes a snapshot first so the change can be rolled back.

You get a quality record you can read

At handoff you receive a plain-language record of what was built, what was tested, what was verified, and what is known to be outstanding — written to be read by whoever signs off, not only by an engineer. If you later hand the system to another developer, that record travels with it.

What I don't claim

I'm not going to tell you this is faster than another firm, or that it produces fewer defects. I haven't measured it against a controlled alternative, so I'd be making the number up, and you'd have no way to check it. I'm currently instrumenting real projects to find out.

What I will tell you is exactly what the process does and what evidence you get at the end — and you can hold me to that, because all of it is checkable. If a provider gives you a percentage without telling you what it was measured against, ask.
