How the Devil's Advocate Board gate works
How the Devil's Advocate Board grades a go/no-go decision: five adversarial lenses weighted into a 0–100 conviction, with a veto gate where any lens scored 1 or 0 forces NO-GO — which is how a 64-conviction case still reads NO-GO when the CFO vetoes the downside.
How the gate works
This tool grades a big go/no-go decision across five adversarial lenses. Each control is marked from your own evidence and weighted into a 0–100 score — and then the score is run past a gate that can only make the verdict worse.
The 5 weighted controls
| Control | Weight |
|---|---|
| The Skeptic · evidence | 22 |
| The Customer · demand | 22 |
| The CFO · downside | 20 |
| The Operator · execution | 18 |
| The Contrarian · kill-shot | 18 |
| Total | 100 |
The verdict bands
Any lens scored 1 or 0 is a fatal objection — it forces NO-GO regardless of the score. A high conviction number cannot outvote a single dealbreaker.
In the worked sample it scores 64 out of 100 and still reads NO-GO — The CFO scored the downside 1 of 5 — a fatal veto — so the board reads NO-GO despite a 64 conviction. The one thing to fix first: Resolve the CFO's downside objection — prove the cost of being wrong is survivable — before anything else..
Common questions
Can something score well on the Devil's Advocate Board and still fail?
Yes. The weighted score is run past a worsen-only gate — the Veto gate — that can only make the verdict worse. In the worked sample it scores 64 out of 100 and still reads NO-GO, because the CFO scored the downside 1 of 5 — a fatal veto — so the board reads NO-GO despite a 64 conviction.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-good score, because a single disqualifying gap shouldn't hide behind a high average. The tool also names the one thing to fix first — here, "Resolve the CFO's downside objection — prove the cost of being wrong is survivable — before anything else.".
A decision stress-test, not a decision-maker. Scores a case you describe; the call is yours.
