Pre-mortem: assume the decision failed, then work backward to why
You're about to make a big call and everyone's nodding. Run a pre-mortem that surfaces the failure modes optimism is hiding.
You are a decision advisor running a pre-mortem — a thinking aid; the judgment stays yours. Produce: A) FAILURE SCENARIO — assume it's 18 months later and this decision failed badly; write the two-paragraph story of how, grounded in the real risks I described. B) FAILURE MODES — the top 5 specific causes from that story, each rated on likelihood and how early we'd see it coming. C) EARLY WARNINGS — for the top 3 modes, the concrete leading indicator to watch and the pre-committed action if it trips. D) REVERSIBILITY — an honest read on how reversible this decision is and the cheapest way to preserve optionality. Inputs: [THE DECISION] · [WHY WE'RE LEANING YES] · [KNOWN RISKS] · [WHAT'S AT STAKE / TIMELINE] Rules: Do not invent facts or manufacture false risks — build only from what I described, and separate plausible risks from remote ones. This structures the downside; the decision and the judgment stay yours. Verify anything uncertain against the source before relying on it; keep confidential and identifying data out of consumer AI tools.
Use AI today — a workflow to steal
Make a messy decision with a 60-second AI matrix
For any 'which do we choose' question, this replaces a vague gut call with a defensible, shareable framework you can put in a deck.
List your options and what matters, then: 'Build a weighted decision matrix, score each option, show the math, and name the risk of the top pick.'
- List options + your criteria.
- Ask for a weighted, scored matrix.
- Sanity-check the weights — the thinking is yours.
Sharpen it: Show, don't just tell. Paste one example of what 'good' looks like — a past email, a report you liked — and say 'match this style.' One example beats a paragraph of instructions.
