Over 18 months we logged 80+ real strategic decisions in a decision journal: hiring senior roles, killing product lines, vendor renewals, market expansion, board prep, organizational restructures, and live incident calls. Each decision was attempted with at least one framework paired with Claude (Pro or Team), with the prompt structure, the model output, the human override, and the eventual outcome captured.
We ran A/B comparisons where it was honest to do so. Some decisions got a Claude-assisted treatment and a parallel human-only treatment by a peer operator unaware of the AI involvement. Hit rates and time-to-decision were compared at 90 and 180 days. Where the Claude-assisted approach helped, it usually helped by reducing the time to a defensible call rather than improving the call itself.
The frameworks on this page are the ones that survived the testing. Several frameworks (SWOT, Six Thinking Hats, PESTLE) were tried and dropped because they produced output that read good but did not change the decision in practice. The eight on this page each shifted at least one real call we would otherwise have gotten wrong.
Treat the prompts as starting points, not gospel. The single biggest gain in our testing came from forcing explicit probability ranges and ranked outputs. Open-ended prompts produced fluff; structured prompts produced signal.
