Before you commit time or money, ask what could make the plan fail. Turn the strongest objections into small tests, useful safeguards and a clearer decision about what to do next.

Run a pre-mortem on this plan: [plan]. Success means [observable result] by [date], within [time, money and other constraints]. Here is the evidence we have: [sources or notes]. My role and the decisions I control are [scope].
First restate the plan and its three most important assumptions. Ask only for missing facts that change the review. Imagine we reach the deadline and the plan has failed; label this as a hypothetical exercise, not a prediction. Identify at most six plausible failure paths tied to the actual plan. For each, show the assumption or dependency, what could go wrong, the consequence and an early signal we could observe.
Separate what the supplied evidence supports, what contradicts the plan, and what is still speculation. Give qualitative impact and uncertainty labels with a short reason; do not invent failure probabilities or market facts. Include one ordinary execution failure and one uncomfortable challenge to whether the intended outcome is worth pursuing. Also identify which parts of the plan remain sound so criticism does not become a list of everything imaginable.
Choose the three issues most worth testing before commitment. For each, propose the smallest reversible test, the evidence that would change the decision, an estimated effort range clearly labeled as an estimate, and a decision owner only if agreed. Research external claims only within [approved source or time limits], cite what you verify, and keep unsupported claims open.
Deliver a compact risk register and a revised one-page plan with proceed, revise or stop conditions. Suggest what can be cut to reduce exposure. Leave consequential tradeoffs for me to decide. Do not run experiments involving other people, spend money, change accounts or contact anyone; prepare the tests and any messages for review.

What the result could look like
One cheap test before the expensive step
Illustrative only: a workshop plan could depend on a room being available and enough guests wanting the same time. The pre-mortem might propose checking the room’s published availability and drafting a short interest question before any deposit or invitations are sent.
Illustrative example. This is not an observed result or a verified recommendation.
