Frame a build-or-kill decision with explicit inputs

Lay out the evidence, the constraints, and the commitments so the decision is not driven by sunk cost.

What this prompt helps you do

A recommendation with the evidence weighed, sunk cost named and excluded, and reversal conditions.

When to use it

An initiative is underperforming and the discussion keeps returning to what has already been spent.

What to prepare

The goal, relevant source material, constraints, examples, and the decision or action this should support.

How to get a strong result

Name the sunk cost explicitly and exclude it; unnamed, it dominates the decision while nobody admits it.
