Think Premortem

Category: Sales  ·  Sub-category: prospecting  ·  Last updated:
Prospective failure imagination for a plan, decision, or running system. Operates in two modes — **plan mode** (a plan has not yet been committed to; imagine its catastrophic failure broadly) and **scenario mode** (a specific catastrophic scenario is posed against an existing system; investigate causes against the actual code and architecture). Spawns parallel pre-mortemers in isolation across three categories of lens: standard failure classes (technical, operational, estimation, scope, adoption, dependency, team, incentive, detection, reversibility, adversarial), 0-3 ad-hoc target-specific lenses the orchestrator names when warranted, and a first-principles lens that always runs to catch what the prescribed taxonomy misses. Synthesizes into a prioritized risk register with early-warning signals. Produces feedback only — no code, no tickets, no artifacts.

From the source SKILL.md

Imagines a catastrophic failure has already happened and works backward to the causes. Uses the same Nominal-Group-Technique pattern as the rest of the /think-* namespace: parallel pre-mortemers, each in a different failure-class lens, generating in isolation. The orchestrator synthesizes into a prioritized risk register with early-warning signals the user can act on.
