SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Stress-test planning by forcing teams to surface failure modes and plan adjustments before committing to major bets. Through a structured pre-mortem workflow, it helps reveal hidden assumptions, evaluate risk categories, and align the team on next steps.

Core Features & Use Cases

  • Diagnostic mode runs a full pre-mortem session with vivid failure scene-setting, six failure categories, the monkey test, and concrete plan adjustments.
  • Review mode checks previous findings monthly for changed probabilities and new failure modes.
  • Alert Triggers mode defines and monitors early warning signals across four trigger categories.
  • Monkey Test to identify the critical unknowns and design minimal, cost-effective validation experiments.
  • Update to company-context.md with active assumptions, plan adjustments, and session logs for cross-session continuity.

Quick Start

Run a Diagnostic pre-mortem on your plan to surface failure modes and test the monkey assumption.

FAQPage Schema
What is a pre-mortem analysis and how does it help with strategic planning?

A pre-mortem analysis is a risk-management technique that imagines a plan's failure before commitment. This Skill guides a diagnostic session to surface hidden assumptions, evaluate failure modes across six categories, and align teams on plan adjustments.

Can I use this pre-mortem workflow for major commitments like product launches and investments?

Yes, the pre-mortem workflow is designed for major commitments such as product launches, investments, or partnerships. It tracks assumptions, identifies failure modes, and defines monitoring triggers to stress-test these high-stakes decisions.

What is the monkey test in risk management and how do I apply it?

The monkey test identifies the critical unknowns in a strategic plan and designs minimal, cost-effective validation experiments. It is a core component of the diagnostic pre-mortem session used to stress-test your assumptions before commitment.

How do I monitor early warning signals after completing a pre-mortem session?

Use the Alert Triggers mode to define and monitor early warning signals across four trigger categories. You can also run the Review mode monthly to check previous findings for changed probabilities and new failure modes.

What's the best way to track active assumptions across multiple planning sessions?

The Skill automatically updates company-context.md with active assumptions, plan adjustments, and session logs. This provides cross-session continuity and tracks the four response options available in the plan-adjustment framework.
