SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematically identifies weaknesses in plans before they fail in the real world, helping teams convert risk into actionable guardrails rather than discarding purpose.

Core Features & Use Cases

  • CORE ASSUMPTIONS extraction & rating: surface every assumption, categorize by domain (market, execution, customers, competition, finance), and assign confidence and impact.
  • VULNERABILITY MAP production: map high-risk bets using a risk matrix and identify the strongest dependencies and the weakest links.
  • DEPENDENCY CHAIN and REVERSIBILITY planning: trace how assumptions cascade to outcomes and define reversible vs irreversible actions with contingency steps.
  • Deliverable and governance: output a structured Challenge Report with sections like CORE ASSUMPTIONS, VULNERABILITY MAP, DEPENDENCY CHAIN, REVERSIBILITY ASSESSMENT, KILL SWITCHES, HARDENING ACTIONS.
  • Applicable scenarios: suitable for product roadmaps, GTM plans, hiring plans, and fundraising plans to validate viability before committing resources.

Quick Start

Provide the plan name and run /em:challenge to generate a vulnerability map.

FAQPage Schema
What is a pre-mortem analysis and how does it surface risks in a plan?

A pre-mortem analysis systematically extracts core assumptions from a plan, categorizes them by domain, and maps high-risk vulnerabilities before real-world execution. This process converts potential failures into actionable guardrails and structured risk assessments.

How do I stress-test a go-to-market plan before committing resources?

Provide your go-to-market plan name to generate a Challenge Report. This report traces dependency chains, assesses action reversibility, defines kill switches, and recommends hardening actions to validate viability before resource commitment.

Can I use pre-mortem risk analysis for hiring and fundraising plans?

Yes, pre-mortem risk analysis applies to hiring plans and fundraising plans. It surfaces vulnerabilities by rating confidence and impact across execution, market, customer, competition, and finance domains to guide decision-ready assessments.

What's the best way to identify which assumptions pose the highest risk to a product roadmap?

The best way to identify high-risk assumptions is generating a vulnerability map. This risk matrix highlights the strongest dependencies and weakest links, rating each assumption by confidence and impact to prioritize hardening actions.

How do I plan contingency steps when an irreversible decision fails during execution?

To plan contingency steps for irreversible decisions, conduct a reversibility assessment. This traces how assumptions cascade into outcomes, distinguishes reversible from irreversible actions, and defines specific kill switches to halt failure.

When should I not use a pre-mortem to validate plan viability?

Avoid using a pre-mortem when a plan lacks defined core assumptions or dependency chains. Without structured inputs across market, execution, or finance domains, the vulnerability map cannot accurately surface risks or generate meaningful hardening actions.
