SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill challenges overly optimistic or biased judgments by revealing missing assumptions, hidden variables, execution costs, timing delays, and asymmetric downside risks so decisions are grounded in more realistic scenarios.

Core Features & Use Cases

  • Assumption Discovery: Identify the single most vulnerable assumptions underpinning a proposal or forecast.
  • Scenario Comparison: Compare optimistic, base, and failure scenarios and specify the conditions that change acceptability.
  • Mitigation & Alternatives: Propose at least one actionable, safer alternative or phased rollout plan and define re‑evaluation triggers.
  • Use Case: Useful for product roadmaps, project plans, investment theses, and high-stakes operational decisions.

Quick Start

Review the attached proposal and list its top three vulnerable assumptions, compare optimistic, base, and failure scenarios, and recommend at least one safer alternative with conditions for reconsideration.

FAQPage Schema
How do I identify hidden assumptions and downside risks in a project proposal?

Risk assessment identifies hidden assumptions by evaluating missing variables, execution costs, and timing delays in proposals. It reveals vulnerable assumptions and asymmetric downside risks to ground decisions in realistic scenarios.

When do I need to apply a reality check to my product roadmap or decision review?

Apply a reality check to product roadmaps and decision reviews when scenarios appear under-tested or selectively framed. It challenges overly optimistic judgments by exposing missing variables and asymmetric downside risks before approval.

How do I compare optimistic, base, and failure scenarios for investment theses?

Scenario planning compares optimistic, base, and failure scenarios by specifying the conditions that change acceptability. It evaluates investment theses and high-stakes decisions to deliver a prioritized list of vulnerable assumptions.

Can I use assumption analysis to mitigate bias in high-stakes operational decisions?

Assumption analysis mitigates bias in high-stakes operational decisions by challenging selectively framed proposals. It reveals timing delays and execution costs to deliver actionable mitigation or staged alternatives with clear reconsideration conditions.

What is the best way to propose actionable alternatives for vulnerable project assumptions?

The best way to propose actionable alternatives is to define a phased rollout plan with explicit re-evaluation triggers. This approach establishes safer alternatives while maintaining clear conditions for future reconsideration.
