SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audits every key assumption and calibrates evidence before signing off on strategy, PRDs, or business cases to reduce bias and decision risk.

Core Features & Use Cases

  • Systematically inventory key assumptions and map supporting evidence
  • Conduct pre-mortem stress-testing, backcasting, and risk evaluation
  • Calibrate probabilities and validate claims against documented sources
  • Gate decision sign-off with an auditable evidence trail

Quick Start

Describe the key assumptions, map supporting evidence, run a pre-mortem, and finalize a probability-calibrated audit before any major decision.

FAQPage Schema
How do I audit key assumptions before approving a product strategy?

To audit key assumptions, systematically inventory the underlying claims of your product strategy, map supporting evidence to each claim, and run a probability-calibrated pre-mortem to gate sign-off.

What is the best way to map evidence for business case sign-off?

The best way to map evidence for a business case is to validate specific claims against documented sources and calibrate their probabilities, creating an auditable evidence trail for decision governance.

How do I conduct a pre-mortem for a PRD to reduce decision risk?

Conduct a PRD pre-mortem by stress-testing the documented requirements through backcasting and risk evaluation, identifying potential failures before they happen to reduce bias and decision risk.

Can I use probability calibration to validate claims in a risk assessment?

Yes, you can use probability calibration to validate claims within a risk assessment by mapping supporting evidence to key assumptions and quantifying the likelihood of outcomes before final approval.

When do I need structured assumption tracking for governance tasks?

You need structured assumption tracking for governance tasks when evaluating complex business cases, ensuring every key assumption is backed by an auditable evidence trail before signing off on major decisions.
