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.
