SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Risk-matrix solves the need to quantify and communicate project risk by producing a qualitative likelihood × impact matrix, a risk register, and recommended responses for identified risks.

Core Features & Use Cases

  • 5×5 (configurable to 3×3) risk grid with anchored likelihood and impact scales.
  • Per-risk scoring with rationale and evidence tracking, plus automation of heat-map visuals via Mermaid.
  • Generates a heat map diagram, risk-by-category chart, and a structured plan for risk responses.

Quick Start

Provide a subject and at least three risks to generate a risk matrix, heat map, and recommended responses.

Frequently Asked Questions about risk-matrix

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a risk matrix and heat map for project risk assessment?▼

Generate a qualitative risk matrix by providing a subject and at least three identified risks. The tool computes a likelihood × impact grid, outputs a risk register, and renders a Mermaid heat map with recommended responses.

Can I configure a 3x3 risk grid instead of a standard 5x5 matrix?▼

Yes, the risk matrix supports a standard 5x5 grid that can be configured down to a 3x3 grid. Both options use anchored likelihood and impact scales to calibrate your risk assessment accurately.

What is the best way to visualize a risk register using a heat map?▼

The best way to visualize a risk register is using automated Mermaid heat-map diagrams. The tool generates heat maps and risk-by-category charts directly from your per-risk scoring and rationale data.

Does the risk matrix support tracking evidence and rationale for each identified risk?▼

Yes, the risk matrix supports evidence and rationale tracking for each identified risk. You can attach evidence or mark assumptions explicitly, ensuring your risk register maintains clear justification per-risk response guidance.

How do I apply risk appetite and time horizon settings to a risk register?▼

Apply configurable risk appetite and time horizon settings to calibrate the risk matrix. These parameters adjust the qualitative likelihood × impact scoring and tailor the generated treatment recommendations accordingly.
