SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Stress-test a plan or design by walking every branch of the decision tree until reaching shared understanding. Use when user wants to challenge a design, stress-test a plan, get grilled, poke holes, or says "grill me".

Core Features & Use Cases

  • Relentless questioning that explores each decision branch to identify gaps and risks
  • Produces a final, numbered list of decisions with rationale for traceability
  • Works across product strategy, design reviews, and planning sessions to validate assumptions

Quick Start

Provide your plan or design and start the grilling session to walk every branch until consensus.

FAQPage Schema
How do I stress-test a plan to identify hidden risks and gaps?

Stress-test a plan by applying relentless questioning to walk every branch of the decision tree until a shared understanding is reached. This probing exposes gaps and risks across product strategy and design reviews.

What is the best way to validate design assumptions during a planning session?

Validate design assumptions through adversarial probing that challenges each decision branch. This method pokes holes in your rationale and produces a traceable, numbered list of final decisions for stakeholder alignment.

Can I use this to challenge a product strategy decision tree before stakeholder review?

Yes, you can challenge a product strategy decision tree before stakeholder review. The grilling session walks every branch to ensure traceable rationale and documented final decisions, satisfying requirements for thorough validation.

How do I document the rationale for design decisions after a risk analysis?

Document rationale for design decisions by capturing the outcomes of the adversarial probing session. The process produces a final, numbered list of decisions with traceable rationale for each walked branch.

When do I need to apply an adversarial probing approach to plan validation?

Apply adversarial probing to plan validation when thorough questioning and evidence are needed to reach consensus. It is ideal for scenario critique, design reviews, and identifying risks across complex decision trees.

Does this approach work for scenario critique or is it limited to product strategy?

This approach works for scenario critique and is not limited to product strategy. It applies broadly to design reviews, plan validation, and any session requiring thorough questioning and traceable rationale across decision branches.
