SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Premortem Planner helps teams surface potential failures in a plan by imagining future failure scenarios and guiding revisions to strengthen the plan.

Core Features & Use Cases

  • Guided premortem prompts that force consideration of assumptions, integration risks, and user friction.
  • Automatic generation of a revised plan with mitigations and action items for the top risks.
  • Use cases include pre-milestone risk reviews, major feature launches, and cross-team project planning.

Quick Start

Describe a project plan to the AI, ask it to run a premortem, and use the resulting revised plan to guide implementation.

FAQPage Schema
What is a project premortem and how does it help with risk assessment?

A project premortem is a risk assessment technique that imagines future failure scenarios to surface assumptions and integration risks. It helps teams identify potential failure modes in a plan before implementation begins, resulting in a revised plan with targeted mitigations.

How do I conduct a premortem for a major feature launch?

To conduct a premortem for a feature launch, describe your project plan to the AI and ask it to run a premortem. It will generate counterfactual scenarios, surface user friction points, and output a revised plan addressing the top risks.

Can I use premortem planning for cross-team project management?

Yes, premortem planning is highly effective for cross-team project management and integration-heavy initiatives. It guides structured prompts to surface assumptions, evaluate integration risks, and generate a revised plan with action items for the top identified risks.

What's the best way to identify failure modes in early project planning?

The best way to identify failure modes in early planning is running a premortem to generate counterfactual scenarios. This process forces consideration of hidden assumptions, integration risks, and user friction, ultimately producing a revised plan that addresses top risks.

When should I not use a premortem for risk mitigation?

A premortem should not be used as a substitute for active risk mitigation during implementation, as it is an early planning exercise. It is designed for pre-milestone risk reviews and early project planning rather than addressing real-time operational failures.
