Find the right tool for this decision.

Start with the question you need to answer

“Which option fits my priorities?” Use the decision matrix. First remove options that fail a non-negotiable requirement. Then compare the feasible alternatives using the same criteria.

“What could make this plan fail?” Use the premortem. Focus on plausible mechanisms and early warnings, then assign a specific action to the risks that matter.

“What did I expect, and what did I learn?” Use the journal. Capture your reasoning before the outcome and add a separate review later.

You can use them together

Compare two approaches, challenge the preferred one, then record why you chose it. Download your outputs so you can bring them to a discussion or review them later. There is no automatic transfer of your entries between tools.

Designed for personal thinking and team conversations

Use the tools for a purchase, a project approach, a career choice or a working arrangement. A shared screen can support a team conversation, but the site does not provide collaborative accounts or cloud synchronization.

If people disagree, capture the disagreement rather than averaging it away. A difference in scores may reveal a difference in evidence, priorities or constraints.
