A decision log documents not just what was decided but why — the options considered and the reasoning behind the choice — so the context survives after people forget or move on. The recommended columns are Date, Decision, Owner/Decider, Options considered, Reasoning (why), Status, and Links/evidence. A decision log differs from meeting minutes: minutes record a single meeting chronologically, while a decision log collects only decisions and their reasoning across meetings. Argumentree can turn a discussion or meeting transcript into a structured decision log automatically, extracting the decision, the options, and the pro/con reasoning, and keeping an audit trail of how the group reached it.
A simple, free decision log you can copy or download in seconds — and capture not just what your team decided, but why.
A decision log is a running record of the significant decisions a team makes. Each entry captures what was decided, who decided it, the options that were considered, and the reasoning behind the choice. Unlike a task list or a set of meeting minutes, a decision log is built to answer one question later: why did we decide this?

Keeping a decision log by hand works — until the reasoning column starts getting skipped. Argumentree can turn a discussion or a meeting transcript into a structured decision log automatically: it extracts the decision, the options considered, and the pro/con reasoning behind the choice into a hierarchical argument map, and keeps a full audit trail of how the group got there. You start from the same columns as this template, but the reasoning is captured for you instead of typed in after the fact.
A decision log is a running record of the significant decisions a team or organization makes — each entry capturing what was decided, who decided it, the options considered, and the reasoning behind the choice. Unlike a task list, it documents why a decision was made, so the context survives after people forget or move on.
At minimum: the date, a one-sentence statement of the decision, the owner or decider, the options that were considered, the reasoning (the arguments and trade-offs), the status (e.g. proposed, decided, revisit-by), and links to the evidence or discussion. The reasoning and options columns are what separate a useful decision log from a bare list of outcomes.
Meeting minutes record what happened in a specific meeting — attendees, discussion, and action items, in chronological order. A decision log is decision-centric and cross-meeting: it collects only the decisions themselves, with their reasoning and status, so you can look up why something was decided without re-reading every meeting's notes.
Yes. Copy it as Markdown or CSV, or download the CSV, and use it in any tool — a spreadsheet, a wiki, a doc — with no sign-up. Argumentree offers it as a free lead magnet; automating the log with AI is the optional paid step.
