The decision log template product teams actually use
A free, lightweight decision log template you can copy in two minutes, plus the eight fields that matter and how to keep it from going stale.
Every team keeps a backlog. Almost none keep a decision log. So three months later, someone asks “wait, why did we drop the onboarding redesign?” and the answer lives in a Slack thread nobody can find, a meeting nobody recorded, and the memory of one person who has since left.
A decision log fixes that. It is the single place where you write down what your team decided, when, and why. Not a wiki. Not a 40-page spec. A short, durable record that anyone can scan.
Here is the exact template we recommend, the fields that earn their place, and the one habit that decides whether it survives past week two.
What a decision log is (and is not)
A decision log is a running list of the meaningful calls your team makes: what was decided, the reasoning behind it, and who owns it. Each entry is a few sentences, not an essay.
It is not a meeting-notes dump, a project tracker, or your documentation. Those answer “what are we doing.” A decision log answers a different and more expensive question: “why did we do it this way, and what did we rule out?” That is the context that disappears first and hurts most when it is gone.
The template
Copy this. Eight columns, one row per decision.
| Field | What goes here |
|---|---|
| Decision | The call, in one sentence. “We will ship onboarding v2 without the video step.” |
| Date | When it was made. |
| Owner | The one person accountable for it. Not a team, a person. |
| Status | Proposed, Decided, or Reversed. |
| Context | The 2 to 3 sentences of why. What problem, what constraint. |
| Alternatives | What you considered and rejected, and the reason. |
| Scope | What this touches: a feature, a team, the whole product. |
| Links | The thread, doc, or design where it happened. |
That is the whole thing. The two fields people skip, Alternatives and Context, are the two that make the log worth keeping. A decision without its rejected options is just an instruction. With them, it is a record your future team can actually reason about.
A filled-in example
Decision: Use email magic links as the default sign-in, not passwords. Date: 2026-05-14 · Owner: Priya · Status: Decided Context: Most of our users are on shared design machines and forget passwords constantly. Support tickets for resets were our #2 category. Alternatives: Passwords with a reset flow (rejected: the reset flow was the problem). Social-only login (rejected: locks out users without those accounts). Scope: Auth, all users. Links: #product-auth thread, the auth RFC doc.
Notice you can understand the entire decision in fifteen seconds, including what you are not doing and why. That is the bar.
Where to keep it
Any of these works. Pick the one your team already lives in:
- A spreadsheet (Google Sheets, Excel). Fastest to start, sortable, ugly but effective.
- A Notion or Confluence database. Nicer filtering, one row per decision, can link to source docs.
- A flat doc. Fine for small teams. Newest entry at the top.
The tool matters far less than the next section.
The part everyone gets wrong
Most decision logs die for one reason: someone has to remember to update them, after the fact, by hand. The decision happens in a Slack thread or a design review, everyone moves on, and the log entry never gets written. Two weeks of that and the log is already lying to you.
The fix is to capture the decision at the moment it is made, in the tool where it is made, not in a separate ritual later. When the call lands in Slack, log it from Slack. When it is settled on a Figma file, log it from the file. If logging a decision takes more than ten seconds, it will not happen.
This is precisely the gap Dcyde closes: you capture a decision from Slack or Figma with one command, the eight fields above travel with it, and everything lands in one searchable feed your whole team can read. The log stays current because keeping it current is no longer a separate chore.
But you do not need a tool to start. You need the template and the habit. Copy the table above, log your next three real decisions today, and see how it feels to find them again next month.
Start with one entry
The hardest entry is the first. Open your log, take the most recent real decision your team made this week, and fill in all eight fields. If you cannot remember the alternatives you weighed, that is exactly the information you are about to stop losing.
