Decision Memo Template for Upstream PD Teams

A useful decision memo is not a report dump. It should answer four things in order: what decision matters now, what is most likely true, what evidence supports or weakens that view, and what the next experiment set should be.

For upstream PD teams, this kind of memo reduces drift between data review, management updates, and experimental planning. It also makes failure modes explicit instead of burying them in presentation fragments.

The memo becomes most valuable when it is tied to a real branch logic: what would make the team change the plan, not just what the team already suspects.
