Keep the reasons when dates change

Roadmaps shift frequently in early teams. Retain user evidence, business constraints, and technical judgments when changing the order.
Otherwise, previously rejected ideas can return months later without their original reasons.

Frame items around hypotheses

Link each item to an outcome to test, two or three pieces of evidence, and an owner. A goal such as safe month end audit archiving gives a feature more context.
Solutions can change while goals and evidence remain traceable.

Retain objections

Rejected options and key objections provide useful references when conditions change.
Slatepath links decisions, research excerpts, and roadmap items to reveal plans needing review when evidence expires or assumptions fail.

Express uncertainty

Public roadmaps show direction and near term focus. Internal roadmaps can mark work as exploration, validation, or delivery to make confidence clear.
