What evidence should be retained?

Keep the selected answers, date, person completing the quiz and links to supporting documents in the business’s own controlled workspace. Re-run when the scope, ownership, financing or deadline changes. Do not overwrite an earlier score without retaining the reasons for change.

Use an explanation for every zero or one. “Unknown” can become “not relevant” only after explaining why; for a sole owner, partner approval may be resolved, but the owner’s own cash commitment still needs review. Avoid silently removing questions and changing the denominator.
