Build or buy scorecard
One page. Every activity gets its own line: purchasing, stock, unit record, factory acceptance test, commissioning, service tickets and reporting, in that order. Columns show how many project variants touch it, who changes it, whether a ready product covers it, and a final choice of buy, build or both. A footer lists the data export and source access terms that every vendor must confirm in writing before you sign, which keeps the exit route open.
