Cabinet makers don’t do sprints because everybody knows what a cabinet is, there isn’t any need to aggressively iterate on the design.
The software equivalent to buying cabinets is buying existing software. You don’t employ a bunch of engineers to install cabinets.
If you went into workshop with a bunch of mechanical engineers and asked “I need you to reinvent the idea of holding plates,” that might take some sprints. It would be a silly thing to do, but it would make the analogy fit.
