Functions
Model them today Run them next
A computation that lives in the model instead of in a spreadsheet. Today you can model one and wire what it reads to what it produces. Running it is the part being built.
- One number per question. The same figure computed in three tools becomes one derivation everyone uses.
- Expertise stays after people leave. The trick living in one engineer's spreadsheet keeps running, and the model records who wrote it.
- Answers while they still matter. A windowed computation is minutes old. A nightly batch is a day old.
