01 · The request
“We have an in-house method and want to put it on our website so prospective clients can try it themselves, and so it shows our expertise.”
02 · Our approach
- Organise the decision criteria into pure-function formulas, kept separate from the interface.
- Results calculate as you type, with a plain-language reading.
- The same formulas support a multilingual interface.
