JEV / DECISION ENGINEERING
How to choose Choice, Score, or Noul
Choose by the shape of the answer: category, ordered scale, or probability of a statement.
Choice: one of a defined set
Use it for “which team” or “which model.” Describe what each option covers and include other when none may fit. Overlapping options make the result hard to interpret.
Score: an ordered scale
Use it for low, medium, or high severity. Describe each level in words. Your code decides how a level maps to an action.
Noul: a statement's probability
Use it for “this message expresses urgency.” The answer is a 0–1 probability, not a prose explanation. Split independent judgments into separate questions.
Turn one sentence into three questions
For “marked delivered but missing; needed today,” Choice asks which team handles it first, with shipping, billing, technical, and review options. Noul asks whether it expresses time pressure. Score rates tone against written levels: factual, concerned, or strongly distressed. They share a state but answer different questions.
When a single Choice loses information
A ticket can concern both a missing parcel and duplicate charge. Forcing one first team may hide the other issue. Ask an additional independent question, split the ticket, or send it to review. Changing options calls for re-evaluation.
A selection rule
Use Choice for a discrete category, Score for an ordered rubric, and Noul for one clear statement's probability. If the decision rule cannot be written clearly, define it before asking the model. Branch on answer type because the fields differ.
