問題文
A benefits program must decide, from each applicant's household size and income, which benefit tier they qualify for. The rules change occasionally and staff want to maintain them without code. Which tool best fits this eligibility decision?
選択肢
- A sharing rule, because deciding who qualifies for a benefit is a matter of record visibility rather than a calculation.
- A report that lists applicants, as a report can group people by income and thereby assign each of them to a benefit tier on save.
- Business Rules Engine, using expression sets and decision tables to evaluate the inputs and return the qualifying tier, maintained declaratively by staff.
- An Apex trigger that hard-codes the current thresholds, which must be rewritten and redeployed by a developer whenever the rules change, so the tiers stay under version control.
