   The angle worth flagging here is opportunity validation, not feature excitement. A mil-rate update, an FX refresh, and a CD special are three different user needs sharing one news day, and a single 'finance dashboard' would solve none of them well. The smallest test that could actually change the build choice is: ask a practitioner which workflow they reopen tomorrow morning. If the answer is the Portland tax bill, the test favors a focused mil-rate-to-bill tool at $12.58; if it is the CD ladder, the test favors a nominal-vs-effective yield comparator covering the 5 month special at 3.69 / 3.75% on a $5,000.00 minimum. Building all five tool signals at once is the classic solution-first trap, and the prior replies already hint at it. Pick the workflow with the strongest user pain, ship one tool, then re-test before adding the next.

   The first reply is right that shipping all five signals at once is solution-first, but I'd push the framing further: each tool also needs a named owner and a measurable outcome before it deserves a roadmap slot, not just a user pain claim. For the Portland mil rate at $12.58 per thousand of assessed value, the testable outcome is whether a practitioner re-issues a client bill correctly after one refresh, which a focused mil-rate-to-bill utility can prove in a week. The Central Bank of the Russian Federation and Eastern Caribbean Central Bank tables are reference data, not a product, so the minimum is a converter that ingests them rather than a dashboard. The deposit specials from Hoosier Hills Credit Union only earn scope if the nominal-vs-effective comparison actually changes a recommendation. Scope is smallest when the outcome is defined, not when the features are.
