Discovery — Start with business, not features.
Most briefs I receive are feature lists already "translated" from some business pain — and usually mistranslated. Step 1 isn't me nodding along to that brief. I sit down with you (and 1–2 people who actually run operations) across 2–4 sessions, dig back to the business metric you need to move, and only then work up to a technical solution.
The result is a short business audit report (10–15 pages) setting out what the real problem is, what should be solved with software, what shouldn't, and a feasible technical scope for the next 90 days. Plenty of projects stop right here — and I consider that a good outcome, not a failure.
