Seniority & Industry Calibration
Pick the user's sector, adapt the defaults, and don't carry one industry's playbook into another. The gates below are load-bearing, not footnotes.
Same question
“What's the right default here?”
8 answersPick the user's sector, then adapt — don't apply startup advice to enterprise.
Above the fold
Detect the sector first.
Before recommending anything, name the user's industry and adapt to its defaults. The most expensive error is a fluent answer aimed at the wrong sector.
Low reversibility means Type-1 rigor.
In fintech and healthcare, decisions are one-way doors: staged approvals, pre-mortems, and Compliance in the room — gating, not advisory.
A volume metric needs quality floors.
Marketplace liquidity and fintech circuit-breakers exist so a raw-volume North Star can't be gamed against the customer. Ship the floor with the metric.
Per-sector defaults
Each card carries what to emphasize and — where it applies — the regulatory gate that changes how you ship. Pick the user's; don't apply startup advice to enterprise.

Regulatory
For ML credit/risk: model-risk governance — drift, override rates, explainability, valid adverse-action reason codes; ship adverse-action notices on time under ECOA / Reg B.
Capital / liquidity & reserve-adequacy guardrails for balance/credit-holders. A volume NSM is defensible only if quality sits in circuit-breaker (Ring-1) floors derived via a Doshi pre-mortem with Compliance in the room.
Intl: PSD2 / SCA, FCA safeguarding + Consumer Duty, GDPR / data-privacy, local AML.
Patient outcomes · clinical safety
Regulatory
The 21st Century Cures Act CDS carve-out decides clinical-decision-support vs FDA SaMD. Sign BAAs with every subprocessor; PHI minimization + encryption in transit/at rest + access-control & audit logging.
FHIR / HL7 / SMART-on-FHIR interoperability is both a buyer requirement and a moat; distribution via EHR app-markets (Epic App Orchard) can substitute partner trust for your own evidence cycle.
Named clinical safety governance — CMO/CMIO sign-off + change-control so velocity doesn't outrun safety.
Liquidity first · two-sided
Liquidity diagnostic
Diagnose the binding side via fill rate / seller utilization / time-to-match / zero-result-search %. Instrument per-segment liquidity before scoring (Wave 0), then sequence to the constraint (Theory of Constraints).

Responsible-AI pass
Model-metric literacy — precision / recall / F1 / ROC-AUC, basic MLOps — plus bias detection, fairness across segments, explainability (xAI), human-in-loop for high-stakes. Fairness is a guardrail metric, not a launch afterthought.
Calibration trap
In regulated sectors a raw-volume North Star (transactions, originations, GMV) reads as momentum but can be gamed against the customer. It's defensible only when quality lives in circuit-breaker floors — Ring-1 in fintech, the short-side liquidity metric in marketplaces — set before the metric ships, not after an incident.
Base rates
Directional priors, not targets — each is point-in-time. Cite them to calibrate expectations, then verify the current figure before you lean on it.
of shipped features are rarely used → optimize adoption, not output count.
GenAI: ~80% adopt but ~5% see EBIT/P&L impact → judgment is the scarce input.
of large orgs hit target time-to-market at 40+ PMs → scale erodes speed by default.
