Execute Consulting Analysis

Create the transparent transformation between approved evidence and a derived result. Preserve the central lead's bounded test; do not decide the overall answer.

Use this skill only when the result materially depends on a calculation, sizing, score, benchmark transformation, experiment, diagnostic, business case, model, scenario, multi-source reconciliation, or sensitivity—not to repeat a reported number.

Run the analysis loop

1. Restate the test. Preserve the hypothesis, decision use, method boundary, and support/refute/inconclusive conditions. State what the analysis can and cannot establish.
2. Lock material inputs. Record decisive source/extract, version, fields, population, period, units, denominators, and transformations. Reuse the evidence skill's canonical minimum_access_request when a decision-changing input is inaccessible; do not reproduce a competing field specification.
3. Choose a readable method. Explain the formula, model, comparison, score, experiment, or solver; expose assumptions and decision-changing rules.
4. Run relevant checks. Reconcile totals, units, denominators, missingness, duplicates, joins, ranges, signs, formulas, and benchmark comparability. Test calibration, leakage, bias, confounding, or model validity when applicable.
5. Test sensitivity and rivals. Vary inputs/assumptions capable of changing the decision and test whether a simpler rival fits.
6. Rerun only affected logic when a qualified input changes; show the exact before/after input and result delta.
7. Return, do not adjudicate. State result, method, checks, sensitivity, limits, suggested hypothesis status, and conclusion boundary.
