FRONTIER WORKFLOW / HUMAN IN LOOP

The work, step by step.

4 controlled stages
01 / CONTRACT

Define the grain, denominator, and owner before opening a chart.

Metric dictionary, source owner, reporting grain, exclusions, freshness target, and acceptance checks.

Human gate

A business owner approves each definition and any change to a decision-critical metric.

02 / SHAPE

Turn messy intake into a reviewable analysis table.

Typed fields, stable identifiers, join checks, missing-value report, and a frozen analysis extract.

Human gate

Inspect row counts, joins, duplicates, dates, currencies, and personally identifiable data before analysis.

03 / ANALYZE

Ask questions in plain language, then inspect the generated work.

Reproducible formulas or Python, assumptions, diagnostic tables, charts, and sensitivity checks.

Human gate

Review code, filters, sample size, aggregation, outliers, and causal language before accepting a finding.

04 / EXPLAIN

Publish a decision brief with evidence and uncertainty attached.

Executive chart, plain-language finding, source note, confidence boundary, owner, and next decision.

Human gate

The analyst signs off every number and separates observation, inference, and recommendation.
