Build the analytical chain so someone else can review it.
The method starts with intended use and ends with documented ownership, limitations, review evidence, and next decisions.
Six stages
Decision framing
Define intended use, decision owner, audience, materiality, timeline, required approvals, and what the work will not be used for.
Data and assumption map
Identify sources, definitions, quality issues, transformations, expert judgments, and assumption ownership.
Model or workflow build
Translate insurance mechanics into transparent calculations, scenario logic, rules, controls, or process states.
Testing and challenge
Use reconciliation, reasonableness checks, sensitivities, stress cases, exception paths, and independent review questions.
Decision package
Present outputs with assumptions, uncertainty, options, tradeoffs, limitations, and the decisions management must make.
Governance and handoff
Document ownership, versioning, review evidence, change control, monitoring, escalation, and any credentialed review required.
