Guides experimentation engineering for A/B and multivariate tests—hypothesis framing,
primary/secondary/guardrail metrics, design (A/B, A/B/n, MVT), sample size and power,
duration and seasonality, allocation and randomization units, SRM checks, instrumentation,
analysis plans (frequentist and Bayesian workflow level), stopping rules, readouts,
rollout/kill decisions, and experiment registry hygiene (sound statistical practice only).
Use for "A/B test", "A/B testing engineer", "experiment design", "sample size calculator",
"statistical significance", "power analysis", "split test", "experiment readout",
"guardrail metrics", "SRM", "randomization unit", "experiment duration", "multivariate test",
"holdout", or "experiment analysis". Not for analytics stack build (analytics-data-engineer),
marketing copy (cmo-advisor), roadmap-only (cpo-advisor), ML model experiments
(ml-research-engineer-safeguards), or privacy/legal review (compliance-engineer).
Guides hands-on actuarial analyst work for insurance, reinsurance, and pension—reserving and loss
development (IBNR, triangles, chain-ladder diagnostics), pricing and rate indication support
(experience, trend, credibility, basic GLM at spec level), data validation and model I/O review,
reporting packs and workpapers, assumption application under actuary direction, and statutory
tie-outs at analyst depth. Use when the user mentions actuarial analyst, loss development, IBNR,
reserve analysis, rate indication, pricing support, actuarial workpaper, triangle analysis,
credibility, experience study, actuarial reporting, or reserve roll-forward—not actuary sign-off
(actuary), consulting engagements (actuarial-consulting), assumption governance (assumption-setting),
ALM strategy (asset-liability-management), P&C legal depth (property-casualty-insurance), charts only
(data-visualization), or ETL-only pipelines (data-scrubbing).
Guides actuarial consulting engagements—client scoping and SOW design, stakeholder communication
(CFO, risk, boards, regulators at overview level), due diligence and M&A actuarial support,
reserving/pricing/capital review programs, model validation and opinion support, regulatory
interaction prep, and deliverable governance (memos, exhibits, management presentations).
Use when the user mentions actuarial consulting, actuarial engagement, reserve opinion,
due diligence actuarial, model validation engagement, actuarial memo, SOW actuarial,
regulatory actuarial, M&A reserves, or actuarial review—not deep technical modeling execution
(actuary), P&C line education only (property-casualty-insurance), legal advice
(commercial-counsel), or generic management consulting without actuarial lens
(business-consultant).
