Rebuilding Meridian Health Alliance's impact scoring through the impact funnel of eight narrowing stages — why scores fail, harm dimensions, scales and anchors, scenarios, cascades and tails, ranges and bias, aggregation and back-testing; before, a 1-to-5 scale that scored every ransomware scenario 5 and every phishing scenario 3, tied a EUR 180m event with a EUR 40k one and put 190 of 212 entries in one band; after, the Meridian Impact Model v2 scores the 21-day Orion EHR outage as a range from EUR 95m to EUR 260m with a EUR 170m median, counts patient harm per clinical level, and is back-tested against a real incident.

Impact Scoring Scenario Design — The Impact Funnel

An expert-level course that engineers impact scales, scenarios, and scoring practice so cyber risk scores are calibrated, comparable, defensible, and decision-useful - diagnose why scores fail, build a harm taxonomy, anchor logarithmic bands to appetite, construct complex and supply-chain scenarios, trace cascades and design the tail, score in calibrated ranges, aggregate without hiding safety harm, and govern and back-test the model. Four hands-on activities in every lesson, building one capstone model across eight labs.

What you'll learn

Diagnose why an impact scale fails - compression, conflation, control-scoring, anchoring, and incentive - with measured evidence from the register.
Build a harm taxonomy with financial, patient-safety, operational, regulatory, reputational, data, and third-party dimensions that never double-count.
Design a calibrated logarithmic scale with anchor examples per band per dimension, a stated basis and horizon, and bands tied to board appetite.
Construct multi-system, insider, and supply-chain scenarios to a strict grammar and curate a plausibility-gated, versioned library.
