low-chance, high-impact event

A low-chance, high-impact event, often called a "black swan" event, is a risk that falls into the quadrant of a risk matrix characterized by extremely low probability but severe consequences. The ISO 31000:2018 standard provides a framework for identifying, analyzing, and evaluating such risks. Unlike routine operational risks, their unpredictability and destructive potential make them unmanageable through traditional controls alone. Therefore, within a Business Continuity Management System (BCMS) compliant with ISO 22301, organizations must use scenario analysis to envision these events and conduct a Business Impact Analysis (BIA) to understand their potential effects on critical processes. The focus is not on preventing the event, but on building organizational resilience to respond, control damage, and rapidly recover core operations when one occurs.

Application follows the business continuity management (BCM) lifecycle. Step 1: Risk Assessment & Impact Analysis. Following the ISO 31000 framework, identify potential events (e.g., pandemics, major supply chain disruptions) via scenario analysis. Then, conduct a Business Impact Analysis (BIA) per ISO 22317:2021 guidance to determine Recovery Time Objectives (RTOs) for critical functions. Step 2: Strategy & Plan Development. Based on BIA results, formulate response strategies like setting up a disaster recovery site, diversifying suppliers, or securing business interruption insurance, and document them in a Business Continuity Plan (BCP). Step 3: Exercising & Maintenance. Conduct regular tabletop or full-scale simulation exercises, guided by ISO 22398, to validate the plan's effectiveness. A leading Taiwanese semiconductor foundry, after experiencing a major earthquake, improved its BCP through regular drills, which enabled it to reduce disruption by over 50% following the 2011 Japan earthquake's supply chain impact.

Taiwanese enterprises face three main challenges. First, cognitive bias and an 'it won't happen to us' mentality, leading management to underestimate these risks and underinvest in preparedness. Second, resource and cost constraints, especially for SMEs, make the high cost of redundant systems or insurance premiums a significant barrier. Third, supply chain fragility; Taiwan's complex, globalized supply chains lack transparency, making them vulnerable to a single point of failure that can trigger a cascading crisis. To overcome these, companies should elevate this to a board-level strategic issue, using scenario analysis to raise executive awareness. They can adopt resource-sharing models or phased implementations to manage costs. Finally, implementing a supply chain risk assessment program, requiring key suppliers to demonstrate their own business continuity capabilities, is crucial for enhancing resilience.
