Chain of events

A chain of events is a sequence of occurrences where each event serves as a cause for the subsequent one. In the context of ISO 31000 and ISO 22301, it refers to the causal progression of risks that can lead to business disruption. This concept is fundamental for root cause analysis (RCA) and scenario-based risk-adjusted planning. Unlike static risk assessments, a chain of events approach allows enterprises to understand the dynamic nature of risks, enabling them to be proactive rather than reactive. For instance, a data breach (event A) could lead to regulatory fines (event B), customer loss (event C), and ultimately reputational damage (event D). This systemic view is critical for effective Business Continuity Management (BCM)-based on the premise that risks are interconnected, not isolated incidents. The goal is to identify the 'critical nodes' in the chain where intervention can be most effective at preventing the total collapse of a business process.

Application of the chain of events concept in enterprise risk management (ERM) follows three key steps. First, Scenario-Based Identification: using the AcciMap model or Bow-tie analysis to map the causal path of specific threats. Second, Impact-Chain Mapping: quantifying the cascading effects of each event in the chain on key business functions,- particularly focusing on dependencies. For example, a power outage at a manufacturing plant in Taiwan could be mapped through its causal chain to affect the supply-chain-wide production schedule. Third, Control-Point Optimization: designing targeted controls at each node of the chain to break the sequence of events. Companies using this approach have reported a 30% reduction in actualized risk events and a 25% improvement in Recovery Time Objectives (RTO) due to better-prepared response protocols. This methodology aligns with the COSO ERM framework's emphasis on information- and communication-based risk-adjusted decision-making.

Taiwan enterprises typically face three challenges: Organizational Silos, Static Risk Culture, and Data Fragmentation. Silos prevent the holistic view of causal chains across departments, which can be mitigated by establishing cross-functional risk governance committees. Static Risk Culture—where assessments are only updated annually—can be addressed by adopting continuous monitoring-based risk management as per ISO 31000:2018. Data Fragmentation refers to the lack of centralized risk data, which can be solved by investing in GRC (Governance, Risk, and Compliance)-integrated software. The priority should be: 1. Baseline Assessment (Month 1), 2. Control-Point Design (Month 2-3), and 3. Implementation & Monitoring (Month 4 onwards). This structured approach ensures that the investment in BCM yields measurable improvements in organizational resilience.
