Cause-consequence modelling

Cause-consequence modelling is a risk assessment technique that identifies the causal relationships between risk origins and their subsequent impacts. It uses tools like Event Tree Analysis (ETA) and Fault Tree Analysis (FTA) to map risk trajectories. Aligned with ISO 31000:2018 Clause 6.4.3, it enables organizations to systematically evaluate the progression of risk events. Unlike static risk matrices, this method provides a dynamic view of risk evolution, essential for modern enterprise risk management (ERM)-based decision-making. It differs from simple risk-adjusted-return models by focusing on the causal chain, making it particularly effective for high-impact, low-probability events where traditional-statistical models fail to provide sufficient foresight.

Implementation typically follows three steps: 1) Identifying initiating events (internal failures or external threats); 2) Mapping the causal branches using Event Tree Analysis (ETA) to account for control effectiveness; 3) Evaluating the impact of each terminal scenario. For instance, a Taiwan-based electronics manufacturer might model a semiconductor supply disruption, tracing its effects through production delays, customer penalties, and regulatory fines. This approach aligns with NIST SP 800-30's risk-based approach, allowing for a structured evaluation of risk-adjusted outcomes. Companies using this methodology often see a 25-35% improvement in risk response efficiency due to the clarity of the causal pathways, enabling more precise resource allocation and capital-at-risk-adjusted-return calculations.

Taiwan enterprises typically face three challenges: Data--driven uncertainty, organizational silos, and technical expertise gaps. First, insufficient historical data for causal probabilities can be addressed by using expert elicitation techniques (e.g., Delphi method) and Bayesian networks. Second, the cross-functional nature of causal chains often meets resistance; this is mitigated by establishing a centralized Risk Management Committee. Third, the complexity of the models requires specialized skills, which can be managed through partnerships with professional firms like Winners Consulting Services Co., Ltd. A typical implementation timeline is 90 days, starting with a pilot project on a high-impact risk area before scaling enterprise-wide. Success-oriented companies prioritize the 'impact-adjusted probability'-based approach to ensure the model's relevance to the Board of Directors.
