Triangulation

Triangulation is a qualitative research strategy originating from the social sciences. Its core concept involves using three or more different data sources, methodologies, investigators, or theoretical perspectives to study the same phenomenon. This enhances the credibility and validity of the findings. In AI risk management, it plays a crucial role in validation and verification. For instance, the NIST AI Risk Management Framework (RMF) emphasizes comprehensive Testing, Evaluation, Validation, and Verification (TEVV) for AI systems, and triangulation is a powerful technique to achieve this. It's not simple data aggregation but a process of cross-verification to confirm conclusions or uncover deeper issues by analyzing convergences and divergences in the results, which is vital for assessing complex risks like algorithmic bias and model robustness.

In enterprise AI risk management, triangulation can be applied systematically. Step 1: Define the risk assessment scope, such as evaluating the fairness of an AI credit-scoring model. Step 2: Select multiple validation sources. This could include (a) Data Triangulation: analyzing customer data from different time periods or regions; (b) Methodological Triangulation: combining quantitative bias tests with qualitative methods like interviews with loan officers; and (c) Investigator Triangulation: having internal data science, compliance, and external ethics teams conduct independent reviews. Step 3: Synthesize and cross-validate findings. If statistical tests show no bias but interviews reveal perceived unfairness, this discrepancy signals a potential risk requiring deeper investigation. This approach can increase audit pass rates and reduce model-related customer complaints.

Taiwanese enterprises face three key challenges. First, data silos and inconsistent quality hinder effective data triangulation. The solution is to establish a robust data governance framework, championed by senior leadership, to promote data sharing and standardization (e.g., based on ISO 8000). Second, a lack of multidisciplinary talent, as risk teams often lack qualitative research skills. Forming cross-functional teams with members from IT, legal, and business units, supplemented by targeted training, can bridge this gap. Third, resource constraints, especially for SMEs. A pragmatic approach is to start with internal resources, such as using investigator triangulation among different departments, and prioritize the method for the highest-impact risks before engaging external experts.
