Ranking assigns relative importance to different regulatory components, guiding attention and resources toward the most critical areas. In the Piri framework, incidents, measures, and contextual elements are not equally urgent or impactful. By evaluating their significance and interdependencies, ranking helps organizations focus on the regulations and actions that carry the highest safety and compliance value.

This structured prioritization supports decision-making under uncertainty, ensures efficient allocation of effort, and highlights areas where proactive intervention can prevent failures. Through ranking, regulatory knowledge becomes not just comprehensive, but strategically actionable, enabling organizations to manage risk intelligently and effectively.
