The new version replaces the previous guide, with a focus modernizing and clarifying the regulations to better align with current industry practices and international standards.

  1. A more user-friendly and comprehensive guide
  2. Emphasis on Quality Risk Management
  3. Clarified Roles and Responsibilities
