It acts as an authoritative resource for tracking the distribution of bureaucratic roles across various government departments. This list is important for ensuring transparency in governance and helps in the administration of seniority, promotions, and postings. Additionally, it aids those studying for the UPSC exam to understand the structure and hierarchy of government services.
