Struggling for Recognition (1940s–1960s) [C]: Marked by formal statutory mandates (such as the Factories Act, 1948) and the emergence of trade unionism. The personnel function struggled to establish itself beyond basic clerical and legalistic administration. Achieving Sophistication (1970s–1980s) [B]: The function moved toward professionalization, marked by the merger of IIPM and NILM to form the National Institute of Personnel Management (NIPM) in 1980. The focus shifted toward regulatory conformity, operational efficiency, and structured HRD systems. Promising (1990s Onward) [A]: Post-economic liberalization (LPG era), HR transitioned into a strategic business partner focused on human values, global competitiveness, talent retention, and organizational transformation. Thus, the correct chronological sequence is D → C →B → A.
