In 2017/2018, the Secretary-General laid out vision to shift the United Nations management paradigm through decentralization of decision-making authority; simplification of policies and processes; and, strengthening of a performance-driven, accountable and transparent culture. As part of that, the Department for Operational Support was established on 1 January 2019. DOS plays a key part in supporting a United Nations that is more agile, effective, transparent, accountable, efficient, pragmatic and decentralized to better support its organizational and operational activities.
