(c) 区域一级的改革仍在进行中。在各区域，一些区域办事处工作人员指出，需要更多时间在区域一级实施改革。他们介绍说，在获得联合国区域实体对改革的认同方面存在挑战，需要调整管理和方案拟订结构以配合改革。监督厅在 2020年至 2022 年期间进行的评价和其他独立评估虽然没有直接评估区域一级改革的成效，但一致认为区域联合国系统改革不彻底对使联合国区域一级支助与国家一级需求相匹配构成重大挑战。
(c) Still-evolving reforms at the regional level. Across regions, some regional office staff noted that more time was needed for the reforms to be operationalized at the regional level. They described challenges in obtaining reform buy-in from the regional United Nations entities and a need to align management and programming structures to match the reforms. While not directly assessing the effectiveness of the regional level reforms, OIOS evaluations and other independent assessments conducted between 2020 and 2022 have consistently identified the incomplete reform of the regional United Nations system as a significant challenge in aligning United Nations regional-level support to country-level needs.
