22. 行预咨委会回顾，联索支助办任务的执行采用了多种服务方式，诸如小规模部署工作人员、使用第三方商业供应商(外包给咨询人、个体订约人和商业订约人)和由非索特派团部队在行动区提供服务(见 A/73/762，第 7 段和 A/72/789/Add.6，第 33-37 段)。在审计委员会 2017 年应行预咨委会要求进行的采购审计方面，行预咨委会同意审计委员会的意见，即联索支助办需要加强对采购和合同管理的内部控制和责任追究(A/72/789/Add.6，第 5 和 6 段)。因此，行预咨委会建议核准设立 2019/20 年度 24 个拟议员额中的 22 个员额。行预咨委会相信，2018 年进行的全面审查和人员配置审查所提出的加强工作人员能力的建议，将消除已查明的差距和风险，以便联索支助办向其客户提供反应迅速和有效的外勤支助，并加强资源和财务管理的问责制和效率(见上文第 9 和 10 段)。考虑到联索支助办的现有能力和拟议能力，行预咨委会建议不按拟议在助理秘书长办公室设立行政干事(P-3)员额以及在预算和财务科设立财务和预算干事(P-4)员额。任何有关的业务费用应作相应调整。
22. The Advisory Committee recalls that UNSOS mandate implementation has been achieved through the utilization of a mix of service modalities, such as a light staffing footprint, the use of third-party commercial vendors (outsourcing to consultants, individual contractors and commercial contractors) and the provision of in-theatre services by AMISOM troops (see A/73/762, para. 7 and A/72/789/Add.6, paras. 33-37). In the context of a procurement audit conducted by the Board of Auditors upon the request of the Committee in 2017, the Committee shared the view of the Board that UNSOS needed to strengthen internal controls and enforce accountability over procurement and contract management (A/72/789/Add.6, paras. 5 and 6). The Advisory Committee therefore recommends approval of the establishment of 22 of the proposed 24 posts for the 2019/20 period. The Committee trusts that the proposed strengthening of the staff capacity arising from the comprehensive review and the staffing review conducted during 2018 will address the gaps and risks identified so that UNSOS will provide responsive and effective field support to its clients and strengthen its accountability and efficiency in the management of resources and finances (see paras. 9 and 10 above). Taking into account the existing and proposed capacity of UNSOS, the Committee recommends against the proposed establishment of the posts of Administrative Officer (P-3) in the Office of the Assistant Secretary-General and Finance and Budget Officer (P-4) in the Budget and Finance Section. Any related operational costs should be adjusted accordingly.
