13. 根据其最近对秘书长提交的各报告的审议，行预咨委会认为，除了上述指标外，仍然存在严重的业绩管理问题需要解决，特别是管理人员对有效和高效地利用其管理的资源的责任问题。这些问题的一些例子包括，(a) 因项目最初执行阶段未采取解决严重内部困难的及时行动及面临领导危机而使“团结”项目的执行出现延迟和费用上涨；(b) 预算执行情况报告继续显示，个别支出类与预算经费相比出现重大差异，行预咨委会认为这并非总是反映出授权活动的变动或业务限制，而且反映出方案规划和预算编制方面的缺陷；(c) 如委员会在其关于飞机舱位标准的报告(见 A/69/787)中所述，没有提供足够的资料用于大会关于资源分配的决策；(d) 秘书处各部厅继续毫无协调地各自为政，造成信息和通信技术结构重复，最近一个例子是审计委员会关于维持和平行动的报告(A/69/5(Vol.II)，第 371至 374 段)所述在未事先进行成本效益分析情况下以 Microsoft Exchange system 邮件服务器取代了维持和平行动中使用的 Lotus Notes 电子邮件系统。
13. Based on its recent consideration of a variety of reports submitted by the Secretary-General, the Advisory Committee is of the view that in addition to the above mentioned indicators, there remain serious managerial performance issues that need to be addressed, in particular on the question of the responsibility of manag ers for the effective and efficient use of resources under their stewardship. Some examples of such issues include: (a) delays and cost escalation in the implementation of the Umoja project because of the lack of timely action in addressing severe internal difficulties and the leadership crisis faced during the initial implementation phase of the project; (b) as budget performance reports continue to show, significant variances under individual categories of expenditure compared with the budgetary provisions, which in the view of the Committee do not always reflect changes in mandated activities or operational constraints but also reflect weaknesses in programme planning and budgeting; (c) lack of availability of adequate information for decision-making by the General Assembly on the allocation of resources, as observed by the Committee in its report on the standards of accommodation for air travel (A/69/787); and (d) Secretariat departments/offices continue to work in silos without coordination, resulting in duplicative information and communications technology (ICT) structures, the most recent example of such being the replacement of the Lotus Notes e-mail system with the mail server Microsoft Exchange system for use in peacekeeping operations, without a prior cost-benefit analysis having been undertaken, as indicated in the report of the Board of Auditors on United Nations peacekeeping operations (A/69/5 (Vol. II), paras. 371-374).
