The report mentions that there is no comprehensive staffing strategy to ensure the right mix of civilian personnel in any operation. There are talents within the United Nations system that must be tapped, gaps to be filled through external recruitment and a range of other options that fall in between, such as the use of United Nations Volunteers, subcontracted personnel, commercial services, and nationally-recruited staff. The United Nations has turned to all of these sources of personnel throughout the past decade, but on a case-by-case basis rather than according to a global strategy.
