WORKING ACROSS ORGANIZATIONAL BOUNDARIES: THE USE OF CROSS SUPPORT<br />

Methodology for IEG Analysis<br />

DATA AND DATA SOURCES<br />

42. IEG’s analysis used d<strong>at</strong>a extracted from the Business Warehouse’s resource<br />

management budget accounting module as of December 2010. It covers the period<br />

FY02 to FY10: Pre-SAP d<strong>at</strong>a was unavailable and FY01 d<strong>at</strong>a has been excluded<br />

because it reported on the basis of different budget rules.<br />

43. R<strong>at</strong>her than calcul<strong>at</strong>ing cross support as a percentage of total staff time, IEG<br />

elected to restrict its analysis to technical staff graded GF and above.<br />

44. Although part of the motiv<strong>at</strong>ion for the analysis lies in the potential for<br />

comparisons across Regions and discussions of time trends, a strong note of caution<br />

should be issued in view of the following:<br />

Cross support sold, whether in staff weeks or as a percentage of total staff time,<br />

is a function of the size of the selling unit. Hence, reorganiz<strong>at</strong>ions and mergers of<br />

units have an impact on the amount of cross support sold.<br />

Intra-VPU cross support budget settlement rules vary from one Region to the<br />

other; so do unit sizes and organiz<strong>at</strong>ional structures. Though the reviewers<br />

<strong>at</strong>tempted to control for those aspects (e.g. by adopting consistent c<strong>at</strong>egoriz<strong>at</strong>ion<br />

of Regions’ various units), disparities of a structural n<strong>at</strong>ure are likely to remain.<br />

Key Findings<br />

INTER-VPU CROSS SUPPORT<br />

45. In FY10, inter-VPU cross support sold was about 5 percent of GF+ staff time<br />

overall: 3.3 percent from Regions and 12.5 percent from network anchors. As Table<br />

H.2. shows, the biggest seller (in terms of percentage time sold) among Regions was<br />

the Middle East and North Africa, with 3.8 percent; Europe and Central Asia, with<br />

2.9 percent had the lowest staff time sold outside the VPU. Among network VPUs,<br />

the Human Development Network (HDN), with 15.1 percent, was the biggest<br />

provider of inter-VPU cross-support followed by 12.7 percent from the Sustainable<br />

Development Network (SDN) for inter-VPU cross support.<br />

46. Anchors mainly sold cross support to Regions. Out of the 12.5 percent of staff<br />

time sold by network anchors, 11.4 percent was sold to Regions: HDN 3 sold 14<br />

percent of time to the Regions; the lowest sales to Regions (i.e. 8.3 percent of staff<br />

3 Although there is in practice more than one anchor unit within each network VPU, we will hereafter<br />

refer to the network anchor as a whole instead of each Sector Board’s anchor unit within their<br />

respective network VPUs.<br />
