different trust funds. A larger share of trust funds finance Bank instruments with weaker quality assurance systems—particularly NLTA—compounding the quality challenge for knowledge and technical services. Finally, the Bank has not been effective in promoting the kind of matrix behavior—cross-sector collaboration and teamwork—that were expected to improve quality. Financial and budgetary incentives play a significant role in discouraging cross support and cross-sector collaboration. The inability to share budgets and task team leadership across organizational units discourages collaboration across sector units. Budget rules create a cross support penalty and budget settlement rules vary across the Regions, creating further uncertainty. Delayed budget settlement for cross support and differential norms for staff costs compared to consultant costs also discourage cross support.
Notes 1 This calculation differs from that in IEG’s Annual Report 2011: Results and Performance of the World Bank Group because it includes the latest evaluations for operations exiting the portfolio in FY10. Inclusion of these operations brings down the share that was moderately satisfactory or better from 76 percent (as reported in the earlier evaluation) to 74 percent for the FY08-10 period, and makes the difference from the FY05-07 period statistically significant. 2 So far, 153 operations have been evaluated. 3 See the Assessment of the Strategic Compact (World Bank 2001c). 4 Findings from sector manager interviews. See Appendix E. 5 Sectors and themes were identified as affiliated with a Sector Board using classifications prepared by OPCS. IEG made one adjustment, considering those sectors and themes identified as affiliated with the Legal Sector Board (to which no projects are mapped) as affiliated with the PSG Sector Board. 6 Although cross support data are incomplete, in FY10 total cross support, including inter-VPU and intra-VPU cross support could be computed for all the networks and four of the Regions. For each of these, that is the networks and the four Regions, total cross support came to 19 percent.
