CHAPTER 1<br />

INTRODUCTION AND CONTEXT<br />

Assistance Evalu<strong>at</strong>ions (CAEs), CAS Completion Report (CASCR) reviews, and<br />

sector and them<strong>at</strong>ic evalu<strong>at</strong>ions to identify m<strong>at</strong>rix issues th<strong>at</strong> had a bearing on the<br />

evalu<strong>at</strong>ion questions. <strong>The</strong> methodology is described in Appendix B.<br />

1.43 <strong>The</strong> portfolio review of project outcomes and trends in the sector and<br />

them<strong>at</strong>ic composition of the portfolio are based on d<strong>at</strong>a from all 4,812 Bank lending<br />

oper<strong>at</strong>ions approved in FY1995-2010, which had a total commitment amount of $441<br />

billion. <strong>The</strong> analysis of cross support and budget support covers about half of th<strong>at</strong><br />

period, comparable d<strong>at</strong>a before FY02 being unavailable. <strong>The</strong> commitment amount<br />

for projects during this l<strong>at</strong>er period, when the fully developed m<strong>at</strong>rix system was in<br />

place, is $213 billion.<br />

1.44 Compar<strong>at</strong>ive analysis. Given the absence of baseline d<strong>at</strong>a, the evalu<strong>at</strong>ion<br />

undertook compar<strong>at</strong>ive analyses of findings from the universe of CASCR reviews to<br />

assess the responsiveness and effectiveness of country programs; time series d<strong>at</strong>a on<br />

budgets, cross support, portfolio outcomes, and them<strong>at</strong>ic composition of the<br />

portfolio; incentives and constraints of regional m<strong>at</strong>rix systems; d<strong>at</strong>a on sector<br />

staffing; d<strong>at</strong>a from manager interviews, the staff survey, and focus groups; and<br />

perceived strengths and weaknesses of the m<strong>at</strong>rix system compared with those of<br />

the pre-1997 system.<br />

LIMITATIONS OF THE EVALUATION<br />

1.45 Attribution of impacts to the m<strong>at</strong>rix is especially problem<strong>at</strong>ic in this case<br />

because of the overlapping effects of other elements of the renewal str<strong>at</strong>egy th<strong>at</strong><br />

have continued to evolve in parallel.<br />

First, most country directors were decentralized to the field (40 of 45 were<br />

decentralized by 2010), which had a significant bearing on the effectiveness of<br />

the m<strong>at</strong>rix.<br />

Second, business processes for managing budget and HR were integr<strong>at</strong>ed<br />

through SAP software in 2001, enabling system<strong>at</strong>ic storage and retrieval of<br />

d<strong>at</strong>a from FY02 but gener<strong>at</strong>ing unanticip<strong>at</strong>ed constraints on oper<strong>at</strong>ional units.<br />

Third, in 2006 two new networks— SDN and FPD—were cre<strong>at</strong>ed by<br />

combining previous networks without anticip<strong>at</strong>ing or assessing the impact of<br />

this organiz<strong>at</strong>ional restructuring on the m<strong>at</strong>rix.<br />

Fourth, QAG was dissolved in 2010, placing gre<strong>at</strong>er burden for quality<br />

assurance on the m<strong>at</strong>rix system.<br />

1.46 Isol<strong>at</strong>ing the effects of the m<strong>at</strong>rix system from these overlapping process<br />

reforms is not feasible. While focusing primarily on m<strong>at</strong>rix issues, the evalu<strong>at</strong>ion has<br />
