A grand design attempt at publicadministration reform can be thought of as any centrallydesigned, multiple agency reform program or process designedto modernize or improve the performance of administrativestructures at the center of Government, usually with a focuson addressing persistent underlying inefficiencies.International practice shows that reforming selected centralinstitutions (especially those that hold the purse strings)is a different matter altogether from addressing performanceissues in large ministries with a service delivery mandate.Therefore, it is of critical importance to ‘unpack’ theseparticular reforms and uncover the persistent issues thatarise in countries attempting to pursue such reforms. Thefour grand design cases highlighted here were selected fortheir comparability in terms of size and economy, and asexamples of reforms from different regions. The casespresented here are Brazil, Nigeria, Russia and Tanzania.Each of these cases has specific characteristics, based on aunique country or reform context, but they share thefeatures of a broad, across-the-board reform approach (inthree of the four cases with a clear sub-national dimensionthat is distinct from the national one). This note focuseson the three critical design aspects of such reforms: a)reform coherence, b) effective anchorage and, c) blendingtechnocratic solutions with substantive service delivery improvements.
