There has always been a diversity oforganizational forms within the public sector. However, insome countries organizational diversification has increasedsignificantly through the distribution of governmentresponsibilities to so-called "arm's-lengthbodies." This notion reflects their commoncharacteristic of being at arm's length from thecontrol of politicians, outside the hierarchical control oftraditional vertically-integrated line ministries anddepartments. There is some uncertainty concerning the scaleof this movement of staff and budgets towards such agencies.Some commentators maintain that arms-length agencies havealways been found within governments and that some highlypublicized examples of "agencification" haveskewed the debate (Wettenhall 2005). Others argue that thecreation of distinct entities with independent financialmanagement regimes held responsible for discrete areas ofservice delivery is a distinct and growing phenomenon.
