Chapter 5 compares the IOM and FAO. It highlights how internal challenges in the absence of serious external threats favour a similar consolidator style in the two IPAs. Both IPAs combine pronounced routines directed towards institutional consolidation with only weak policy advocacy. We show that neither size, budgets, mandate, nor organizational structure can convincingly account both for the IPAs’ pronounced positional orientation and their lack of functional orientation geared towards advocacy. Moreover, the chapter draws attention to the stickiness of administrative styles in showing that such deeply and institutionalized organizational routines tend to display high stability towards endogenous and exogenous change.
