To be sure, these inter-agency groups do succeed occasionally. When they do, it is because they have been set up by the chief executive in the government (President or Prime Minister) and are also being regularly monitored by them. This approach is, therefore, limited in scope, as there is only a finite number of such team targets that the chief executive can monitor. It is also not sustainable. A change in the chief executive (head of the government) can change the level of interest and engagement by agencies, and, hence, the degree of eventual success in achieving team targets.
