By analyzing statistical highlights of the Office of the Inspector General (OIG) of DHS, this chapter tests the second and fifth case study propositions proposed in Chapter 1. In contrast to the second case study proposition, which says few of the IGs’ investigations result in a recommendation for management improvement, evidence from the DHS OIG Semiannual Reports to Congress and DHS Performance Report fails to support this proposition. Data show that the DHS OIG has not only issued a significant number of recommendations but it has also been receiving great concurrence and acceptance from DHS management. Moreover, data analyzed in this chapter support the fifth case study proposition that says IGs achieve increased savings, indictments, and convictions, and their interventions, findings, and recommendations influence agency management.
