The organizational process model is one of two new decision-making approaches introduced by Allison in his groundbreaking book (Allison, 1971). According to this model, the national government is not a unitary actor like assumed in the RAM, it is also not comprised of individual decision makers. Instead, it is, as Allison describes, “a constellation of loosely allied organizations on top of which leaders sit” (Allison, 1971: 79). Each organizational unit of the government has special function responsibilities.
