3.INCREMENTAL DECISION PROCESS MODEL The incremental decision process model tells more about the structured sequence of activities undertaken from the discovery of a problem to its solution. It places less emphasis on the political and social factors of the Carnegie Model. In this decision process, a series of small choices combine to produce the major decision. Organisations move through several decision points and may hit barriers along the way. These barriers maybe called decision interrupts. An interrupt may mean an organization has to cycle back through a previous decision and try something new.
