The idea of a delineated, sequential policy process framework apparently was much admired, for, as stated above, numerous authors have availed themselves of the framework, either explicitly or implicitly. Charles Jones’s An Introduction to the Study of Public Policy and James Anderson’s references both Lasswell and Jones in his description of the policy stages. In 1983, Brewer and deLeon published their volume, which completely laid out the stages of and retionales for the policy process. All three volumes focused the reader’s attentions on “knowledge of” that is, the working of the policy process as a process-oriented event.
