We define a policy system to be a collection of hardware, software, communication technologies,
persons, procedures, protocols, and standards driven by and for the purpose of advancing a
public organization’s mission in regard to policy analysis, planning, and program evaluation
decisions. While policy systems already exist in practice, we believe that they have not been
identified and studied as a separate, distinguishable area of information systems. They have
components and patterns of use that could benefit governments of all levels in carrying out
policy making. We propose principles for building policy systems, identify their components,
discuss how they address the complexities of policy making, illustrate them with several
examples including our own policy system built for a local government agency, and distinguish
them from related systems such as management information systems, decision support systems,
and collaboratories.
