The studies of the units of the Executive Branch of the State government shall include: program analyses; and careful consideration of the administration, organization, functions, and duties of the units, to identify duplication or overlap. On the basis of the studies, the Secretary shall report to the Governor on changes that the Secretary believes would result in economy or efficiency or otherwise would be in the State’s best interest, including: elimination or reduction of State programs; abolition of positions; changes in procedures; and reorganization or consolidation of units.
