2. Reduce expenditures and promote economy to the fullest extent consistent with the efficient operation of state government;
3. Increase the efficiency of the operations of state government to the fullest extent practicable;
4. Group, coordinate, and consolidate agencies and functions of state government, as nearly as may be, according to major purposes;
5. Reduce the number of agencies by consolidating those having similar functions under a single head, and to abolish such agencies or functions thereof that are not necessary for the efficient conduct of the state government; and
