California Code, Welfare and Institutions Code - WIC § 10615

California's 58 counties vary greatly in their welfare problems, and therefore they should not be treated alike in the supervision of welfare programs. The Legislature hereby declares its intent that the department examine the extent of state control needed over county operations, with a view toward eliminating excessive rigidity in procedure;  the state should differentiate between those counties which need general direction as opposed to tight supervision.

Within these guidelines, the department shall aid county departments in establishing economic, efficient, and effective methods of operation, including, but not limited to, advising and consulting with county departments with regard to the introduction of electronic computer and data processing systems, personnel utilization, office controls, centralized purchasing, centralized warehousing, writing of specifications, and examination of materials and equipment purchased by county departments.
