The Legislature declares that a centralization of business management functions and services of state government is necessary to take advantage of specialized techniques and skills, provide uniform management practices, and to insure a continuing high level of efficiency and economy. A Department of General Services is created to provide centralized services including, but not limited to, planning, acquisition, construction, and maintenance of state buildings and property; purchasing; printing; architectural services; administrative hearings; government claims; and accounting services. The Department of General Services shall develop and enforce policy and procedures and shall institute or cause the institution of those investigations and proceedings as it deems proper

to assure effective operation of all functions performed by the department and to conserve the rights and interests of the state.
