Management system owners
Fermilab is organized into divisions, sections and offices that group similar talents and functions together around common objectives. There is, however, a common set of business functions that cut across the laboratory. To provide insight, consistency and simplified reporting to the Department of Energy, Fermilab recognizes 16 management systems that group common functional responsibilities across the lab. These management systems may be supported by a few individuals or an entire team. Each management system is led by a management system owner who is accountable for developing policies and procedures for common, labwide implementation of the management system.
