Standardized and strengthening authorities of mission support functions. Some reform proposals call for standardizing the roles of the various chiefs, to clarify understanding governmentwide. However, complexities beyond the tensions of the three hats make it impractical to standardize job functions. For example, consider how the chief roles fit into the federal government’s organizational structure -- should they focus on governmentwide priorities via the CXO councils or shared services, or at the department or even bureau level). And given the wide variation in federal departments -- the Department of Education has less than 4,000 employees, while the Defense Department has 2.1 million employees (civilian and military combined) -- does it make sense for CXOs across agencies to have the same job functions?
