Policy analysts work throughout the federal agencies. In addition to small personal staffs, agency heads usually have analytical offices reporting directly to them. These offices have a variety of names that usually include some combination of the words "policy," "planning," "administration," "evaluation," "economic," and "budget.'" 8 For example, at various times, the central analytical office in the Department of Energy has been called the "Office of the Assistant Secretary for Policy and Evaluation" and the "Policy. Planning, and Analysis Office." Often, the heads of agency subdivisions have analytical staffs that provide advice and expertise relevant to their substantive responsibilities. Later in this chapter, we briefly consider policy analysis in the Department of Health and Human Services to illustrate the sorts of functions analysts perform in federal agencies.
