Models and Their Role in GAO

This paper was originally developed to serve as a discussion paper for a special Program Planning Committee session on "Models and Their Role in GAO." At the session, the Program Analysis Division was requested to revise the document and issue it to all GAO professional staff to familiarize them with the GAO previous involvement with models, to present some of the lessons learned from past GAO modeling efforts, and to identify some modeling areas which require further work.
