5. Set the Goals and Objectives for the DDA program

10. The DDA program needs
to be assessed
 To test assumptions
 To manage expenditures
 To insure that the program is
meeting the goals
 To insure that work processes are
meeting program needs

17. A project team was formed
to develop metrics and
implement data gathering
processes that would make
the assessment data easily
available
