Exhibit IV-1 classifies strategies according to the expected timeframe and relative cost for
this emphasis area. In several cases, the implementation time will depend on such factors as
an agency's willingness to accept a change in policy, legislative needs, or existing
communication infrastructure and/or architecture. The range of costs may also vary for
some of these strategies because of many of the same factors listed previously. Placement in
this exhibit is meant to reflect the most common expected application of the strategy.
Note: P = Proven, T = Tried, and E = Experimental. See further explanation in the Types of Strategies
subsection of Section V.
