5. Agency Plans Implementation of the HPCC Program takes place within each of the HPCC agencies, where the final decisions are made on the funding, management, and evaluation of program activities. This section organizes HPCC activities by agency [15] to better reflect the operational structure of the funding. The level of information does not reflect individual projects. Since many grants are at the level of $100-300 K, a full breakout of each project in a roughly $1 B program would be extremely difficult to assemble and maintain for this plan. Instead, agencies group together projects that are technically related toward reaching similar goals and objectives. Each grouping constitutes a "program activity", most of which range in size from $0.5 M to $40 M. While this structure does track funds clearly, it does possess several drawbacks. Interagency collaborations are often difficult to recognize and may in fact appear as duplication of effort since similar efforts will be repeated within different agency activities. Also, while the HPCC Program broadly describes its activities under the heading of five major components, actual program activities often span multiple components, thus making some of the actual spending difficult to categorize. In fact, since program activities need not follow strict guidelines of spending within each component, better decisions can be made at lower levels of the program implementation as to the most effective use of the funds to meet Program objectives. Each agency contribution contains three parts: o Brief overview of the agency's perspective on HPCC efforts, o Table summarizing financial data and collaborative ties for its program activities, and o One-page form for each program activity that describes it. The individual program activity form contains some fields that require explanation. The "Budget Account Code" field is an internal label used by some agencies to track HPCC funding. The budget fields provide actual spending, estimated spending (based on Congressional action), and Presidential requests (Pres.) for various fiscal years. The numbers below the HPCC component labels estimate the breakdown of the FY 1995 request into the HPCC components. These numbers are estimates, in that many activities span a variety of elements and categorization of efforts includes subjective judgment. The "Agency Ties" section of the form permits two labels. A "Partner" label indicates that the corresponding agency is a funding and/or research partner in this activity. Note that two different agencies may view partnering differently (e.g., developing a scalable system in ARPA would be HPCS, but its use for Grand Challenges could be inside ASTA in other agencies). A "User" label indicates that the corresponding agency needs the results of this program activity for another activity. The large field in the center of the form gives an overview description of each activity. The remaining fields provide highlights of major accomplishments and milestones planned for future years. While these entries highlight significant objectives and results, they should not be viewed as complete descriptions of any activity. The table at the beginning of each agency's section of the report summarizes the financial data and collaborative ties described above. Again here it is important to recognize that component numbers should be considered as estimates and include subjective judgment. The "Partner/User Agencies" field summarizes the Agency Ties material in each activity; however, due to space limitations, not all agencies may be listed in this field for a given activity.
