The 2003 Exhibit 300 required more than 300 individual data inputs to complete. A significant enhancement was the addition of several data fields related to the Reference Models as well as the use of the Reference Models being incorporated in the business case scoring by OMB examiners. See also:

An Exhibit 300 consists of two parts, each of which is designed to collect information that will assist agency management and OMB during budget review.

Part I of an Exhibit 300 is the Capital Asset Plan and Business Case (done for all assets, not just IT systems).

Part II is Additional Business Case Criteria for Information Technology.

The Exhibit 300 process is being automated for the FY06 submission. Instead of the spreadsheet files of past years, an agency’s exhibit-300 submittal to OMB is now required to be in XML format. What is needed is a means to integrate the source information in a single repository and to generate the appropriate Exhibit 300 data.

Exhibit 53 is a table (shown below) that represents a summary of an agencies IT investment portfolio in total and by individual investments grouped by type (IT Investments by Mission Area, IT Infrastructure and Office Automation, Enterprise Architecture and Planning, and Grants Management). Each of the line items for major investments in an Exhibit 53 is a roll up of particular line items and elements from the Exhibit 300s. The information in the Exhibit 53 allows the agency and OMB to review and evaluate each agencies IT spending and to compare IT spending across the federal government.
