FY2024 NITRD Program Component Areas (PCAs)

The FY2024 PCAs described on this page are those used by NITRD agencies in compiling the PCA budget information for the NITRD and NAIIO Supplement to the President’s FY2024 Budget.


FY2024 Changes to the NITRD PCAs

  • Following a major revision in FY 2023, the NITRD PCAs were reviewed to ensure that the NITRD Program actively addresses evolving IT R&D and policy needs.


IWG-to-PCA Mapping for the FY2024 Supplement

For each annual NITRD Supplement, agencies “map” their NITRD Program activities, coordinated by Interagency Working Groups (IWGs), into Supplement sections and budgets organized by PCAs. The FY2024 IWG to PCA mapping by agencies is available by: Graphic | Text.

* Please note that we understand R&D in AI will intersect with multiple PCAs. For example:

  • R&D on general methods for machine vision would fall under AI, while R&D on robots, even if the robots employ machine vision, would fall under IRAS. Note that R&D on intelligent autonomous systems that exist only in cyberspace, with no physical embodiment, would be reported under AI.
  • R&D on algorithms for computational linguistics would fall under AI, while R&D on the broad problem of human-machine interaction, even if it contains an element of natural language processing, would fall under CHuman.
  • R&D on the cybersecurity challenges unique to AI, such as the ability to exploit flaws in an AI system’s goals would fall under AI, whereas AI supporting cybersecurity research would fall under CSP.
  • R&D on special neuromorphic computing architectures or chips optimized for neural nets would fall under AI, whereas general research in neuromorphic computing would fall under EHCS.
  • R&D that is primarily machine learning would fall under AI, while R&D on the larger data management and analysis ecosystem, even if it contains an element of machine learning, would fall under LSDMA.

Agencies should consider these examples and report an activity under the PCA that is most specific to that activity.
