Software productivity, sustainability, and quality (SPSQ) R&D advances timely and affordable development and sustainment of low-defect, low-vulnerability software; this includes R&D to significantly improve software production processes; productivity, quality, and understanding of the economics of software and its development, sustainability, measurement, assurance, and adaptability; and guarantees of essential requirements such as security, privacy, usability, reliability, and autonomy.



The SPSQ Interagency Working Group (IWG) was formed in 1991 to coordinate Federal SPSQ R&D across 19 participating agencies to achieve orders-of-magnitude reduction in software defects and the time and cost of developing and sustaining software. The IWG gathers information from software experts to ensure that government investment in SPSQ R&D results in the software development technology that is essential to U.S. innovation, emerging technology leadership, security, and prosperity.

Strategic Priorities

  • Advance timely, affordable development and sustainment of low-defect, low-vulnerability software through transformative research in design, verification, operation, utilization, and evaluation of computer software.
  • Enhance critical software quality and productivity to maximize positive economic impact by increasing execution efficiency and trustworthiness and by reducing vulnerability.
  • Modernize and manage research and regulatory infrastructures to improve the safety, security, trustworthiness, and resilience of systems that serve the scientific and multidisciplinary research communities.
  • Develop the future SPSQ workforce by supporting STEM education and training, and supplying the necessary resources such as software libraries, tools, and platforms to support teaching and research.
