2-7 Why Integrate Human Factors?

HF Perspectives in Defense Acquisition Policies. The importance of effective integration of HF in the development process is further supported by requirements for Defense acquisitions:

  • “HSI [Human Systems Integration] implementation during capability acquisition will have a positive, and probably large, return on investment in terms of:
    • Reduced probability of adverse safety and health outcomes
    • Reduced probability of acquisition program failure
    • Improved equipment effectiveness
    • Reduced overall costs” (Australian Department of Defence)
  • The U.S. Department of Defense requires a “comprehensive HSI program using an appropriate strategy to ensure HSI-related and human performance requirements are achieved. The program will consist of:

    1. Risk management, engineering, analysis, and human-centered design
    2. The human engineering design approach for the operator and maintainer
    3. Task analyses
    4. Analysis of human error
    5. Use of human modelling and simulation
    6. Usability and other user testing to support and inform human and machine interface analysis under operational conditions
    7. HSI risk management maintained through: (a) Design. (b) Development. (c) Testing. (d) Production. (e) Fielding. (f) Sustainment
    8. A training strategy for leaders, operators, maintainers, and support personnel” (DODI 5000.95 Human Systems Integration in Defense Acquisition)
