4.3.18.10. Human Systems Integration
Systems engineering (SE) addresses the three major elements of each system: hardware, software, and human. SE integrates human capability considerations with the other specialty engineering disciplines to achieve total system performance requirements by factoring into the system design the limitations of the human users.
During system design, Systems Engineer should apply Human Systems Integration (HSI) and Human Factors Engineering (HFE) design criteria, principles, and practices described in MIL-STD-1472, Human Engineering and MIL-STD-46855A, Human Engineering Requirements for Military Systems, Equipment and Facilities.
The HSI effort minimizes ownership costs and ensures the system is built to accommodate the human performance characteristics of users who operate, maintain, and support the total system. The total system includes not only the mission equipment but also the users, the training and training devices, and the operational and support infrastructure.
The Program Manager has overall responsibility for integrating the HSI effort into the system program. These responsibilities are described in DAG Chapter 6 Human Systems Integration.
The Systems Engineer supports the Program Manager and is responsible for HSI. The Systems Engineer should work with the manpower, personnel, training, safety, health, habitability, personnel survivability, and HFE stakeholders to develop the HSI effort. The Systems Engineer translates and integrates those human capability considerations, as contained in the capabilities documents, into quantifiable system requirements. Requirements for conducting HSI efforts should be specified for inclusion in the Statement of Work and contract and included in the Systems Engineering Plan (SEP), specifications, the Test and Evaluation Master Plan (TEMP), the Life-Cycle Sustainment Plan (LCSP), and other appropriate program documentation. The SEP Outline requires that HSI be addressed as a mandatory design consideration in Table 4.6-1.
Elements of an effective HFE effort, described in DAG Chapter 6 Human Systems Integration, should:
- Provide a better operational solution to the warfighters
- Lead to the development or improvement of all human interfaces of the system
- Achieve required effectiveness of human performance during system testing, operation, maintenance, support, transport, demilitarization and disposal
- Make for more economical demands upon personnel resources, skills, training, and costs
