Human Systems Integration
Human Systems Integration (HSI) is the systems engineering process and program management effort that provides integrated and comprehensive analysis, design, and assessment of requirements, concepts, and resources for human factors engineering, manpower, personnel, training, safety and occupational health, force protection and survivability, and habitability (DoDI 5000.95, Glossary).
These HSI domains are interrelated and interdependent and must be among the primary drivers of effective, efficient, affordable, and safe system designs. HSI integrates and facilitates trade-offs among these domains and other systems engineering and design domains but does not replace individual domain activities, responsibilities, or reporting channels (source: DAU).
The goal of HSI is to ensure human performance is optimized to increase total system performance (TSP) and minimize total system ownership costs (TOC). Incorporating HSI early in system design promotes more successful and effective transition of capability to the warfighter.
HSI in DoD Functional Policy and Guidance
The following slides discuss how HSI activity is incorporated into functional policy and guidance.
Engineering Guidance The OUSD(R&E) Engineering of Defense Systems Guidebook and Systems Engineering Guidebook replace the former Defense Acquisition Guidebook (DAG) Chapter 3 and include considerations relating to HSI.
Human Systems Integration (HSI) Guidebook
This guidebook addresses HSI in DoD acquisition. The HSI Guidebook replaces the former DAG Chapter 5, “Manpower Planning and Human Systems Integration.” HSI seeks to consider the human element in all phases of system acquisition and can provide significant benefits including improved use of manpower, reduced training costs, reduced maintenance time, and improved user acceptance. For each of seven DoD HSI domains, the guide provides best practices and explains how HSI can help minimize total ownership cost (TOC) and optimize total system performance (TSP).
Joint HSI Steering Council and Working Group
The Joint HSI Steering Council (JHSISC) chartered the Joint HSI Working Group (JHSIWG) in 2012 as a cross-Service forum for defense and Federal agencies to develop recommendations for DoD HSI planning, policy, and guidance; to oversee and encourage effective and proactive HSI process management; and to support the DoD HSI initiatives.
The JHSIWG conducted an HSI needs analysis resulting in a Capabilities-Based Assessment (CBA) that addresses the following:
- Institutionalize an HSI body of knowledge.
- Standardize HSI best practices across the Services.
- Develop career certification and career paths/billets for HSI workforce supported by a persistent training function.
- Provide and maintain tools, databases, and processes to support HSI analyses early in acquisition.
- Implement a professional, coordinated HSI outreach and marketing function.
The HSI community works to address the CBA and supports S&T capability development areas such as the following:
- Human‐machine designs for mission effectiveness and optimal warfighter interactions
- Inclusion of machine learning and artificial intelligence for advanced teaming
- Sensory, cognitive, and physical workload impacts to Warfighter performance and measurement approaches to assess and improve team effectiveness and survivability for multi‐domain operations
- Assessment, education, and training advancements, to include synthetic environments
