1 Suggested Requirements for a Definition 1). The definition shall distinguish HSI from other, related fields. 2). The definition shall identify the relationship between HSI and Systems Engineering. 3). The definition shall identify the relationship between HSI and Management. 4). The definition shall explicitly specify the domains of HSI practice. 5). The definition shall apply internationally. 6). The definition shall apply to military, public and commercial sectors. 7). The definition should include designing for coordination/cooperation between people and machines. 8). The definition shall be clear in terms of scope, intent and coverage. INCOSE White Paper, Definition of Human Systems Integration v4, Steven Deal HSI Definitions and Domains HSI Domains HSI Domains Definitions (.pdf document opens in a new window) HSI Domain Activity (.html interactive document opens in a new window) HSI Definition Human systems integration is primarily a technical and managerial concept, with specific emphasis on methods and technologies that can be utilized to apply the HSI concept to systems integration. As a concept, the top-level societal objectives of HSI are to significantly and positively influence the complex relationships among: 1. People as designers, customers, users, and repairers of technology 2. Government and industrial organizations that regulate, acquire, design, manufacture, and/or operate technology 3. Methods and processes for design, production, and operation of systems and equipment 1

2 Human Systems Integration Model HSI Double Integration Process Ten HSI Principles Top level understanding and advocacy. Human centered design ( Systems include humans). Source selection policy. Organizational integration of all human factors domains. Documentation integration of HSI into acquisition process. Quantification of human parameters. Application of HSI Technology. Test & evaluation integrated with HSI. Highly qualified HSI practitioners. Broad HSI education and training program. 2

3 NPS Definition Human Systems Integration (HSI) acknowledges that the human is a critical component in any complex system. It is an interdisciplinary approach that makes explicit the underlying tradeoffs across the HSI domains, facilitating optimization of total system performance. A Conceptual Model of HSI System Acquisition Lifecycle Environment As constrained or enabled by: Yields/Assessed/ Domain Advocacy for Development Cost Delivery Schedule Design Risk Evaluated by: Usability M + P + T + HFE (This advocacy can take various forms, e.g., standards, formulas, models, regulations, expertise.) (The process is influenced by these contextual variables.) Safety Statistics Mishap Rates Survivability Habitability Maintainability Reliability Operating and Lifecycle Costs Total System Performance (Inputs) (Enablers and Constraints) (Intermediary or First Order Outcomes) (Final Outcome/ Product) Miller & Shattuck, 2008 International Council on Systems Engineering (INCOSE) Human Systems Integration Working Group (HSIWG) Human Systems Integration (HSI) is the interdisciplinary technical and management processes for integrating human considerations within and across all system elements; an essential enabler to systems engineering practice.

4 U.S. Army MANPRINT is a comprehensive management and technical program that focuses on the integration of human considerations (i.e., capabilities and limitations) into the system acquisition process: concept development, test and evaluation, documentation, design, development, fielding, post-fielding, operation and modernization of systems. It was initiated in recognition of the fact that the human is a key component of the total system. If the human cannot perform efficiently, the entire system will function suboptimally. MANPRINT Handbook, Pg 1. U.S. Navy HSI is that aspect of systems engineering and PM s efforts that addresses the extent to which humans will be required to operate, maintain, and support the resultant design, including analysis to reduce manpower, improve human performance, and minimize personnel risk. HSI is the integrated analysis, design, and assessment over the lifecycle of a system and associated support infrastructure in the domains of manpower, personnel, training (MPT), human factors engineering, personnel survivability, habitability, safety, and occupational health.

5 US Air Force HSI is a grouping of seven distinct functional areas: Manpower, Personnel, Training, Human Factors, Safety, Health Hazards, and Survivability. Together, these elements define how the human impacts system and mission effectiveness. Elements are interdependent and must be examined together. Human in HSI includes operators, maintainers, supporters, and trainers (Active, Reserve, Civil Service, and Contractors) who perform required tasks in the intended operational environment. There are two levels of integration that must occur for HSI to be effective inter-element (element versus element) and element versus design. Interelement integration can be viewed as optimizing the mix of manpower, personnel, training, human factors, safety, health hazards, and survivability considerations. The HSI elements currently exist as independent disciplines in the Air Force. Each discipline is compartmentalized, practiced by separate agencies at various times and, for the most part, independent of each other. Under this "stovepipe" approach, each element must find its own way into the acquisition process by whatever methods are available. HSI brings these areas together so that interdependencies can be highlighted and trades made from a common base of knowledge. NASA Human Systems Integration is an umbrella term for several areas of "human factors" research that include human performance, technology design, and humancomputer interaction. The study of Human Systems Integration at NASA Ames Research Center focuses on the need for safe, efficient and cost-effective operations, maintenance and training, both in space, in flight and on the ground. Canadian Defence Department Human-Systems Integration (HSI) is aimed at incorporating Human Factors issues into the development and acquisition of systems and equipment to improve military performance. It also impacts the training systems and methods required and the criteria used to select and assign personnel to the jobs created by the new or modified system. The scope of HSI includes: Manpower and Personnel requirements, Training, Safety and Health, Operator/maintainer equipment interface, including: human and system capabilities, task analysis, information overload, the crewstation and working environment Performance and design evaluation, including: workload assessment, prediction of human performance, human error reduction, test and evaluation.
