It often does this by creating a Human Factors Integration Plan (HFIP) that sits alongside the system

. The purpose of the HFIP is to define how the Human Factors Engineering activities necessary for the successful delivery of a particular system will be conducted.
It establishes the guiding principles to be followed by the project to implement the best-practice Human Factors methods. As well as the principles involved, the Plan normally describes the organisation, processes and controls necessary over the entire

of the system from the concept phase through to decommissioning.
Domains
HFI undertakes this by conducting a formal process that identifies and reconciles human related issues. These issues are split for convenience into domains. The seven domains defined by the US Army under its
MANPRINT programme are:
Manpower
Human resources (HR) is the set of people who make up the workforce of an organization, business sector, industry, or economy. A narrower concept is human capital, the knowledge and skills which the individuals command. Similar terms include m ...
- The number of military and civilian personnel required and potentially available to operate, maintain, sustain and provide training for systems
Personnel - The cognitive and physical capabilities required to be able to train for, operate, maintain and sustain systems.
Training - The instruction or education, and on-the-job or unit training required to provide personnel their essential job skills, knowledge, values and attributes.
Human Factors Engineering - The integration of human characteristics into system definition, design, development, and evaluation to optimise human-machine performance under operational conditions.
Health Hazard Assessment - Short or long term hazards to health occurring as a result of normal operation of the system.
System safety
The system safety concept calls for a risk management strategy based on identification, analysis of hazards and application of remedial controls using a systems-based approach. This is different from traditional safety strategies which rely on c ...
- Safety risks occurring when the system is functioning in an abnormal manner.
Soldier Survivability - The characteristics of a system that can reduce fratricide, detectability and probability of being attacked and minimize system damage, soldier injury and cognitive and physical fatigue.
The UK Ministry of Defence (MoD) adopted a similar HFI approach to MANPRINT in the early 1990s, but excluded Soldier Survivability. Subsequently the MoD added a seventh 'Social & Organisational' domain. Some industries also include habitability as a separate domain.
HFI Plan
The HFI plan scope defines the relationship between all the activities and the Human Factors domains and provides a
systematic approach to ensure that:
* The human role in the system is defined to optimise human performance in relation to the core
system architecture and ancillary equipment.
* Adequate human-equipment analyses and
trade-off
A trade-off (or tradeoff) is a situational decision that involves diminishing or losing one quality, quantity, or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is where one thing increases, and anot ...
studies are performed, revisiting the assumptions throughout the system life cycle. The process is iterative. As the programme progresses, the HF activities involve greater depth of analysis.
* Biomedical analysis and design support includes the
