Human Factors Integration (HFI) is the process adopted by a number of key industries (notably defence and hazardous industries like oil & gas) in Europe to integrate

into the systems engineering process. Although each industry has a slightly different domain, the underlying approach is the same.

Overview

In essence HFI tries to reconcile the top down nature of system engineering with the iterative nature of a user centred design approach (e.g.

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 ...

- 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 - 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
