How to do HFI
HFI is about mitigating risk, managing
safety, improving performance, and ensuring
the satisfaction and well-being of personnel
to support the delivery of effect. To do this
successfully, it is important to relate human
factors activities to the overall systems
engineering approach used in Capability
acquisition. The diagram in Figure 6
illustrates how key HFI activity stages map
to the Systems Engineering lifecycle and the
Concept, Assessment, Demonstration,
Manufacture, In-Service, Disposal (CADMID)
model. For more information on ‘how to do
HFI’ see the Additional Information and
Resources section.
The HFI process can be divided into
Management and Technical activities, which
should run alongside each other and can be
tailored to suit specific project requirements.
• HFI Management Activities relate to
planning what to do and when – i.e.
ensuring the questions are asked.
• HFI Technical Activities relate to doing
it – i.e. answering the questions.
Together the management and technical
activities of HFI provide a framework for
ensuring that the human element of a
system is considered early in the CADMID
cycle and that the required level of HFI
maturity is reached for Initial and Main
Gates. In order to do this, adequate
resources are needed to ensure that the
necessary HFI activities are budgeted for,
scheduled and managed as part of the
TLCM process. To monitor the progress of
HFI in a project, assurance levels have been
developed to provide a check that critical
activities occur at the appropriate stage in
the project lifecycle.
The remainder of this section discusses the
different management and technical
processes including links to criteria for
technical assurance and links to other
project documentation. Recognising these
links is important because HFI may have
common goals and requirements with other
areas of engineering, e.g. safety; Integrated
Logistics Support (ILS); Availability,
Reliability and Maintainability (ARM).
Aligning activities or sharing information
could reduce effort, e.g. the same task
analysis data could underpin Human
Machine Interface (HMI) design, training
needs analysis and safety assessments.
