Chapter 1 – <strong>HFI</strong> within Naval Capability Acquisition<br />
also drive the design of accommodation, layout, services and provision of Escape<br />
and Evacuation facilities. Supportability of the platform or equipment will also<br />
influence the ashore manning requirement at dockside and throughout the<br />
logistics and training support chain.<br />
<strong>Human</strong> <strong>Factors</strong> provides methods for the analysis of the tasks and workload<br />
driving the estimated complement size for a vessel. Frameworks for conducting<br />
top-down functional allocation between human and equipment, and between<br />
different members of the crew have been developed. Some of these frameworks<br />
consider how human role allocation can be varied dynamically as a function of<br />
situation and operational workload, as technological constraints on the definition<br />
and the location of operator and maintainer posts are relaxed.<br />
Contributions to the Basic Manning Requirement must also be cross-referred with<br />
the Safety Case (see JSP 430 ‘Ship Safety <strong>Management</strong>’ [Ref 6]). The Scheme<br />
of Complement and any subsequent changes will affect overall ship safety.<br />
1.3.2 Personnel <strong>HFI</strong> Issues<br />
A clear understanding of the required characteristics of the crew or system users<br />
is fundamental to effective system design. A Project Specific Target Audience<br />
Description (PSTAD) is used to record the required personnel characteristics of<br />
operators and maintainers. The PSTAD is usually developed in the first phase of<br />
procurement and is progressively developed and used at subsequent phases. A<br />
technique known as Early <strong>Human</strong> <strong>Factors</strong> Analysis (EHFA) plays a key role in<br />
determining the need for, and the application of, a PSTAD. It is vital that each<br />
project is very clear about why a PSTAD is required, the role that it will perform<br />
and how it will be used. The development of a valid and authoritative PSTAD<br />
may require significant effort on the part of a large project. However, failure to<br />
properly represent personnel characteristics for use during the design will<br />
increase risks to operational capability, human safety and whole-life costs. HF<br />
issues deriving from the EHFA will also form an input to the Hazard Log as part of<br />
the Safety Case process. Subsequent revision of the PSTAD may be required as<br />
a means of mitigating HF issues.<br />
Target Audience Descriptions are developed as part of equipment programmes.<br />
A PSTAD is a systematic definition of crew physical characteristics, basic<br />
capabilities, skills, rank structure and Branches and relevant organisational and<br />
social factors. It is used to ensure that the development of platform and<br />
equipment matches human requirements. It is very important that this<br />
information is relevant for the future user population rather than simply reflecting<br />
current personnel or practices. The PSTAD should be collated at the platform<br />
level to check consistency and to ensure that personnel characteristics are taken<br />
into account during platform design. It should also consider the effect of real<br />
operational stress and environmental conditions on future human performance.<br />
The range of crew physical characteristics is relevant when addressing internal<br />
layout, escape routes and accommodation, workspace design and equipment<br />
control. The successful design of deck-head height, step size, access and<br />
egress routes and operator and maintenance positions will be determined by the<br />
actual physical size of personnel. The reach envelope of users must be<br />
modelled when assessing the usability of equipment. Accommodation must be<br />
designed to cater for privacy and other requirements for mixed gender crews.<br />
