In March 2009, QinetiQ conducted an Early Human Factors Analysis (EHFA) on behalf of the UK Department for Transport (DfT) for the implementation of body scanning technology in the airport security screening context. EHFA is a well-established technique, used extensively as part of UK Ministry of Defence (MoD) acquisition. This was the first time EHFA was used in the security domain. The aim of EHFA is to provide an early indication of where key Human Factors (HF) issues and risks associated with body scanners lie so that mitigation strategies can be developed. EHFA is structured around seven Human Factors Domains ranging from Manpower and Training to System Safety and Human Factors Engineering.
