“…Unpublished equipment acquisition projects tend to use the minimum number of shots required in order to verify specification requirements in a condensed time period and budget. Even in published literature the number of shots used for each configuration numbered between 3 and 10 shots (Kemnitz et al, 2001;Stone et al, 2014;Yuan & Lee, 1997). The results of the current study indicate that further analysis could be completed on this dataset to better understand the number of shots required for confidence for this particular shooting task.…”

“…A study by Stone et al (2014) compared the effects of two conventional and two bullpup (where the magazine is located behind the trigger and therefore the centre of gravity is closer to the user) weapon systems and found that the bullpup allowed participants to maintain better whole body balance as measured by a force platform, with better balance being associated with an increase in scores. Based on the target effects measures alone, there is unlikely to be any practical capability differences between weapon systems.…”

“…Differences in standard operating procedures may mean a lengthy familiarisation period. Assessments that take into account subjective feelings can add valuable information to assessments (Taverniers & Suss, 2019), however the issue of brand recognition and a desire to emulate elite regiments as well as other nation's armies can sometimes contradict objective measures (Stone et al, 2014).…”

Defence acquisitions use accuracy measures as a discriminating factor in weapon purchases, but assessments are generally completed in static, supported postures at static targets with few differences being seen between configurations. The aim of this study was to investigate whether an assessment requiring repositioning between shots could reveal differences. Participants shot at a static target under four conditions: an unweighted rifle and the addition of a mass fixed at three different positions.Accuracy and timing as well as discomfort measures were captured and compared. Hit percentage, consistency and timing varied over time, and timing increased with the addition of mass in two out of the three conditions. There was an increase in discomfort with the addition of mass further from the participant. The results showed that relying on accuracy and consistency measures alone to make acquisition decisions could have the consequence of purchasing equipment not fit for the human.

Over the past few years, an extensive amount of research has been done in the field of Human Factors. Applications range from the design of day-to-day products like cell phones to the design and development of safety-critical systems like flight displays. The highly critical aviation industry has shown time and again the importance of human-centered approach in developing systems for the safety of those operating it and the passengers. Similarly, other safety-critical industries like law enforcement have been seen to incorporate human factors in the design of weapons and exoskeletons aimed at adapting to humans and making their unit stronger. Many manufacturing firms have begun to see the importance of proper work postures for their employees to avoid musculoskeletal disorders and the financial and regulatory implications of not following proper work ethics that take care of employees’ health. Further, many organizations have started to consider team dynamics in their operations understanding the importance of healthy interaction among the employees and between employees and the management. However, there are a very few references to any studies or organizational practices that draw a connection between human performance and human-centric re-design of work places, with most designs being limited to work desks and activity-based working (ABW) work spaces. This paper focuses on the organizational engineering of storage spaces to enable easy location and retrieval of equipment, thus supporting the time-critical nature of operations at a miscellaneous storage room at the Story County Sheriff’s Office. Experiments were carried out using two familiar scenarios both before and after the redesign of the storage room. A significant improvement in the performance of the operator was observed after the redesign, as could be seen by the reduction in time taken to identify and retrieve equipment and the qualitative survey that was obtained at the end of the experiment. The wasted time was translated to a cost and the newly designed storage design saved a significant amount of money spent on actions that precluded efficient accomplishment of tasks, something that could have been used by the Sheriff’s office to purchase equipment for normal operation of the office. The results suggested such interventions in different sectors that have similar high-priority operations. The results of the study indicates that there is a need for the industry to extend research towards this field that we name “organization engineering”.
