TABLE OF CONTENTS During design and development, the HE inputs made as a result of implementing the results of analyses described in 2.1 through 2.1.3.3, as well as other appropriate HE inputs, should be converted into detailed engineering design features. Design of the equipment should satisfy human-system performance requirements and meet applicable HE design criteria such as, MIL-STD-1472. HE testing of the system or equipment should be considered during design and should include such factors as verifying proper operation, defining need for maintenance, and allocating adequate space for test personnel to perform their tasks. HE provisions in the equipment should be evaluated for adequacy during design reviews. HE practitioners assigned HE responsibilities by the contractor should participate in design reviews and engineering change proposal reviews of all equipment end items that involve the human-system interface.
The contractor should conduct experiments, tests (including dynamic simulation and software prototyping), and studies to resolve HE and life support problems specific to the system. Experiments, tests, and studies should be performed with actual users in the actual user environment (or in a realistic simulation thereof) to validate design goals and system performance. These experiments, tests, and studies should be accomplished as early as possible and reiterated as the design matures, so that their results may be incorporated in equipment design and, if necessary, used to revise initial function allocations. Any significant HE or life support problem deemed resolvable only by a major experiment, test, or study...
