and arrangement of items of equipment, such as modular rack or maintenance ground equipment, which may not be a part of a manned station for operation, but require human access for maintenance.
Systems engineering acq. The program manager should ensure that a systems engineering process is used to translate operational needs and/or requirements into a system solution that includes the
design, manufacturing, test and evaluation, and support processes and products. The systems engineering process should establish a proper balance between performance, risk cost, and schedule, employing a top-down iterative process of requirements analysis, functional analysis and allocation, design synthesis and verification, and system analysis and control. Representative human engineering activities in systems engineering may include the following:
a. Preparing operationally-realistic mission profiles and mission scenarios. b. Preparing functional flow block diagrams for the system.
c. Undertaking a functional analysis of each flow block and definition of operational and support equipment and facilities requirements.
d. Preparing system and subsystem schematic block diagrams.
e. Studying detailed functions, environment and technical design requirements to allocate assignment of tasks to personnel, equipment, software, or some combination thereof.
f. Preparing operations and maintenance timeline analyses to determine system reaction time. g. Preparing and analyzing operational and maintenance task data to determine equipment
quantities, personnel loads, and system down-time for scheduled and unscheduled maintenance.
h. Considering training implications. i. Conducting trade studies.
J. Participating in preparation of specifications for the system.
k. Participating in design reviews, demonstrations, and test/evaluation activities
l. Influencing design of software and hardware user interfaces and applicable processes.
Tailoring acq. The process by which individual requirements (paragraphs or sentences) of the selected specifications, standards, and related documents are evaluated to determine the extent to which they are most available for a specific system and equipment acquisition and the modification of these requirements to ensure that each achieves an optimal balance between operational needs and cost. The tailoring process must, however, conform to provisions of existing regulations governing human factors engineering program and take care not to exclude those requirements which are determined as essential for meeting minimum operational needs.
Task acq. See "Task analysis."
Task analysis acq. A systematic method used to develop a time-oriented description of personnel- equipment/software interactions brought about by an operator, controller or maintainer in accomplishing a unit of work with a system or item of equipment. It shows the sequential and simultaneous manual and intellectual activities of personnel operating, maintaining or controlling equipment, in addition to sequential operation of the equipment. It is a part of system engineering
