MIL-STD-46855 Human Engineering Requirements For Military Systems, Equipment, And FacilitiesThis standard establishes and defines the requirements for applying human engineering to the design, development, and acquisition of military systems, equipment, and facilities. These requirements include the work to be accomplished in conducting a human engineering effort integrated with the total system engineering and development effort. These requirements are the basis for including human engineering in proposals; system, equipment, software and associated user interfaces, and facility analysis, design and test; and documentation and reporting.

technical activities that further human engineering efforts, as well as any system reviews that provide an opportunity to gain insight on human performance.

4.6 Program cognizance and coordination. The human engineering program shall be integrated into the total system program and management. The efforts performed to apply the human engineering principles and practices specified herein shall be coordinated with, but shall not duplicate, efforts performed to fulfill other contractual program tasks. The human engineering program shall be coordinated with RAM (reliability, availability, and maintainability), system safety, survivability and vulnerability, facilities engineering, integrated logistic support, and other human factors functions including bio-medical, life support, personnel and training, and shall be integrated into the total system program. The human engineering portion of any analysis,

design or test and evaluation program shall be conducted under the direct cognizance of a qualified human engineering practitioner(s) assigned such responsibility by the contractor.

4.7 Data.

4.7.1 Traceability. Contractor documentation shall provide in a timely manner traceability from initially identifying human engineering requirements during analysis and/or system engineering, through implementing such requirements during design and development, to verifying that these requirements have been met during test and evaluation of approved design, software

and associated user interfaces, and procedures.

4.7.2 Access. All data, such as plans, analyses, design review results, drawings, checklists, design and test notes, and other supporting background documents reflecting human engineering actions and decision rationale, shall be maintained and made available to the procuring activity for meetings, reviews, audits, demonstrations, test and evaluation, and related functions.

4.8 Subcontractors and suppliers. The prime contractor shall be responsible for total system conformance of tasks and products from subcontractors and suppliers to relevant human engineering requirements herein. The prime contractor shall ensure all relevant human engineering requirements, standards, and criteria are flowed to subcontractors and/or suppliers as part of their subcontractor management process.

4.9 Nonduplication. The efforts performed to fulfill the human engineering requirements specified herein shall be coordinated with, but not duplicate, efforts performed pursuant to other contractual requirements. Necessary extensions or transformations of the results of other efforts for use in the human engineering program will not be considered duplication. Instances of duplication or conflict shall be brought to the attention of the Contracting Officer.
