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.

MIL-STD-46855A

APPENDIX A

such items (e.g., transformers, wheel bearings, amplifiers) has no control over the diverse uses to which they will be applied or knowledge of the human performance requirements implicit in such uses. Accordingly, it is not generally reasonable to invoke MIL-STD-46855 for parts, subassemblies, assemblies or units.

A.3.2.2 Extent of human interface involved. Selection of MIL-STD-46855 for application to a specific contract is sensitive to the extent of human involvement or interface for operation, maintenance, support, control, transport, and/or shelter. Generally, the standard should not be considered for use in contracts for materiel where human involvement or interface is not

anticipated or is obviously insignificant.

A.3.2.3 Nature of stated system performance requirements. If, for a specific request for proposal (RFP) or similar procurement action, MIL-STD-46855 has survived the tests of A.3.2.1 and A.3.2.2, its selection or non-selection should be based on stated system performance requirements. If the RFP, specification, or other requirement document states system performance requirements or goals, such as time and error, for which human performance can reasonably be considered as a determinant or contributor, MIL-STD-46855 should be employed. On the other hand, if such system performance requirements to which human performance contributes are not stipulated, the standard should be considered for use as a guide.

A.3.2.4 Selection review. At this point, use of the standard as a requirement, citation as a guide, or non-selection as being not applicable shall have been tentatively determined. If the procuring activity's human engineering practitioners have not already been involved in this decision-making process, they must be consulted at this point to ensure that the standard is not erroneously involved or waived. Should results of this review disclose that the standard should not be used or should be applied only as a general guide, the process is complete; however, if results of this review conclude that the standard should be invoked, the tailoring process or section A.4 must be pursued.

A.4 TAILORING OF MIL-STD-46855

A.4.1 General. The primary purpose of a human engineering program, and therefore MIL- STD-46855, is to influence the design of the system, equipment, and facility. Every human engineering task must focus on influencing design and test, consistent with the nature of the procurement and the acquisition phase involved.

A.4.2 Tailoring. Unless otherwise specified, contractors shall use the appropriate tailored version of MIL-STD-46855 as a baseline in the preparation of proposal responses and human engineering program planning. This does not preclude the contractor from proposing further tailoring.
