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.

4.4 Risk management. Risk management procedures shall be planned and implemented for the entire lifecycle of the system. Human performance and human engineering design criteria issues that involve potential technical, cost, or schedule risks shall be identified, analyzed, and prioritized early to coordinate with program management and establish requirements for eliminating or reducing the associated risks to acceptable levels. Such provisions shall be implemented and monitored during the human engineering program. Human engineering shall participate in defining criteria for system acceptance to achieve operational suitability. Risk management shall:

a. Identify potential cost, schedule, design, safety, and performance risks that result from design aspects of human system integration;

b. Quantify such risks and their impacts on cost, schedule, and performance;

c. Evaluate and define sensitivity of risks interrelated with human engineering design;

d. Identify alternative solutions to human engineering problems and define the associated risks of each alternative;

e. Document the identified risks, their impact, and the mitigation action(s) taken;

f. Take actions to avoid, minimize, control, or accept each human engineering risk; and g. Ensure that human performance risks are included in the program's risk management

process.

4.5 Reviews.

4.5.1 System reviews. Human engineering program and technical status shall be reviewed at program, technical, design, and system reviews, which include, but are not limited to:

a. Concept and requirements definition b. Analysis of alternatives

c. System requirements review d. Technical readiness review e. Preliminary design review

f. Critical design review g. System design reviews h. System safety reviews

i. Engineering change proposal reviews

J. Post-implementation reviews

4.5.2 Subsystem and other reviews. Human engineering program and technical status shall be reviewed in subsystem reviews, including, where applicable, software and associated user interfaces specification, test readiness, and functional reviews (e.g., support, training, systems engineering, test, and manufacturing). Human engineering shall also participate in other
