Although the approach to systems development varies widely, the overall approach to human factors engineering in military system development is usually specified by US ML-STD-46855. The approach set out in MlL-STD-46855 emphasizes analysis and reflects the traditional waterfall model of systems development, although there is nothing inherent in the standard to prevent an iterative approach. A review of ten Canadian Forces development projects concluded that the application of human factors engineering, was enhanced by the use of a Human Engineering Project Plan based on MIL-STD-46855. A subsequent survey of approaches used to include user requirements in development projects showed large differences in attitude and practice. The survey identified the need for aids to facilitate the inclusion of users requirements in the Statements of Requirements. Designers also need to know the context in which their system or equipment will be employed. This is particularly true of personal equipment. Few designers of advanced systems have knowledge of operational conditions and constraints. One development the Soldiers Day being undertaken for the Canadian Forces is aimed at providing designers with the context of the roles and tasks that operators perform, as an aid to understanding how equipment will be used.
