While Army policy requires training developers to consider embedded training (ET) first and foremost among training options, effective implementation of this policy has been hampered by the lack of specific procedures for determining what to embed early in prime system development. This paper describes specific procedures that assist a user in making those early ET decisions. Although task information has traditionally been the primary criterion used in selecting media for training, it is thought to be less important in deciding when to use ET than are the following factors: policy; system availability for training; the technical feasibility of ET implementation; the effects of ET on system reliability, availability, and maintainability; the impact of ET on system manpower and personnel requirements; the need for training-specific interface hardware; safety; and cost-effectiveness. These factors are incorporated in three sets of flowcharts, designed to be used in different stages of the acquisition process.
