(1) Very good.
The first of these stages (subsystem development test and evaluation)
tests individual components and subsystems to determine if they meet the
requirement for which they have been established.
The human factors
engineer can use these tests:
--To determine how well component or subsystem design conforms to good human
--To evaluate provisions for life support, escape, survival, and recovery of
personnel when applicable.
--To identify skills that will be required by the personnel in the system.
(Remember your task analysis lessons?)
--To determine whether equipment being
performance or design specifications.
--To allow training specialists to become familiar with elements of the
system so that they can design better instructional materials for later
So far, what you have been learning concerns development testing or
DT. DT is done in the factory, in the lab, and on the proving ground. Its
purpose is to demonstrate that:
(1) The design and development process is complete.
(2) Design risks have been minimized.
(3) The system meets specifications.
(4) When the system is introduced, it will be useful for the military.
Please remember that DT is not a one-shot affair.
