We'd bet that you have one or the other documents in your
command, depending upon whether you work with the Army or the Navy.
We
doubt whether you have both documents. Each document does have specialized
information which refers to equipment used by that particular branch of the
service.
Now, the next document to be discussed is the MOAT.
MOAT was
developed by Helm and Donnell of the Pacific Missile Test Center, Point
Mugu, in October 1979.
MOAT stands for Mission Operability Assessment
Technique.
As you can see from the title alone, this document addresses
only operability.
Hfteman and Hedge have a much broader range of system
testing functions.
MOAT also differs from the other documents in that this document
presents an evaluation methodology to assess how well an operator can use a
system or subsystem to perform tasks within a mission context.
The
technique provides information on the degree of successful performance. The
usual human engineering design criteria is presented as an all-or-none or
pass-fail situation. MOAT, in general, assesses not the design features of
equipment, but the workload of the operator as a result of the system (which
includes the equipment, of course).
There is another document that also addresses the testing and
evaluation of systems.
HRTES has been developed by U. S. Army Research
Institute for the U. S. Army Operational Test and Evaluation Agency. HRTES
is a Human Resources Test and Evaluation System. It is designed to provide
an adaptable system of procedures to be used in planning and conducting an
operational test and system evaluation.
The procedures will allow you to
evaluate the causes of inadequate performance from the standpoints of
training, human factors engineering, and manpower selection.
We find HRTES to be more general in nature than HFTEMAN or HEDGE.
That is, the procedural steps used in HRTES could be applied to the testing
concepts of HFTEMAN or HEDGE.
So far we have presented the purpose and stages of human factors test
and evaluation.
You have also learned about various documents which will
provide you with the plans, methods, and procedures to enable you to conduct
such tests and evaluations.
Now we would like to introduce you to some
equipment you will be using in your work as a human factors specialist. The
human factors engineering field instrumentation package can be found on
Pages 146-160 of your text supplement. Take a second to flip through this
brochure.
You may have already come into contact with some of the
instruments contained in this kit.
