Most of the documentation to be discussed will have human
factors and design as focal points, but this is not the only cause of less-

following quote from Howard (1976) should bring home the point. He reported
that 50 to 70 percent of all failures in major weapons and space systems are
human-initiated, placing 'human error ahead of design error, component
unreliability, and lapses in quality control in manufacturing...'
Now you need to be aware of the numerous publications which pertain to
test and evaluation. HFTEMAN, MOAT, and HEDGE are the names of three test
and evaluation documents published by government agencies. You will learn
what each is about in the remainder of this lesson. We will also provide
you information on one other publication: HRTES.
HFTEMAN stands for 'Human Factors Test and Evaluation Manual.' It was
published in October 1976 by the US Navy Pacific Missile Test Center, Point
HFTEMAN comes in three volumes:
Volume I is a data
guide; Volume II provides support data; and Volume III is devoted to methods
and procedures. This document was developed to assist the Navy and Marine
Corps T&E personnel in the evaluation of human factors aspects of weapons
systems, equipment and facilities.
HFTEMAN provides a step-by-step procedure to be followed in evaluating
and/or testing various equipment classes. It provides information on how to
transportability, portability/usability, and erectability.
