adapts the human-made world to the peopleinvolved because it focuses on the human asthe most important component of our
technological systems
the study of human characteristics for the
appropriate design of the living & work
environment

Among the Basic Disciplines are as follows:
a. Psychology
b. Cognitive Science
c. Physiology
d. Biomechanics
e. Applied Physical Anthropometry
f. Industrial Systems Engineering

The Engineering Systems to be developed
must:
--- range from the use of a simple tool by
a consumer to a multi-person, socio-
technical system

The Ergonomics Specialists involved in the systemdesign process:
--- united by a singular perspective on (that)
process
8/6/2019 Ergo Intro
8/18
--- design begins with an understanding of theusers role in overall system performance & that
system exist to serve their users, whether they are
consumers, system operators, production workers,
or maintenance crews
(this user-oriented design philosophy
acknowledges human variability as a designparameter)

Resultant Design:incorporates features that take
advantage of unique human capabilities as
well as build in safeguards to avoid or
reduce the impact of unpredictable human
error
8/6/2019 Ergo Intro
10/18
How to measure Success:--- by improved productivity,
efficiency, & safety
--- acceptance of the resultant system
design
--- improved quality of human life

Hierarchy of Goals in Ergonomics:
1. To generate tolerable working conditions that donot pose known dangers to human life or health.
2. To generate acceptable conditions upon which thepeople involved can voluntarily agree.
3. To generate optimal conditions which are so welladapted to human characteristics, capabilities, &desires, that physical, mental & social well-being is
achieved.

The Fundamental Goal of Ergonomics:--- all human-made tools, devices,
equipment, machines, & environments
should advance, directly or indirectly, the
safety, well-being, & performance of human
beings
8/6/2019 Ergo Intro
13/18
The Utmost Goal of ergonomics:the humanization of work
may be symbolized by the E & E of ease &efficiency, for which all technological systems &
their elements should be designed
(such design requires knowledge of the
characteristics of the people involved, particularly
of their dimensions, their capabilities, & their
limitations)

Two Distinct Aspects of Ergonomics:1. Study, research, & experimentation, in which we
determine specific human traits & characteristics
that we need to know for engineering design.
2. Application & engineering, in which we design
tools, machines, shelter, environments, work
tasks, & job procedures, to fit & accommodate the
humans.

British researchers met in
Cambridge, England to discuss
the name of a new society to
represent their activities
among others, the term
ergonomics was proposed
Ergonomics was formally
accepted as the name of the
new society at its council
meeting
