T h e new Hewlett-Packard plant a t Stanford Industrial Park is engineered to be the most efficient
yet thoroughly LLlivable" electronic manufacturing facility known. Ultimately to become Hewlett-
Packard's administrative as well as engineering a n d manufacturing headquarters, the Stanford
plant will consist of 6 basic units-over 500,000 square feet of space under roof. While the "new
plant" is under construction the "old" @ facilities (shown below; last unit finished in 1954) will
house Hewlett-Packard's offices and much of manufacturing.
ABOUT HEWLETT- PACKARD
T h e Hewlett-Packard Company was founded in 1939 in Palo Alto,
California. T h e first Hewlett-Packard product was a new kind of instrument-a resistance ca-
pacity audio oscillator. Hewlett-Packard pioneered the resistance capacity circuit which is now an
*`
accepted standard for test oscillator design.
During the past 2 decades, the Company has steadily broadened the instrument line, and now
over 300 basic test instruments are manufactured. Among the more important types are oscilloscopes,
audio oscillators, vacuum tube voltmeters, noise and distortion analyzers, signa1 generators, power
meters, electronic counters and a complete array of waveguide and coaxial instrumentation for micro-
wave work. Approximately 1800 men and women are now regularly employed, and over 150 field
representatives sell and service @ instruments in the United States, Canada and overseas.
Behind every @ instrument is a basic philosophy governing equipment design, manufacture,
sales and service. T h i s philosophy specifies that there shall be built into each @ instrument the great-
est possible usefulness, accuracy, convenience, dependability and dollar value.
Consistently, Hewlett-Packard insures that these standards are met. Every effort is made
to provide the best engineering staff possible, and to pursue the most up-to-date manufacturing
methods.
T h i s means not only modern techniques, but modern machinery. Hewlett-Packard's manu-
facturing departments are equipped with the newest and finest machinery obtainable for the job.
Typical of this equipment is a specialized turret press which punches many sizes of perforations
on instrument chassis with a single setup. Other examples include a heavy duty die casting machine
for fast production of dial drive housings and other stationary parts, a fully-equipped machine shop
for manufacture of precision mechanical parts, and a complete plastic molding department to fabri-
cate special components which are either unobtainable elsewhere, or can be made more quickly and
economically a t @.
I n addition to the different types of commercial machinery, a number of special devices devel-
oped by @ engineers are in daily use. Some of these were developed to meet unusual manufacturing
problems; others were "imagineered" to make some special part better, faster, or at lower cost. T h e y
include such ingeniously simple units as the Lazy Susans, turntables mounting many resistor boards
in a convenient position for assembly. And they include developments which are precision machines
in their own right, such as the Kingman machine which stamps out terminal boards in gross quantities.
Still other unique devices developed by @ to speed or simplify manufacturing include a semi-
automatic reticule scriber reducing reticule scribing time from 45 to 2 minutes and a jumper-twistef
machine twisting up to 4 pre-cut wires a t once. T h e jumper-twister even handles pre-stripped wires.

eons, Nylon gears, etc. terminal boards.
T h e Hewlett-Packard production policy is also somewhat different from that
employed elsewhere. Instruments are manufactured in "runs," and actual fabrication
is preceded by careful planning to insure that a11 parts are available and supplied as
needed to keep the runs progressing smoothly. As many as thirty runs are normally in
progress simultaneously, yet production schedules are kept flexible to permit meeting spe-
cial orders or unusual delivery requirements involving substantial numbers of instruments.
Another unique aspect of the Hewlett-Packard manufacturing process is the use of
the "Product-Centered" approach as opposed to the conventional "Process-Centered''
method. "Product-Centered" means that a group of people and equipment produce a
given group of instruments from prefabricating through assembly, wiring and testing.
T h i s results in intimate familiarity on the part of employees with the finished instru-
ment. I t leads to a more critical self-inspection of work, a greater desire to excel, and
makes possible a "hand-crafted" operation combining the best quality aspects of
the "small company" approach with "big-company" economies to the user.
I n sales and service, Hewlett-Packard makes a particular effort to provide customers with
every assistance that will make the use of @ instruments more efficient and productive. Factory-
trained field engineering representatives provide prompt, on-the-job consultation as well as operat-
ing and repair information. These men are constantly supplied with the latest in technical data and
measurement technique, and are in almost daily contact with the plant at Palo Alto. For one week
of each year, the entire sales organization meets a t Palo Alto for an extensive new-information and
retraining seminar which includes not only theory but actual "field problem" measuring with @ in-
struments and allied equipment. O n many additional occasions, @ representatives return to the plant
for special training or instruction on new instruments and measuring methods.

I n addition to rigid standards of instrument quality, the best engineering and manufacturing
possible, and thorough field engineering service, there is one more aspect of Hewlett-Packard which
deserves mention here.
Through the years, there has come into being a definite attitude on the part of @ people
toward the development, manufacture and service of @ instruments. T h i s attitude is best described
as a genuine and pervasive team spirit, a spirit of cooperation coupled with a common desire to excel.
@ people are proud of the quality and the utility of the instruments they design, make and sell. T h i s
spirit translates itself continuously into better engineering, better manufacturing, and better service.
T h e net result to you is good instruments- the best possible, with broadest applicability and
the lowest price consistent with quality. Dependable instruments that are not only the best dollar
