The Canary in the Mine
“How,” I asked a consultant, “do you know if someone is trying to offer
a constructive suggestion about computerization or to get in the way?”
“Consider the source,” he said. “Is it coming from a researcher or a
union?”
To some extent the man was right. Some people, unionized or not, may be
no more than twentieth-century version of the Luddites, the English
workers who, during the 1800s, smashed the mechanical looms that were
taking away their livelihoods. Indeed, Dr. Michael Colligan, a NIOSH
psychologist, says, “Opposition to computers is usually kind of veiled
or disguised under more general complaints about eyestrain, headaches,
and physical discomforts often associated with video display terminals
(VDTs).[34]
“But,” Colligan warns, “if you talk with workers awhile, major concerns
begin to surface.” Legitimate concerns. Whether it’s individual workers
or unions, don’t tune out gripers. Listen to people like Joan.
Footnote 34:
The Colligan quotes are from Joel Makower’s useful book _Office
Hazards: How Your Job Can Make You Sick_, published 1981 by Tilden
Press, Washington, D.C.
Joan started out around 1980 as a model employee in a northeastern
office of a major insurance company, whose officials declined to be
interviewed. “I averaged ten hours a week overtime,” she said, “and I
came in when I had pneumonia and a fever of 102.” In a modest way,
helping to unravel the mysteries of the machines, she aided
computerization. Later, however, in a not-so-modest way, she aided
something else: unionization.
By the time I reached her, she had quit her $10,000-a-year job to go
into business with her husband. For more than an hour she poured out her
anger against the terminals and the company that now used them.
“They affected my stomach quite a bit,” Joan said. “Most days I worked,
I would throw up in the ladies room. I didn’t throw up before I started
working on the computer, and I haven’t thrown up since I quit.
“The screens weren’t at all soft on the eyes, even with the glare
screens that snapped over the top. And they were nontiltable.”
She also complained that the screens were too low even for a five footer
like her.
“Could I have some books and put my system on top of them so the screen
will be in the middle of my eyes?” she recalls asking a supervisor. “You
get this constant tension in your back because you’re always hunched
over.”
“No,” she says the supervisor told her in effect, “that’s unacceptable,
totally.”
Why?
“Because,” came the reply, allegedly, “the office won’t look the same.
It won’t be level.”
Joan says management wouldn’t even let her work with the terminal in the
middle of her desk. “They wanted them all on the same side,” she
recalls. “I said, ‘Hey, I don’t work on that side of the desk, sport.’
It was ludicrous, absolutely ludicrous. Even a simple request like that
was too much.”
At least the chair was adjustable “I lowered it so I could get my eyes
as close to the middle of the screen as possible,” she says. “I was so
low that if I opened the middle drawer on my desk I’d bang myself.”
But it was the lights that most irked Joan. They were bright
fluorescents, fine for traditional paperwork but not for the computer
era. Management, pressed by employees, took out many of the tubes; and
yet Joan says some glare-ridden workers still wore sunglasses.
She also complains that the company wouldn’t even offer the operators
eye examinations, an irony, considering that she was processing health
claims.
Again, Joan was a union activist—as a result of her experiences—and some
managers may recoil from the very notion of clerks organizing, and yet
in her litany of complaints about working conditions, there was not one
with which most ergonomics professionals would quarrel. Had management
listened to her on those issues, in fact, it would have been doing
itself a favor. Forcing the workers to strain their necks, backs, and
eyes is hardly the road to higher productivity and profit. It would have
cost several thousand dollars at the very most to change the lighting.
Corporate bureaucracy may or may not have allowed the workers to be
consulted in selection of the terminals, but there is no reason—other
than a misdirected passion for discipline and order—why the company
couldn’t have let Joan change the level of her screen.
Joan’s experiences are a good argument for the Canary-in-the-Mine Theory
of Labor Relations. In the days before electronic gas detectors, coal
miners carried canaries into the pits. The birds’ lungs were more
sensitive than theirs to poisonous fumes. And watching the canaries,
many a miner saved himself and others.
Novelist Kurt Vonnegut, Jr., used the canary-in-the-mine parallel to
describe artists and writers serving as an early-warning system to call
attention to social ills. And workers like Joan, “troublemakers,” are
your canaries. You may not agree with them, and you may aggressively
fight them, but before making up your mind, at least listen to them.
They can anticipate the concerns of less vocal workers scared of losing
their jobs.
“Well,” you ask,“what about my authority as a manager? You knuckle under
to the troublemakers once, they’ll come at you again and again.”
Confident executives, however, will avoid this misplaced machismo. They
will assert their authority more productively, letting workers have a
voice in working conditions but, in return, demanding good, steady
production, which, after all, is the bottom line. When your stockholders
receive dividends, how many will think, What slobs—their VDTs don’t even
line up at the same level!
Ideally, of course, your people won’t have to prop up their machines at
all, because they’ll have helped you choose easily adjustable screens
and other equipment.
“When I help design new computer systems,” says Robert Waters, an
ergonomics specialist with a background in psychology, “I try to find
out who’ll be using them. Then, if possible, I’ll seek out their
opinions.
“If you do that, people won’t feel so threatened. It will be their
equipment, too, not just the company’s. They won’t think, I don’t like
it, it’s bad for me.”
Richard Koffler, editor-publisher of the _Ergonomics Newsletter_, also
recommends giving the worker a voice in equipment selection: “If you can
do it, try it. They’ll tell themselves, ‘I wouldn’t want to look like a
fool because I chose something that wasn’t good.’”
In Washington, D.C., Richard G. Barry, now senior advisor for management
systems at the World Bank, has successfully let employees help pick some
of the computer gear the bank was using. Barry didn’t set out to
experiment. He just decided that giving the workers a strong voice would
be the most logical way.
It happened, among other places, in the offices of the Eastern African
region at the bank’s D.C. headquarters. “We had a few word-processing
machines,” Barry said, “and there were a few word-processing centers
around the bank where we could go if we wanted something done, but
essentially we were starting out from zero.”
The office included two hundred professionals and one hundred
secretaries and other clerical workers, and Barry’s task force
represented them in several ways. One was by job function; lending
officers were there as well as those overseeing the existing projects.
People also came from different parts of the office’s bureaucracy, from
different countries, and, obviously, from different job levels—everyone
from secretaries to division chiefs. Barry didn’t go out of his way to
pamper clerical workers in particular. He simply felt that like any
other bank employees, they should decide what tools they needed to get
the job done.
Secretaries, far from being anticomputer, asked for equipment to reduce
repetitive typing. Managers sought fast word processing, in different
languages, which complicated keyboard requirements. The secretaries
themselves wanted terminals with whose keyboards and screens they’d be
happy. In a microcomputer installation without separate terminals, of
course, there may be less choice.
It took a year for the task force to line up the equipment, and wisely
the actual equipment shopping came last. Instead, the task force focused
on what characteristics it wanted the gear to have. Then it learned what
was available—how products compared to the ideal system within budget.
As a result, the Eastern African region ended up with good, sharp
computer screens, ergonomic furniture from the very start, and a
lighting system fit for computer work. And Barry says the teamwork
helped promote ...
... Good Job Design
A friend of mine, a mid-level manager, was almost salivating over the
economies of computerized word processing.
“You know what I’d do?” he said of an office where he’d worked. “I’d
take out just about all the secretaries and dump them into a central
office. I’d reduce their salaries. They’d be doing less demanding work
and should be paid less.” He wasn’t an ogre. He was reflecting the
thinking of a good many modern managers. It makes sense, doesn’t it,
turning offices into factories, which, indeed, might run twenty-four
hours a day, to make the best use of equipment?
Well, not quite. In fact, not at all. Nor should you try obnoxious
gimmicks like =computerized pacing=.
They’re all threats to good =job design=, which is nothing more than
sensibly deciding what each job includes and how the employee does it.
Consider typing pools—er, centralized word-processing operations. If not
passé, they at least deserve to be; most, anyway. Employees’ salaries
keep rising, even with slowed-down inflation, while the price of
computers is falling. By the end of this decade an average worker’s
salary may exceed $20,000 annually. And yet micros and dedicated word
processors will easily cost less than several thousand dollars. Even
now, for a typical business, Barry says, centralized word processing
simply doesn’t pay; it tears the employee away from his or her boss and
harms the managers’ own work. Executives must vie with other offices of
a company for the word processors’ time. They can’t effortlessly set
their own priorities. And quality is more of a problem, too, because, as
Barry notes, “someone in centralized word processing won’t normally get
hell for not catching an error. I expect my secretary to challenge
anything she’s not certain about. For instance, my secretary will come
in and say, ‘You left such-and-such person off the list of people
receiving the memo.’ Which matters. Often who a memo goes to matters as
much as what’s in the memo.”
And what about the question of knowing which calls to put through to the
boss? Around the time Barry and I talked, he was obsessed with a paper
projecting the World Bank’s office needs for the next twenty-five years.
He didn’t have to tell his secretary of the importance of any call about
the paper. She knew. For she’d been helping him put it together.
“It isn’t a question anymore of the efficient use of the machines,”
Barry says in recommending the traditional secretary over the pool
arrangement. “It’s effective use of the people. It’s like the phone.
Even if people use the phone just twice a day for business, we still
give them their own. We don’t put all the phones in one room, do we?”
You may disagree with Barry and still insist that central word
processing is the most efficient use of both equipment and people; and
maybe your company’s size, economics, or policy will allow nothing else.
But if so, be prepared for more job complaints. Shut off from the
outside world, perhaps in a windowless, poorly ventilated room, the pool
members may feel like Dickensian factory hands. And the claustrophobia
may not just be physical. With no one around but others in drudge jobs
and their immediate supervisors, the workers feel cut off from chances
for advancement. They become obsessed with their immediate surroundings
and may be more apt to notice shortcomings of their equipment. “You look
at studies of typing pools,” says Waters, “and you’ll find they may
actually get in the way of productivity. More workers hate their jobs,
and they’re more likely to dislike their equipment, feel backaches,
other pains.” He says that sick leave, deservedly or not, may increase.
A gray-haired word processor in Manhattan said she disliked even
“clusters,” which were smaller and presumably more pleasant than a giant
typing pool in a back room. She missed the “pretty cozy relationship”
she enjoyed as secretary to one executive.[35]
Footnote 35:
The material on the Manhattan word processor comes from Barbara
Garson’s article in _Mother Jones magazine_, July 1981, p. 32.
“He might send me uptown to return a blouse that didn’t fit his wife. So
he couldn’t very well tell me not to make personal calls. Not that I
stayed on the phone all day. My job was to get his work out, which
included staying late if I had to. He appreciated me. And I expected to
stay with him till he retired.”
Responding to consultants’ recommendations, however, her company one day
offered her three choices. She could work as a mere administrative
assistant, join a word-processing operation, or quit. So she forsook the
familiar typewriter for a Wang. “Ah,” she reflected, “when I think of
those years of correction tape, white-out, retyping!”
Then, continuing her remarks to writer Barbara Garson, she added: “I
want you to take this down: I love my Wang. It’s not the machine that
gave me the shaft.”
What, then, did?
“Straight typing, seven hours a day,” said the word processor. “That’s
the shaft.”
Like Barry, she criticized the quality of work from word-processing
pools—or the lack of it.
“The worst thing,” she said, “is when things come by me with wrong
spelling, wrong information. Sometimes I think I should correct it. I
did at first. But that’s not how they judge me.” It’s by the number of
keystrokes. “So why should I take time to correct their work? And why
should I stay two minutes past lunch if they’re timing me that way?”
Michael Smith, however, makes a good case for careful, sensitive
monitoring.
“Management would be foolish,” he said, “if they didn’t monitor
performance. It’s what you do with the monitoring that counts. If you
use it in a negative way, that hurts performance. It might improve it
for a minute or a half hour while you were watching them, but it might
hurt in the long run.” He recommends, instead, systems that give the
workers themselves “direct, immediate feedback. The faster the better.”
Joan’s old insurance company, shortly after she left in 1982, started a
monitoring system in offices across the country. Some of her
ex-colleagues found it more palatable than a simple keystroke count.
Every six months it adjusted their job levels and salaries. And
production—the number of health claims processed—was just 30 percent in
the formula. Accuracy was another 30. The remainder of the formula
plugged in attendance and supervisors’ observations on job knowledge and
the quality of correspondence. The employees weren’t just at the mercy
of a machine.
“It’s a more equitable system,” said a claims processor whose salary
leaped from $220 to more than $280 a week.
Still, the union claimed that most members weren’t so well disposed to
the new system. That may or may not have been true. Just the same, the
claims processor qualified her own enthusiasm. She wanted faster
feedback from the monitoring. “It would be constructive,” she said, “if
we got it at the end of the day or even weekly.”
The woman, too, hoped to know the exact math behind the salary system:
“I’ve asked my manager a number of times. She said, ‘You wouldn’t
understand it.’ I said, ‘Tell it to me, and I will understand it.‘”
Big questions persisted. Was the insurance company, for instance, really
crediting her extra for writing letters to doctors who haven’t submitted
diagnoses with claims? The company told her that it was—that it still
paid to handle such cases. But she wasn’t so sure. Management, she
claimed, had lied on other matters.
Another worker said the company did not audit enough forms to discourage
slipshod work from high producers.
Even in its first few weeks, with the normal start-up wrinkles, the
system did show some promise. Production was dramatically up. “If I was
a manager and my job was to get the maximum amount of work out of an
employee,” said a claims processor, a union member, “yeah—in that
position I’d use it.” But she worried, justifiably, about her own
future. “Maybe a person has been producing ninety claims a day. How much
more can they push them? They can’t push them past a hundred, so what
else is there for them to do?
“There aren’t many [promotion] opportunities here because supervisors
have been here for years and years,” she said. And she wondered: What
about turnover?
It was winter 1982. A depression or near depression was in full swing.
Would the system have worked well in normal times?
Moreover, how much of a trade-off existed between the claims processors’
productivity and health? NIOSH studied 130 occupations in the 1970s and
found that clerical workers were second highest in illnesses like
coronary heart disease. Also, many of the women in Joan’s former
insurance office had children and blue-collar husbands, and a
Massachusetts study showed that women in such families suffered nearly
double the heart-disease rate of their husbands. And in Joan’s office,
did health insurance claims—for her coworkers’ own ills—cancel out some
of the productivity increases? Moreover, how about the moral issue?
Suppose the monitoring system taxes the employees’ health for short-term
gains; isn’t it almost the same as if the company were belching
carcinogens into the air?
If you’re working in a low-level clerical job without control over your
fate, you’re a good heart-attack candidate, according to R. A. Karasek,
a professor at the Department of Industrial Engineering and Operations
Research at Columbia University.[36] He cites studies showing that
people in “strain occupations” may show twice as much “definite and
suspected myocardial infarction and angina pectoris.”
Footnote 36:
See “Job Decision Latitude, Job Design, and Coronary Heart Disease,”
by R. A. Karasek, who participated in a 1981 Purdue University
conference on job stress. The Karasek findings appeared on pages 48-55
of _Machine Pacing and Occupation Stress_, a book published in 1981 by
Taylor & Francis Limited, London. In Karasek’s words, “Job-design
strategies advocating limited skill usage and decision authority for
the majority of the workforce appear to be associated with a host of
undesirable, unintended consequences ranging from skill
under-utilization (and consequent productivity loss) to increased risk
of coronary heart disease.”
Computerized pacing can increase the stress and health risks. Smith says
it’s rarely if ever the answer in white-collar work, not even mail
sorting—nothing “involving letters, letters, and so on. It doesn’t
improve efficiency because there are a lot of errors.” Pacing isn’t just
monitoring, after all. The work is electronically moving past the worker
as if it’s on a factory conveyer belt. Think of all the lemons Detroit
put on the road in its eagerness for new production records. “With older
workers the error rate isn’t as high,” Smith says of white-collar jobs
paced by machines. “Maybe it has to do with the nervousness of young
people. Older workers always report more job satisfaction. They become
used to the drudgery. It’s a hell of a way to put it, but that’s what
happens.” Not that many older workers love machine pacing, either.
So, in a large, factorylike office, what’s a happy compromise between
lax discipline and mechanized martinets?
You might try =participatory monitoring=.
Hear employees’ suggestions for a fair monitoring system. You needn’t
agree. Just listen. Your people may know of complications you wouldn’t
consider in arriving at your production goals; and you may also get a
better inkling of how long it will take for people and machines to
adjust to each other.
Also, setting goals, keep remembering that tasks vary. Don’t let your
monitoring system penalize people, for instance, who fill out forms more
complicated than other workers‘.
Keep your commitment to quality. Be willing to give employees some time
away from arduous work at the tube. It’s a good way to reduce expensive
errors. And tube breaks might not cost you that much in the end. Can
you, for instance, design your people’s jobs to use them fully while
limiting their time in front of the screens? Maybe you can’t. Perhaps,
with thorough computerization, there aren’t many off-line jobs left. But
try. Maybe, for instance, some data-entry clerks, showing high
motivation, can work part time in low-level telephone sales. The clerks
won’t feel so trapped; and you may discover some top-flight talent.
Ask your employees for their ideas. Who says every tube break absolutely
has to be a _work_ break?
Plan, however, for breaks of one kind or another. NIOSH favors breaks
“of at least fifteen minutes every two hours” for moderately heavy
terminal work and the same breaks every hour for workers in the most
demanding, repetitive tasks. A British labor group even suggests
structuring the workday so that people spend no more than half of it at
the terminal. You might chafe under those restrictions—many American
companies would—but don’t scoff at your own people’s ideas on breaks as
long as they do the work.
Here again, think about the Canary-in-the-Mine Theory of Labor
Relations; do not tune out the complainers: do not misplace machismo.
Terminal Happiness
In the Dark Ages, the pre-VDT days of newspapering, I worked on a
rickety manual typewriter. How I envied Darlene at the desk behind me! I
was a reporter-feature writer, while she was stuck with grinding out TV
listings and obits; but Irving Leibowitz, the editor, had favored her
with a Selectric, and I demanded to know why.
“Well,” Leibo said, “she’s a neater typist.” It mattered. Darlene would
feed her Selectric copy to an =optical character reader=, which helped
convert the typing to newspaper print. “There’s another reason, too,” he
said.
“What?”
“Darlene has a lousier job than you do,” said Leibo, himself a manual
typewriter user, “and just as much typing to do. In fact, more.”
Budgeting for VDTs, you might keep Leibo’s wisdom in mind. He gave out
the best equipment not to his higher-ranking people but to those who
needed it the most.
I thought of Leibo and Darlene when I read of the Grid Compass executive
computer and its original $10,000 price. It might be a splendid machine,
but what a waste of money in many cases. The money instead might go to
buy the right screens and keyboards for subordinates. So often the
difference is just a few hundred dollars, if it exists at all. Don’t
give your employees a say in the selection of equipment and then
restrict their choices through unreasonable penny-pinching. If you can’t
do it the right way immediately, maybe you should wait before you
computerize.
Mind you, no terminal or micro is going to be ergonomically perfect.
“I’d flunk them all,” said Waters, and he started with the DEC VT100
terminal he was using on his job at the time. The display was plain, old
white on black, not the best ergonomically, and it was too dim for many
offices. Fortunately, the lighting in his room was subdued. The
terminal, however, had other shortcomings—for instance, the lack of
simple knobs to adjust the screen’s brightness and contrast. Waters
instead had to control them with a series of keystrokes that he was
always forgetting. His loudest groans, though, were over the numbers pad
to the right of the keyboard. “I count 1-2-3-4-5-6-7-8-9,” Waters said.
“I don’t want anything where I count 7-8-9-4-5-6-1-2-3.” That’s how his
numbers pad was; that’s how my machine’s is; that’s in fact how most
computer pads are.
“Well,” I asked, “isn’t that just like a calculator’s?”
“But,” said Waters, “isn’t it a little confusing to switch back and
forth between that arrangement and the numbers of a telephone? Which are
in the normal numerical order.”[37]
Footnote 37:
Before Bell adopted the standard touch-phone numbers pad, it did a
study showing the superiority of the 1-2-3-4-5-6-7-8-9 arrangement.
The study had strong financial motivations. After all, the more wrong
numbers people dialed, the greater would be the cost to the phone
company, since Bell at the time probably wasn’t charging anyone for
wrong numbers.
You may disagree with Waters, but his message comes through. Even
ergonomics experts can’t always end up in front of the terminal of their
dreams. What you and your people want, however, is a sensible
compromise.
Ideally, rather than simply seeking the biggest discount through the
most massive purchase, you’ll remember that different people need
different terminals. You may in fact save money that way.
An executive who hates to type, for instance, and who doesn’t have to,
won’t need the same keyboard as a data-entry clerk. It still should be a
good board in case he changes his mind, but it needn’t be the most
expensive. With a World Bank-style selection committee, you’ll be more
sensitive to the needs of different offices, different levels of
employee.
Encourage some committee members to spend at least two or three hours
with the equipment you’re planning to buy; they may change their minds
later—but that’s better than no tryout at all.
Testing my Kaypro at dealers, I wrote test letters, composed sample
articles, and tried as closely as I could to duplicate my routine.
Impressed by the low price of the Osborne 1, I gave the little keyboard
every benefit of the doubt. And yet, even after several hours, I simply
could not adjust. “Just a matter of operator retraining” was how one
saleswoman put it after I complained that I kept hitting the return when
I wanted a quote mark. And yet I wasn’t about to gamble $1,800 on a
machine with a keyboard I might forever hate. Ergonomically, I had an
advantage: I was buying just for myself. But a selection committee, made
up of different kinds of prospective users—clerks and executives
alike—is the next best thing to a lone customer shopping with only
himself in mind.
Avoiding the HAL syndrome, your committee should consider, among other
things, the following:
THE SCREEN
For heavy-duty viewing, a terminal or computer should have at least a
nine-inch screen and ideally a twelve incher. I emphasize the words
“heavy-duty.” An executive using a terminal half an hour a week
obviously has needs different from a clerk doing tedious data-entry work
most of the day. Even the executive, however, should have a screen big
enough for unexpectedly long sessions in front of the tube. On the other
hand, suppose a bank teller must view just a few columns of numbers
every now and then; he may never need a screen bigger than a few inches.
Too large a screen, in fact, even in heavy-duty work, may expose one to
glary reflections.
Size preferences can be quirky. I’ll make do for the moment with the
Kaypro’s nine inches, but I wouldn’t mind a bigger screen; another
writer once said he’d like to hook up the same model to a
twenty-one-inch monitor.
The next basic is the color. The two sexes have somewhat different
tastes. Men, says John van Raalte, an RCA scientist, are less sensitive
to colors in the reddish-orange range than are women. That doesn’t mean,
however, that, as a rule, women should automatically have reddish-orange
monitors. For men and women the optimum range of light sensitivity is
usually amber or green. Comfort is high in those ranges, too, at least
for most people.[38]
Footnote 38:
For observations on the merits of various colors, see _Ergonomic
Aspects of Visual Display Terminals_, edited by Etienne Grandjean and
E. Vigliani and published by Taylor & Francis Limited, London, 1982.
Amber screens are popular in Europe, where one study showed a lower
error rate compared to green and other statistics said more users liked
amber.
American computer magazines have breathlessly praised amber. It’s as if
they were fashion publications thrilled by the latest from abroad. But
_some_ U.S. experts question the controls in at least one proamber
study—for example, the number of volunteers, fewer than two dozen. And
Bruce Rupp of IBM points out that it’s harder to produce a steady,
flickerless image with amber than with green. What’s more, an executive
with a company planning to sell amber terminals said screens of that
color burned out faster than did green ones.
Meanwhile, NIOSH says dark characters against a stable white background
are especially promising; and Etienne Grandjean, a leading ergonomist
with many admirers in the labor movement here and in Europe, agrees.
Perhaps there’s a less jarring transition when your eyes move between
the screen and the printed material you may be working with. It sounds
logical enough, and in fact that’s what the Macintosh and many other
computers use. That’s also the display style I saw in the Newspaper
Guild offices in Washington.
“Do you see any flicker?” asked David Eisen, the guild’s research
director, who, in the labor movement, is one of the best-informed people
on VDTs.
I studied the white background.
“The little lines,” I said, “seem to be rolling into each other.”[39]
Footnote 39:
If you don’t want lines on a CRT to seem to be rolling into each other
when you‘re using a bright background, you should worry about
something called a _refresh rate_. That’s the number of times the
picture “repaints” itself on the screen. Etienne Grandjean, the
prominent Swiss expert on VDTs, recommends a rate of at least 80
cycles a second; others say it needn’t be so high. The Xerox 860’s
rate is 70 cycles, according to David Eisen, and that’s better than
average. Still, I noticed the roll, anyway. In a letter to me in
January 1983 Grandjean also recommended a slow phosphor for use with
the white background. That means the images would take longer to
vanish from the screen than they would otherwise—reducing the
perceived flicker.
The machine’s regular operator also saw the roll but said the screen was
comfortable, anyway.
The Guild machine, moreover, a Xerox 860, had the ability to revert to
white letters against a black background, which would have eliminated
the rolling. Would that all screens be as versatile, especially those
used in many tasks or by people with different tastes.
No matter what the task, however, don’t get caught up in terminal
fashion. Stress the basics. Are the characters, for instance, shaped
well? How big? At least .12 inch and preferably .16? Is the =dot matrix=
at least seven by nine? Harry Snyder at Virginia Polytechnic Institute
found that seven-by-nine matrixes produced “significantly fewer errors”
than when subjects worked with those that were five-by-seven. If you
can’t find the information in a machine’s literature, you might use a
magnifying glass to count the number of dots making up the maximum
widths and heights of the characters. Trying the large “N” and several
more letters on my Kay pro, I learned that dot matrix was a mere five by
seven—the bare minimum for light use; for a writer it could be better.
You might also back off twenty inches to see if the dots merge almost
completely into the letters and numbers. Eisen suggests looking for
flaws like “flicker, character blurring at the edges of the screen, and
adequate space between the characters and lines.”[40] Eisen obviously is
looking at VDTs from the viewpoint of the union members. But unionists’
desire for comfort and ease of use often will overlap with employers’
desire for maximum productivity. Woe unto the employer who doesn’t take
advantage of the overlap. In fact, Eisen’s observations here on
keyboards and screens are within the ergonomics mainstream and shouldn’t
be dismissed because of his affiliations.
Footnote 40:

“The two things you must remember,” sums up Waters, “are legibility and
comfort. You may think at first that a five-by-seven matrix is fine. But
after six months your eyes may say, ‘No, No!’—and you may get headaches
and feel you need new glasses. Actually, you simply may need a better
screen. You’ve just got to consider how often, long, and intensely
you’ll be looking at the tube.”
When shopping around, you also should ask, “How many letters and
numbers—how many columns—can fill the screen?”
For word processing you’ll normally want at least 80 columns across, the
standard. Some screens, like that of the Victor 9000 microcomputer, can
display 132, which can be just the ticket for spreadsheet aficionados
with the right software.
You’ll also want to know if you can highlight selected parts of the
screen, for instance, categories of information stashed away in the
computer. You might use =reverse video=—a light background and dark
characters if your normal background is dark—to keep track of columns
showing names and addresses. Not interested in phone numbers? Then those
columns for the moment would be the normal light-dark combination. In
word processing, reverse video could show you the blocks of texts that
you planned to move or erase or underline.
Two other amenities—more than amenities, in fact—would be easily
reachable and adjustable controls for changing brightness and contrast.
The Kaypro lacks a contrast control, much to my chagrin. At least I can
adjust brightness—a “must” normally and one still “mustier” for people
using antiglare filters, which reduce light from the screen.
Keep thinking what you or others will most use the computer for. Color
graphics? Fine. But your multicolor monitor won’t display characters as
sharply as a black-and-white or =monochrome= screen would, and the
screens might lose their crispness faster and add to the eyestrain of
heavy word processing. One-color screens, then, would be best for
typical writers and secretaries. On the other hand, if you’re an
executive or clerk working with many figures alongside each other, the
color monitor might help you and your eyes keep the numbers apart.
Might. Some people may object to color except for graphics.
Two kinds of color monitors are common. The =composite= monitor is
technically more like a home TV than the =RGB= or “red/green/blue” kind.
It’s cheaper. But colors blur into each other more than with the latter
type.
Whatever monitor you buy, keep the screen clean.
And don’t be surprised if, in a year or so, the characters start looking
a little fuzzy. Harry Snyder, a leading expert on the ergonomics of
monitors, says the half-life of a tube in heavy use is normally about a
year. Don’t stint on replacements and jack up your people’s error rates.
THE KEYBOARD
Remember Raquel toiling at a keyboard attached to her computer?
Maybe she’s happy. She may have a well-built back, a graceful, flexible
neck, wrists that don’t quit, or simply a body compatible with her
machine and furniture. But I still question the attached board for most
people.
Unless Raquel spent many hours on the machine before buying it, she
might not have known if she’d be comfortable.
The more time you spend at a keyboard, the more likely you‘ll end up
with the right one. Test keyboards thoroughly. If you‘re buying several
dozen, you or a staffer might spend a good three or four hours with the
machine you’re about to purchase. A difference of just 10 percent or so
in the number of keystrokes per hour per operator could mean thousands
of dollars annually to your business.
Even if you’re buying a machine just for your own use, you should still
put in a good half hour checking out the keyboard. That’s true with any
computer. But the odds are stacked against you if you buy one with an
attached board. In Norway, in effect, computer keyboards by law must be
detachable, and in Germany official standards require them in most cases
(an exception exists for, among other things, limited-use portables with
built-in screens and keyboards).[41] Increasingly, union people here are
raising the issue—and quite justifiably, considering the feeling of most
ergonomics experts. Detachable keyboards, in fact, were one of the
issues over which a California union struck the local Blue Cross-Blue
Shield organization.
Footnote 41:
The German requirement for detachable keyboards appears in paragraph
4.3.1 of Standard ZH1/618 of “Safety Regulations for Display
Workplaces in the Office Sector,” as released by the Trade Cooperative
Association, Central Office for Accident Prevention and Industrial
Medicine.
“Well,” you ask, “what about keyboards on infrequently used machines?”
You might, however, end up using the keyboard more often than you
expected. So play it safe. Make all boards detachable. It won’t cost
that much more. Also, keep the cords at least four feet long. And
unstrap the keyboards from the VDTs in the first place—which sounds
insultingly elementary, except that I’ve heard of an absentminded
company that, until a labor dispute, had forgotten to do so.
Also, don’t let the best keyboards become status symbols in reverse. A
well-meaning but wrong executive on the West Coast brags he does _not_
have a terminal with even a good board. He’s a fast typist but thinks he
could spend his time better giving dictation. “An executive typing,” he
says, “is like hiring a brain surgeon to give out pills for a sore
throat. If you’re paying him $50,000 a year, why should he do a $20,000
job two hours a day?”
Most executives would agree. But this is rapidly changing; more and more
executives are tapping out spreadsheets and eventually will do their own
word processing. They may bat out rough drafts on computers or word
processors, then have secretaries whip the documents into shape
electronically without having to retype all of them.
Besides, you can learn typing at any age. And you needn’t be an
excellent typist for computers to help you; indeed, with mistakes easier
to zap, the worst typists will profit the most. Take a Maryland
architect-consultant named Jess McIlvain. Before he got an IBM PC, he
just couldn’t write or type at length—worrying that the result “looked
like the cat had walked over it.” Two years later he was cranking out
reports several hundred pages long.[42]
Footnote 42:
The McIlvain example comes from _PC Magazine_, May 29, 1984.
The new breed of managers, of course, may feel at home on the keyboard
from day one. Some colleges even now require students to buy computers,
many of which they’ll almost certainly use for word processing. What’s
more, as you’ll read in Chapter 11, executive keyboards can ease the
transition in the future to telecommuting.
So don’t impose your own work habits on a junior executive with fast
fingers. Why shouldn’t he or she have a deluxe keyboard if it helps him
serve your company better? And you yourself shouldn’t feel awkward with
at least a good board for quick memos.
Mysteriously, IBM forsook the Selectric tradition in designing the
keyboard of its original Personal Computer, where the left shift key,
oddly, isn’t immediately next to the “Z.” The deviation left some
computer magazine editors flabbergasted. Companies even started making
keyboards for the PC—at several hundred dollars apiece—that retained the
traditional layout.
“They’re not like normal keys,” my consultant friend Michael Canyes
complained of the ones on the PC itself. “They click on and off like
switches.
“A good key,” he said, “gets stiffer as you press down. But the IBM’s
are either up or down.”
Some cynics have a theory. Maybe IBM didn’t want the PC to steal too
many customers away from the Displaywriter costing several thousand
dollars more. Yes, keyboards are a matter of taste, and unlike Michael,
I can stomach the switchlike =tactile feedback=. But the shift location
is inexcusable. IBM in effect admitted its goof; the IBM AT, a more
powerful cousin of the IBM PC and XT, appeared with a much-improved
keyboard.
At least the original IBM PC’s keyboard surpassed that of the tiny,
chiclet keys on the first PC_Jrs._ Reluctantly—after sales were
flagging—IBM replaced the chiclet-style boards with more conventional
ones.
Pity us “users.” Even terminals intended for mainframes and minis can be
turkeys. I actually favor my Kaypro board over a terminal—from Digital
Equipment Corporation—which Waters once was using with a big mini at
work. Blame the old-style programmers who didn’t grow up with word
processing. “Most can’t type like a secretary,” says Canyes, “so the
manufacturers often skimp on the touch.”
And isn’t it strange? You can buy an electric typewriter with adjustable
touch for $200 but not get it in a computer costing fifty times as much.
I asked David Eisen why he hadn’t raised the touch issue. Wouldn’t bad
keyboard matches hurt productivity?
“That’s more the companies’ problem,” he said. “We’re more worried about
health.” He can’t recall a flood of complaints from Guild members about
keyboards with the wrong touch.
Union people, however, have talked about another change, flat keyboards,
now popular in Europe. The tops of U.S. boards commonly slant at fifteen
degrees. And Waters tells of an experiment where, given the ability to
change the angle, most participants settled for the fifteen-degree one.
A caveat, however, is in order. Maybe the people ultimately would have
done better with a flat board and plenty of practice on it. Perhaps you
want an adjustable board. But for me, anyway, it won’t matter as much as
touch.
Another issue is the QWERTY keyboard versus the more modern layouts.
“QWERTY” means the first six letters found on the boards of nearly all
American computers and typewriters. It’s a nineteenth-century legacy—a
bad one. The early typewriters couldn’t keep up with the nimbler
typists, so the machines’ designers thwarted the humans. QWERTY isn’t
alphabetical, it doesn’t bring together commonly used letters like “t,”
“h,” and “e,” nor does it use finger muscles properly. The Dvorak board
and other latecomers should work better. In practice, though, they might
confuse typists, so here’s a solution. Let us old-fashioned people
QWERTY away. But think about buying machines you can switch over for
people trained on more efficient layouts. A program like Smartkey—which
electronically changes the keyboard—might be the answer if you also
relabel keys on machines used by Dvorak typists. The Apple II(c) even
has a switch on the top of the machine to go from QWERTY to Dvorak. Some
say the Dvorak improvement is dramatic. Waters isn’t so sure. He says
some studies have indicated that the Dvorak board offers as little as a
5 percent increase in speed and little reduction of errors. “So in the
end,” says Waters, “most people in the industry have decided not to
tinker with the key arrangement.”
No matter how they’re arranged, your keys shouldn’t be shiny; a matte
surface is good. So are neutral colors rather than black and white,
except, says Eisen, for function keys. My Kaypro sins. Its keys, like
those on Digital Equipment’s VT100, are a gleaming black, which,
however, doesn’t matter that much to me, since I can control my lighting
and normally don’t look down at the board when I’m typing. (Some other
Kaypros have black matte keys.)
Function keys—the ones that let the operator delete a word or add a
paragraph with a single touch—should ideally be a different color from
the main keyboard’s. The same for number pads. The function keys if
possible should have labels indicating their purpose. If not, a chart
near the function keys might show, for instance, that “P1” “Deletes
Word.”
Some people, however, say that function keys really slow you down, that
they make you take your fingers off the main keyboard. I basically
agree. The same would hold true for the use of Macintosh-style mice.

Good Furniture
“People will adapt very nicely to automation,” an IBM official once
said, “if their arms are broken, and we’re in the twisting stage now.”
That was in 1975. Since then, however, in a literal way, some computer
makers have been gentler with people’s arms—and wrists and backs.
A variety of good computer furniture exists now, some in walnut, some in
formica. With all the trimmings, you can vary:
