The development of hot new technologies and the breakneck
growth of high-tech firms mean little, economically speaking,
if these new capabilities are not built into the productive
process. A great many pundits fear this is the case today.
U.S. research and development labs routinely discover pharmaceuticals
to treat cancers and devise biological processes to produce
such compounds cheaply and safely. Entrepreneurs and investment
bankers grow rich and millions of workers find employment
in firms hawking miracle fibers, hyper-fast digital switches,
or products that generate power from the sun, the wind, or
the tides. But despite this cornucopia of hustle and invention,
income gains over the past quarter century appear slim when
compared to the pace established by the U.S. economy across
the age of modern economic growth, a record running back to
the early nineteenth century.
There is a good deal of debate about the validity of the
growth statistics. Productivity in the huge services sector
is especially hard to measure. But if the figures are valid,
they reveal a paradox: a society producing marvelous technical
wonders that it may not be able to absorb into the productive
process.
Concern has focused primarily on the economy's ability to
exploit the new information technologies. Our ability to shuffle
and shift information -- representations of reality ranging
from alphanumeric characters to full-motion video -- has progressed
incredibly swiftly over the past quarter-century. If we could
eat bytes (digitized characters), or MIPS (millions of instructions
per second), or bauds (signaling events per second), our larder
would be a thousand times larger today than it was in 1970.
Information technology, moreover, now touches nearly all businesses,
professions, and industries. And computing and telecommunications
equipment alone -- not including software -- account for one-third
of all business equipment investment. One might think that
IT's breathtaking advances, combined with this level of investment,
would have led to dramatic income and output gains throughout
the U.S. economy. But as Massachusetts Institute of Technology
economist Robert Solow has quipped, "We see computers
everywhere but in the productivity statistics."
Bringing advanced IT into the productive process turns out
to be hardly straightforward. One hurdle is a standard trap
in the game of technical progress -- what J.S. Metcalf and
Ian Miles of the University of Manchester call "the tyranny
of combinatorial explosion." Cluttering the marketplace
today are too many hardware platforms, operating systems,
communication paradigms, and software applications. The resulting
confusion can paralyze users and degrade the rate of technical
progress.
A second problem stems from the fact that IT is "process,"
not "product" technology. It is how firms make goods
and services, not the design of those goods and services.
Introducing new products requires a struggle in the marketplace;
but absorbing powerful process technologies generally involves
an organizational "restructuring" -- a shift in
work flows, skill demands, authority relationships, and staffing
levels. Such changes don't come easily, and bungled implementations
can leave firms worse off.
Finally, recent advances have raised a set of unresolved
issues specific to information technology. IT is business
technology; it affects the way organizations see the world
and make decisions. In some areas, the technology needs complementary
advances to realize its promise. In other areas, the advances
themselves raise managerial problems that, for the moment,
seem beyond the reach of technical solutions.
THE INVESTMENT DECISION
Picking new technology is never easy. But it seemed far simpler
in the 1970s, muses Kavin Moody, executive-in-residence at
Babson College's Center for Information Management Studies,
in Wellesley, Massachusetts. Moody, former head of information
technology at Boston's Gillette Corporation and technology
executive at Bank of Boston, says adoption decisions were
largely controlled by internal corporate hurdle rates -- a
minimum return on investment (ROI) a new technology had to
yield. Firms set different hurdle rates for "revenue-generating"
and "cost-cutting" investments. Moody believes companies
nearly always used the latter, which was also the lower, for
IT shops were cost centers then. They were part of the comptroller's
department, responsible for processing back-office paperwork,
and organizations generally bought technology when it let
them do the work less expensively.
For any technology, estimating future product costs is often
the trickiest part of the purchasing decision. This is because
technology costs -- in IT especially -- tend to fall over
time. If other firms adopt the technology, then vendors can
often expand, realize economies of scale, and lower their
prices; other vendors will surface to offer complementary
or competitive products; and the supply of workers able to
operate and service the technology will rise. Technologies
attractive today thus generally become better values tomorrow.
Delay also lets users avoid getting caught on technology's
"bleeding" edge, or trapped in a technical dead-end.
Counterbalancing these cautions, and also hard to estimate,
are the payoffs. These include the immediate gains and those
to be captured down the road. The longer a shop uses a new
technology, the more adept it becomes. When making a purchase-or-wait
decision, companies must estimate these learning-by-doing
effects. If a firm's competitors adopt an important technology,
one could also avoid a competitive risk by going along with
the herd: adopting the new technology could eliminate a source
of difference between the firm and its competitors. The ROI
calculation for technology investments thus requires a critical
exercise of judgment about the enterprise's ability to exploit
the new capabilities, about the future course of its industry,
and that of its suppliers.
When the returns on a piece of technology did look attractive,
Moody launched a well-developed adoption routine. It began
with a proof-of-concept, continued through system compatibility
and performance trials, and ended, if all went well, in a
standard rollout exercise. In his early days, Moody's organization
brought in computers to automate routine clerical tasks. As
staffing costs absorbed an increasing portion of the corporate
IT budget, a software industry emerged and companies bought
packaged programs that trimmed development, testing, training,
and maintenance costs. Whatever the new technology, the firm
required continuous and rock-solid data processing, so the
adoption process proceeded with a great deal of care.
COMBINATORIAL EXPLOSION
In the old days, IBM's dominant position in the IT industry
simplified the investment process. Big Blue offered a pretty
clear picture of what its new and soon-to-arrive technologies
could do, and how they fit together. So Moody and other corporate
users could plan their purchases and build up in-house expertise
in IBM systems and software.
Today, the corporate IT world is altogether different. Firms
now purchase a great many products from a great many vendors.
For hardware, they pick from mainframes, minicomputers, PCs,
and/or workstations. For operating systems, they could use
Windows (3.1, 95, and/or NT), OS/2, VMS, MVS, and/or a UNIX
or Java. For applications, they could buy WordPerfect, Word,
123, Excel, dBase II, DBII, SAP, Oracle, Sybase, and/or Informix,
and that's just the beginning. For communications, they have
LANs, WANs, client-server applications, and/or intranets.
The speed at which such products appear, get eclipsed, or
are forced to operate with another has been so swift that
IT executives are loath to invest in developing in-house expertise.
Increasingly they seek sophistication from vendors or from
the huge, new IT consulting industry that sells expertise
by the hour. While this is often the only response possible,
it further separates corporate IT executives from developments
in the underlying technology.
Further complicating matters is a parallel fracturing of
corporate control over IT investments. Ever since the late
1970s, when turnkey departmental "solutions" popped
up, often running on new minicomputers, IT has spread beyond
the glass-room confines of the comptroller's back-office paperwork
shop. VPs of manufacturing, human resources, purchasing, distribution,
marketing, sales, you name it, bought self-contained systems
to process information. They often bought systems to raise
quality, revenue, or market share -- payoffs far harder to
quantify than cutting clerical or programming costs. This
complicated the already tricky ROI calculations. Then the
PC and packaged software explosion of the 1980s put IT resources
on the desks of individual workers, from secretaries to research
scientists. The PCs often arrived without any explicit ROI
justification, says Moody, for the payoffs seemed both large
and amorphous. Corporate control over technology investments
had all but broken down.
ANTI-ENTROPY
To bring order out of chaos, firms created a new official
-- the "Chief Information Officer" -- in the mid-1980s.
The CIO generally reports to the Chief Executive or Chief
Operating Officer and is responsible for deploying IT in a
way that boosts the firm's overall performance; the relevant
ROI is the shareholder ROI. Based on his experience at Gillette
and the Bank of Boston, however, Moody likens the job to drinking
from a hydrant.
CIOs need to make sense of developments in the technology
and bring their judgments to bear on corporate IT investments.
They do this by defining organization-wide IT standards and
architectures covering hardware, software, data structures,
and organizational responsibilities. The firm can thus economize
on support and training costs. A more important benefit, but
harder to quantify, is that users around the organization
can access each others' files and expertise. And by limiting
the "tyranny of combinatorial explosion," CIOs simplify
the IT planning process for users throughout the organization.
Despite the utility they bring, says Jerry Kantor, also at
Babson College, the average tenure of a CIO runs only about
three years. Bringing order is a thankless task, says Kantor,
too often viewed by the orderees as an unwanted intrusion.
Users often have their own technical staffs, minds of their
own, and significant clout in the organization. And expectations
often run too high about what IT can do for the firm. But
the source of these conflicts and the reason why CIO tenures
are short lies in the technology itself -- in IT's relentless,
unpredictable advance.
THE TRAVAILS OF REENGINEERING
What also makes IT advances hard to exploit is the fact that
information technology, as "process" technology,
must generally be integrated into a preexisting production
system.
All workplaces are interlocking bundles of machines, workers,
work routines, quirky work-arounds, and shop-specific cultures.
When management introduces a new and improved technology --
whether cybernetic or metal-punching -- it requires adjustments
throughout the workplace. The greater the productivity gain,
the more far-reaching the task, and powerful new IT technologies
typically demand different employee skills, threaten jobs,
disrupt hierarchies, and generally disorient workers.
The problem is classic: The father of "scientific management,"
Frederick W. Taylor, had been instrumental in developing "high-speed
steel," one of a series of advances that let turn-of-the-century
manufacturers process metal with unprecedented economy, speed,
and precision. As machining costs plummeted, what became expensive
was the cost of getting metal on and off the machines and
on to the next station, the cost of inventory stock-outs and
buildups, and the cost of muddled administrative assignments.
Taylor reasoned the road to efficiency lay not through speedier
ways to work metal; this was already cheap. Progress required
better training and rationally reorganized workflows, inventory
controls, and supervisory assignments -- the stuff of scientific
management and industrial (re)engineering.
Modern information technology raises similar issues. Many
leaders in the business process reengineering movement say
that organizations today possess enormously powerful IT resources.
Poor shop floor implementation, however, explains why they
have so little to show for it. Going beyond Taylor, these
critics fault management for failing to recast the business
to best exploit the new technology. Thus in their 1995 book,
Creative Destruction, Richard Nolan and David Croson,
of the Harvard Business School and the Wharton School of Business,
assert that shifting to a "customer-driven, IT-enabled
network organization" could halve the corporate head
count without cutting output, and raise the firm's long-term
growth rate.
A SUCCESS STORY
One New England enterprise to make this transition is Acme
Insurance (not its real name), a property and casualty insurer.
As recently as 1990, Acme operated truly archaic equipment
-- an IBM 1401 with keypunch machines as the input device.
Today, the business runs off a spiffy client-server network,
with document imaging, high-speed links to outside data suppliers,
and custom front-ends supporting its customer-contact agents.
Central to the company's success, says CIO Al Smith (not
his real name), is management's leadership in recasting the
business. Smith, with thirty years' experience under his belt,
could have brought in new systems to run the old business
cheaper and faster. This would have been a standard upgrade
for a process engineer. But the company president had a new
business vision. He saw an opportunity to aggressively expand
sales of the auto and homeowners' insurance using the new
information technology. His business model called for a corps
of telephone agents who, when called by a potential customer,
could issue price quotations and bind insurance coverage at
the end of the initial conversation. Smith's task was to provide
this capability.
Projects like this succeed more often, says Tom Johnson,
of Tenex Consulting in Burlington, Massachusetts, when senior
business executives rely on senior IT managers like Smith.
Hot-shot kids with the latest technical chops are often ignorant
of the business and are out of sync with older executives.
They also tend to lack the maturity needed to manage the delicate
adoption process.
One benefit of Smith's maturity has been his take on the
tradeoff between progress and perfection. Both Smith and Acme
believe in "total quality management," a movement
that sets as its performance target "six-sigma"
consistency -- less than four defects per million. Smith's
upbringing in corporate computing reinforces this commitment
to rock-solid reliability. But he knows that progress today
is not so accommodating. Acme's new system uses five different
computers, layers of interconnected software products, and
webs of communication links. So it's "down" more
often than the old IBM. That's part of the price of the new
capability, says Smith. He expects that TQM's "continuous
improvement" process will steadily raise the sigma count.
But he hopes users and customers will keep demanding more
functionality, which will often come at a cost in reliability.
If the system ever ran at six sigmas, says Smith, "it
could show that people in the firm had run out of ideas for
positive change."
Maturity also helps handle perhaps the greatest barrier to
capturing gains from process technologies -- employee resistance.
Workers will always fight initiatives that cut the firm's
head count in half, as Frederick Taylor should have learned.
This was not the main problem at Acme. The company expanded
its "numerator" -- it took business away from competitors
that used traditional brokerage channels -- so it did not
reduce its head count "denominator." More problematic
at Acme was the inevitable restructuring of jobs and relationships.
Reengineering redefined three types of jobs at Acme Insurance.
Clerks who had simply moved paper now operate the scanners
and index the documents they process. The telephone agents
now decide when to request outside information (at a cost),
when to continue an interview (at a cost of time), when to
terminate, when to quote, and when to refer a more complicated
prospect to an underwriter. And the underwriters now concentrate
on "macro-underwriting" -- pricing risk factors,
not these individual policies. To ease these transitions,
Smith involved these employees throughout the redesign process.
While the changes were uniformly upgrades, the sharp decline
in the value of a worker's former contribution has been unnerving.
And the employees had to be willing and able to upgrade their
skills and assume greater responsibility. MIT's Eric Brynjolfsson,
in a study of a reengineering project, found that "a
surprisingly large subset of workers expressed no desire to
become empowered." Smith reports similar problems. He
says the firm now tries to hire ambitious and flexible workers;
it even wants telephone agents with college degrees. Finding
and keeping such workers, however, has been a challenge.
Such shifts in the demand for labor point to a wider concern.
New process technologies undermine the earning power of workers
who lack complementary skills and personal characteristics.
So the income gains promised by the new technology will not
be distributed equally, and will not be achieved until the
workforce can adjust to these new demands.
THE PARADOX OF PLENTY
A final problem in absorbing IT is specific to the technology.
IT is business technology. It helps us see the world and make
decisions and thus forms part of an organization's management
system. IT's rapid advance and its spread across the enterprise
has produced what Marc Willinger and Ehud Zuscovitch, economists
at France's Université Louis Pasteur, call information-intensive
production systems, with large numbers of workers doing analytical
and managerial work. Willinger and Zuscovitch see significant
economies of scope in such organizations -- the more information
processors at work, the greater the potential for cross-fertilization
and the ability to develop custom products and solutions to
business demands. But as IT has empowered these workers and
firms, it has also raised the demand for information in ways
that currently, and perhaps permanently, outstrip the supply.
The best IT-enabled organizations are full of workers with
initiative and impressive analytical skills. Using powerful
computers and software, they can model the world and make
predictions about the state of affairs. They can quickly design
new materials, machines, or packaging; research markets; analyze
financial statements; or develop sophisticated business plans.
What they often lack is good information about the business.
Corporate "information environments are appalling,"
writes Thomas Davenport of the University of Texas in his
forthcoming Information Ecology; managers, says Davenport,
generally have "exceedingly little accessible information
about their employees, their customers, or even their products."
Davenport's observation is truly ironic, for trunkloads of
information lie all about the IT-enabled organization. As
Shoshanna Zuboff, of the Harvard Business School observes
in her acute The Age of the Smart Machine, information technology
is unique in that it can automatically throw off trace data
that records the workings of a business or technical process.
Data entered into a modern electronic cash register not only
flows into the standard accounting routines and newer inventory
control systems. It can also be gathered, organized, and queried
to yield information on customers or products, or on how shelf-space,
pricing, and the price of a complementary product influence
sales of a particular item.
Accessing this data, however, is hardly straightforward.
Managers, analysts, and workers can hardly jump willy-nilly
into the organization's on-line data systems, for they could
muck it up or run down response times with an ill-constructed
query. So organizations have created separate management information
systems. Data stewards, another new occupational category,
extract data out of on-line systems and ship them to data
"warehouses" that supply the organization's managerial
and analytical needs.
The logistics alone is a major technical challenge, says
Edward Peters of Intersolv, a Rockville, Maryland vendor.
Firms are just learning how to quality-test and transport
such data and where to site the warehouses. A deeper problem
lies in the data itself. Information arriving from around
the enterprise is rarely defined in a consistent fashion,
says Ralph Loftin, a consultant in Newton, Massachusetts.
A category as rudimentary as "customer" lists companies
in the accounts receivable database and human contacts in
sales. Government agencies likewise provide monthly employment
and wage data for the fabricated metals industry, but nothing
for software. Imposing greater consistency and relevance seems
essential. But managers constantly develop "hip-pocket"
dialects to help them understand and organize their work environments,
says Loftin, so imposing complete consistency -- and accessibility
-- is an exercise in hubris costing far too much in time,
money, and meanings lost.
RIDING A ROCKET
James Champy, one of the founding fathers of the business
reengineering movement and now head of Perot Systems' Boston
consulting office, finds IT's most serious failing in the
management suite. He says the general decentralization of
corporate authority in IT-enabled organizations has overloaded
traditional oversight systems. Top managers are responsible
for the performance of the enterprise, he says, but can no
longer effectively supervise their subordinates.
IT allows managers of business units to access information,
model the world, and test out options as never before. As
a result, says Champy, they now propose to senior managers
discontinuous jumps in the scale and scope of their operations.
Competitors are likewise making bolder moves that violate
expectations in a unit's business plan. Because of this instability,
controls such as five-year plans with ROI and cash-flow projections
have lost a great deal of value. Product demonstrations, reviews
of analytical reports, and in-depth discussions of business
plans can provide the necessary understanding. But this takes
an enormous amount of time and attention. IT can augment this
process of discovery, says Davenport, but can never be its
substitute.
So the IT-enabled organization is like an automobile fitted
with a new jet engine. The larger the enterprise and the more
resources it has, the sounder its information infrastructure
and the more ambitious its workers, the greater the potential
for cross-fertilization and the more powerful this engine
might be. But so long as human response times remain constant,
the person atop of the enterprise, who is driving the car,
won't go much faster than he or she did in the past. As the
jet always threatens to accelerate out of control, the driver
might even lack the confidence to continue on at the former
rate of speed. Until organizations fix this fundamental management
problem -- with or without the help of IT -- Champy says we
will not fully harness the productive power of the new technology.
