"Everyone who has ever stood in line as a clerk [and] fussed over a
finicky, computerized check-out machine, or wondered why computers
seem to complicate life instead of simplifying it, will appreciate
Landauer's cleanly argued and thoroughly readable book."
-- Elizabeth Corcoran, Washington Post
Despite enormous investments in computers over the last twenty years,
productivity in the very service industries at which they were aimed
virtually stagnated everywhere in the world.
If computers are not making businesses, organizations, or countries
more productive, then why are we spending so much time and money on
them? Cutting through a raft of technical data, Thomas Landauer
explains and illustrates why computers are in trouble and why massive
outlays for computing since 1973 have not resulted in comparable
productivity payoffs. Citing some of his own successful research
programs, as well as many others, Landauer offers solutions to the
problems he describes.
While acknowledging that mismanagement, organizational barriers,
learning curves, and hardware and software incompatibilities can play
a part in the productivity paradox, Landauer targets individual
utility and usability as the main culprits. He marshals overwhelming
evidence that computers rarely improve the efficiency of the
information work they are designed for because they are too hard to
use and do too little that is sufficiently useful. Their many
features, designed to make them more marketable, merely increase cost
and complexity. Landauer proposes that emerging techniques for
user-centered development can turn the situation around. Through task
analysis, iterative design, trial use, and evaluation, computer
systems can be made into powerful tools for the service economy.
Landauer estimates that the application of these methods would make
computers have the same enormous impact on productivity and standard
of living that were the historical results of technological advances
in energy use (the steam engine, electric motors), automation in
textiles and other manufacture, and in agriculture. He presents solid
evidence for this claim, and for a huge benefit-to-cost ratio for
user-centered design activities backed by descriptions of how to do
these necessary things, of promising applications for better computer
software designs in business, and of the relation of user-centered
design to business process reengineering, quality, and management.
