Ø A manual calculator called an abacus first appeared around 1200 in China, and then in
Japan around 1600

beneficial industry the world has ever known.”
GDP is defined as the total value of a nation’s goods and services produced
produced within a specific time
period
In the U.S., for example, the IT industry accounted for about 5 percent of the growth in the 1985
GDP.
The Internet added more fuel to the fire, and by 2000, IT’s total contribution to GDP growth was
about 8.6 percent

rate of 10 percent between 1987 and 1995—
1995—nearly twice the rate of the world GDP

The Computer and IT Industries
Ø IT manufacturers and publishers introduce new products for the same
same reasons as their
counterparts in the automotive industry. New products, such as a computer with a
faster microprocessor, a DVD player, or an upgrade to Windows, are
are designed to attract
customers and generate sales
Ø In contrast to the automotive industry, however, the IT industry is not on an annual
cycle
48

Ø The equipment -manufacturing segment of the IT industry is relatively young, and
and
technology, rather than marketing, is the major force that drives

Ø Companies cannot always predict when a new technology will appear,

be incorporated into new products. As a result, the life cycle of computer hardware and
some computer products is short, whereas other products have a long

stages: product
development, product announcement, introduction, maintenance, and

Product Development - Product development often takes place “under wraps.”
Product Announcement - Sometime during the development process, a company
makes a product announcement to declare its intention to introduce

Software begins with an idea that is shaped by a design team and marketing experts
Most software products undergo extensive testing before they are released
The first phase of testing, called an alpha test,
test, is carried out by the software publisher’s inin-house
testing team
Errors, or “bugs,” found during the alpha test phase are fixed, and then the software enters a second
testing phase called a beta test
A beta test is conducted by a team of offoff-site testers
