In the past three decades, businesses have made staggering investments in technology to increase their productivity and efficiency. The technological infrastructure of these companies has become increasingly sophisticated and complex. Most companies today are extremely dependent on their technological infrastructure. Operating without it is like trying to run a business without a telephone or electricity. Businesses depend on their technology at least as much as, perhaps more than, any other utility. However, unlike the telephone and electric industries, technology has not had the benefit of 100 + years to mature under the control of a handful of companies. Thousands of companies contribute to technology, each doing whatever they think will sell the best. Extreme and rapid innovation is the rule, not the exception. Change is the rule, not the exception. The resulting complexity has posed a new challenge for companies: how to realize the potential and anticipated benefits of the investments in an environment of constant change.
