Note publique d'information : The evolution of the multi-billion-dollar computer services industry, from consulting
and programming to data analytics and cloud computing, with case studies of important
companies. The computer services industry has worldwide annual revenues of nearly
a trillion dollars and employs millions of workers, but is often overshadowed by the
hardware and software products industries. In this book, Jeffrey Yost shows how computer
services, from consulting and programming to data analytics and cloud computing, have
played a crucial role in shaping information technology—in making IT work. Tracing
the evolution of the computer services industry from the 1950s to the present, Yost
provides case studies of important companies (including IBM, Hewlett Packard, Andersen/Accenture,
EDS, Infosys, and others) and profiles of such influential leaders as John Diebold,
Ross Perot, and Virginia Rometty. He offers a fundamental reinterpretation of IBM
as a supplier of computer services rather than just a producer of hardware, exploring
how IBM bundled services with hardware for many years before becoming service-centered
in the 1990s. Yost describes the emergence of companies that offered consulting services,
data processing, programming, and systems integration. He examines the development
of industry-defining trade associations; facilities management and the firm that invented
it, Ross Perot's EDS; time sharing, a precursor of the cloud; IBM's early computer
services; and independent contractor brokerages. Finally, he explores developments
since the 1980s: the transformations of IBM and Hewlett Packard; the offshoring of
enterprises and labor; major Indian IT service providers and the changing geographical
deployment of U.S.-based companies; and the paradigm-changing phenomenon of cloud
service.
