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.
